Maintaining order of messages in a sip dialog on forwarding
by Daniel Tryba 05 Aug '15

05 Aug '15

Since switching to 4.2.5 (from 3.x) a customer has problems with a buggy user agent (IMHO). What I am seeing now is: provider kamailio customer INVITE1-> INVITE1-> <-Trying <-Trying <-200 OK <-200 OK ACK1-> INVITE2-> INVITE2-> ACK1-> ACK1 arrives 0.007s before INVITE2, but INVITE2 is send 0.004s before ACK1. It looks like this wasn't happening with Kamailio 3.x, it worked fine then (apparently). Can this reordering be (gracefully) prevented somehow (ignoring the fact that during transport reordering can happen)? A Q&D hack looks to be just usleep the reinvite a little. The endpoint is essentially ignoring the reinvite before (and after) the ACK. After a timeout INVITE2 is canceled and after that INVITE1 will be ended with a BYE from provider. kamailio-customer communication is UDP provider-kamailio is tcp when message >= 1300b. INVITE1 is TCP, INVITE2 and ACK1 are UDP.

VIA header question.
by Chad 04 Aug '15

04 Aug '15

Hi list, I need a little help, I am a business owner trying to get Kamailio up and running as a SIP load balancer. I hired a Kamailio consultant to help me do so, but Kamailio is not working and I am getting conflicting information. My Kamailio consultant and my VOIP provider are telling me 2 different things and I don't know which one is right. Kamailio sends SIP traffic to the VOIP provider with 2 VIA headers like this (in this order): Via: SIP/2.0/UDP 10.10.10.254;branch=z9hG4bK7291.6a0bbd2e8fd639a47d7d2de606779e47.0. Via: SIP/2.0/UDP 209.170.201.25:5060;received=10.10.10.102;branch=z9hG4bK742dc03d;rport=5060. The VOIP provider says that is incorrect because they are supposed to reply back to the topmost VIA header so they reply to the 10.10.10.254 IP (which is not public) and the call ends. The VOIP provider says Kamailio should send the VIA headers like this instead: Via: SIP/2.0/UDP 209.170.201.25:5060;received=10.10.10.102;branch=z9hG4bK742dc03d;rport=5060. Via: SIP/2.0/UDP 10.10.10.254;branch=z9hG4bK7291.6a0bbd2e8fd639a47d7d2de606779e47.0. My Kamailio consultant says the way we are sending it is right and that the VOIP provider is processing the call incorrectly. I read that the SIP proxy is supposed to remove the internal header from the 1st example above based on this RFC: https://tools.ietf.org/html/rfc3261#section-16.7 Item: 3. Via "The proxy removes the topmost Via header field value from the response." If that applies to this situation (which I don't know if it does) then Kamailio should be removing the 10.10.10.254 VIA line and only sending 1 VIA header like this: Via: SIP/2.0/UDP 209.170.201.25:5060;received=10.10.10.102;branch=z9hG4bK742dc03d;rport=5060. Which would sort of make the VOIP provider right in that the topmost VIA line would then be the external IP, but how they said to fix it (reversing the VIA lines) is wrong. Does anyone know what the right answer is here? Please let me know. THANKS for your help. -- ^C

MSILO: Archiving every message
by SamyGo 03 Aug '15

Hi, Tried finding anything as weird as I am trying to do on mailing list but couldn't. The idea is to save a copy of the messages on database. MSILO module can keep the message as long as the destination user is offline, or doesn't support method:MESSAGE or expiry timeout. Any ideas will be appreciated. Best Regards, Sammy

Announcement: Kamailio is now systemd-rtc-server
by Alex Balashov 03 Aug '15

03 Aug '15

For immediate release: ATLANTA, GA (1 April 2015)--Evariste Systems LLC, an Atlanta-based software vendor specialising in Kamailio-based service delivery solutions for the VoIP ITSP market, is pleased to announce that it, in collaboration with Red Hat Software and Ringfree Communications, has finalised the absorption of the Kamailio SIP Server into the 'systemd' system management platform for Linux. The new component shall be called 'systemd-rtc-server', or 'Systemd Real-Time Communication Server'. Alex Balashov, principal of Evariste and leader of the tri-vendor collaboration effort, will officially announce the handover of the reigns of the Kamailio project to the personal leadership of Lennart Poettering at the upcoming Systemd Real Time Communications World conference, to be held in Berlin on 27-29 May of this year. John Knight, Director of GNOME 3 Integration and part-time usability consultant at Ringfree Communications, based in Hendersonville, North Carolina,was quick to summarise the triumphs of the long-standing integration effort. Remarked Knight: "The industry has recognised for years that a SIP proxy is a basic building block in the 'init' subsystem of any Linux host. In this age of multimedia communication with voice and video, it was a travesty that systemd handled time synchronisation, network configuration, login management, logging, and console, but not SIP message routing." Sean McCord, a veteran partner at Atlanta-based integrator CyCORE & Docker, was quick to concur: "SIP calls are much easier to troubleshoot with binary logs. Combined with packet captures of TLS-encrypted WebRTC calls, systemd-journald is the ultimate call setup troubleshooting methodology of the responsive, kinetic enterprise." To support the integration of Kamailio into the ecosystem of every major Linux distribution, Evariste has released new 'dbus_api' and 'pulseaudio' modules for the project. Balashov stated, "We fully expect to use the D-Bus API to achieve gnome-session integration with systemd-rtc-server-usrloc, but we aren't going to leave Windows users behind; KamailioSvcHost.exe will support Domain Controller policies for G.722 in Active Directory forests." Despite an aggressive delivery timeline by the tri-vendor consortium behind systemd-rtc-server, industry commentators have widely lambasted the fact that it took so long for Kamailio to become integrated into systemd. Fred Posner, solutions architect at The Palner Group in Fort Lauderdale, Florida, recently wrote in a widely-publicised blog post: "sr-dev have been keeping their heads in the sand for too long. For years now, it has been completely obvious and self-evident to anyone with half a brain that all kinds of VoIP software should be included in systemd. It's a basic building block of the whole OS, having absorbed functionality previously provided by all kinds of packages like util-linux and wireless-tools." John Knight of Ringfree accepted the criticism readily, but advocated a forward-thinking orientation focused on breaking with the uncertainty of the past: "In the absence of a SIP component for routing calls to the PSTN, some people thought, 'systemd has no clear direction apart from the whims of its developers, and is a perpetually moving goal post.' Well, a SIP server should put an end to that whole discussion; that's exactly what was missing, and now that we have systemd-rtc-server, we've eliminated all doubts about the coherence, conceptual integrity and finality of systemd." -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Check if user is registered before reply is routed
by Dmytro Bogovych 01 Aug '15

01 Aug '15

Greetings. Sorry for previous false letter. I want to check if user is registered before reply is routed to its target user agent. Imho it should be like this: onreply_route[MANAGE_REPLY] { if ($rm=="INVITE") { if (registered("location", $ru)) { # Do job - pause for 15 seconds and give chance to reregister } } } But kamailio complains on registered function 0(6274) ERROR: <core> [cfg.y:3295]: yyparse(): misused command registered 0(6274) : <core> [cfg.y:3439]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 1121, column 35: Command cannot be used in the block Documentation confirms - registered() function can be used in REQUEST_ROUTE and FAILURE_ROUTE only. Is it possible to check if user is registered when reply is processed in scripts? Thank you!

Interpretation of Contact header
by Joachim Büchse 30 Jul '15

30 Jul '15

Good day, I’m experiencing some problems with our VoiP providers handling of REGISTER requests. We are using a Gigaset PRO N720 as UAC behind a Juniper SSG 140 with SIP-Alg enabled. This setup kind of works with UDP but our provider wants us to use TCP. With TCP enforced incoming calls don’t work. I’ve done some wire tracing and to me it seems that the providers configuration is to blame, but then - there are many RFCs out there and many NAT and UAC bug workarounds. Anyway, I wanted to get the opinion of “the" experts about how the requests send to the UAS SHOULD be correctly interpreted. The REGISTER requests/responses look like this (outside of the firewall): Protocol TCP! client port 19091 <-> server port 5060 REGISTER sip:pbx.peoplefone.ch SIP/2.0 Via: SIP/2.0/TCP 212.126.160.92:6717;rport;branch=z9hG4bKc1375589832468de63a719eac31156ec From: "Michel" <sip:90780408050@pbx.peoplefone.ch>;tag=2153084485 To: "Michel" <sip:90780408050@pbx.peoplefone.ch> Call-ID: 2825358480@10_10_128_10 CSeq: 1 REGISTER Contact: <sip:90780408050@212.126.160.92:6717;transport=tcp> Max-Forwards: 70 User-Agent: N720-DM-PRO/70.089.00.000.000 Expires: 180 Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, INFO, REFER, SUBSCRIBE, NOTIFY Content-Length: 0 SIP/2.0 401 Unauthorized Via: SIP/2.0/TCP 212.126.160.92:6717;rport=19091;branch=z9hG4bKc1375589832468de63a719eac31156ec From: "Michel" <sip:90780408050@pbx.peoplefone.ch>;tag=2153084485 To: "Michel" <sip:90780408050@pbx.peoplefone.ch>;tag=a0440f545f39b2694d387b475a5f6bc9.b8fc Call-ID: 2825358480@10_10_128_10 CSeq: 1 REGISTER WWW-Authenticate: Digest realm="pbx.peoplefone.ch", nonce="VNqJBVTah9m57ZGGs8b5XCTM3GyaExDy" Server: kamailio (3.2.1 (x86_64/linux)) Content-Length: 0 REGISTER sip:pbx.peoplefone.ch SIP/2.0 Via: SIP/2.0/TCP 212.126.160.92:6717;rport;branch=z9hG4bK9c27afea96e2af4baab2f8d144a588e0 From: "Michel" <sip:90780408050@pbx.peoplefone.ch>;tag=2153084485 To: "Michel" <sip:90780408050@pbx.peoplefone.ch> Call-ID: 2825358480@10_10_128_10 CSeq: 2 REGISTER Contact: <sip:90780408050@212.126.160.92:6717;transport=tcp> Authorization: Digest username="90780408050", realm="pbx.peoplefone.ch", uri="sip:pbx.peoplefone.ch", nonce="VNqJBVTah9m57ZGGs8b5XCTM3GyaExDy", response="764f371a08d258157a249f8d1b852514" Max-Forwards: 70 User-Agent: N720-DM-PRO/70.089.00.000.000 Expires: 180 Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, INFO, REFER, SUBSCRIBE, NOTIFY Content-Length: 0 SIP/2.0 200 OK Via: SIP/2.0/TCP 212.126.160.92:6717;rport=19091;branch=z9hG4bK9c27afea96e2af4baab2f8d144a588e0 From: "Michel" <sip:90780408050@pbx.peoplefone.ch>;tag=2153084485 To: "Michel" <sip:90780408050@pbx.peoplefone.ch>;tag=a0440f545f39b2694d387b475a5f6bc9.6bda Call-ID: 2825358480@10_10_128_10 CSeq: 2 REGISTER Contact: <sip:90780408050@212.126.160.92:6717;transport=tcp>;q=0;expires=180;received="sip:212.126.160.92:19091;transport=TCP" Server: kamailio (3.2.1 (x86_64/linux)) Content-Length: 0 The ip:port the firewall is sending those requests from is ip 212.126.160.92 port 19091. So this does NOT match the port from the Contact header. For TCP this seems rather logical to me, as one cant be listening on a TCP port and use it for sending at the same time. The UAC closes this “register connection” with TCP FIN after the register, and so does the firewall. However unfortunately subsequent requests from the provider (ie UAS) come in on port 19091 (not port 6717 from the Contact header) and the firewall simply drops them. Observations: - the server does NOT include received=212.126.160.92 in the Via of the reponse. According to RFC3581 this is mandatory when rport is present in the request, so this is probably an error in the server. - the server does include received="sip:212.126.160.92:19091;transport=TCP” in the Contact of the response. I didnt see this in any RFC (which means nothing;-) but it could be an error. - after the client received the 200 OK it closes the TCP connection. - the server tries several times to re-contact the client (incoming TCP SYN). However not on port 6717 (defined in the Contact header) but on port 19091 (where the REGISTER came from). RFC3581 defines special behaviour when “rport” is defined in the request (i.e. response should go to the same port the request came from) - however it’s not so clear if this should apply to subsequent (INVITE/OPTIONS) requests from the server to the client. Those are strictly spoken not replies (or are they?). RFC5626 defines that a “proxy” should keep track of the flows over which it received a registration and send requests over the same flow. It is not clear if RFC5626 should be applied. The RFC5626 defines that a UAC includes an “ob” parameter in the Contact field if it whishes further requests over the same flow. Also the RFC mandates a client to add a "reg-id=x" in the Contact field. Both are not the case here, so in short I think RFC5626 should NOT be applied. In which case conecting to the originating port (instead of the Contact port) would be a server error. So in short and if I interpret the RFCs correctly, the client is reachable and should be contacted on Transport: TCP IP: 212.126.160.92 Port: 6717 If anyone who lives and breathes SIP could enlighten me if the UAS is right to call back on 19091 instead of 6717 I would really appreciate it;-)) Best regards, Joachim

Issue with ACK behind NAT

I have Kamailio in a local network with RTPPROXY and NAT MANAGE I have seen an issue with ACK as show when Asterisk sends ACK to Kamailio, it sends to advertised Address instead to Kamailio IP address. What could i add to solve this? route[WITHINDLG] { if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { if (is_method("BYE")) { setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails dlg_manage(); } if ( is_method("ACK") ) { # ACK is forwarded statelessy route(NATMANAGE); } route(RELAY); } else { if (is_method("SUBSCRIBE") && uri == myself) { # in-dialog subscribe requests route(PRESENCE); exit; } if ( is_method("ACK") ) { if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server t_relay(); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404","Not here"); } exit; } } BR

Carrierroute and dispatcher
by Nelson Migliaro 29 Jul '15

29 Jul '15

Hello everybody, I am currently using Kamailio in order to separate traffic based on dialed number. Some traffic goes to several Asterisk in a load balance strategy and other traffic goes to other SIP devices. I use carrierroute module in order to route traffic based on destination. I use scan_prefix to classify traffic and rewrite_host to route the traffic. A destination number usually go to one of 4 asterisk server. I do this in order to load balance the traffic. In order to distribute traffic I use prob (0.25 for each destination). Using this configuration, I have to include on carrieroute table a row for each destination node. Since the amount of destination is huge, I have to repeat configuration in tables. It also complicates maintenance. I was thinking of using a combination of carrierroute and dispatcher module. Carrierroute for classify traffic, strip numbers, and rewrite destination host and dispatcher to distribute the traffic over asterisk. Using this configuration I have to indicate asterisk nodes once in dispatcher table once. Also in carrierroute table I have to indicate each prefix once. I was thinking in something like this. if(!cr_route("carrier", "domain", "$rU", "$rU", "call_id")){ sl_send_reply("403", "Not allowed"); drop; } if(!ds_select_dst("1", "4")) { sl_send_reply("403", "Not allowed"); drop; } t_relay; Does it make sense, or am I complicating everything and there is a magic way to achieve this. Thank you.

Kamailio no audio
by goReeves Admin 29 Jul '15

29 Jul '15

Hi - I just installed Kamailio 4.3.0 on Ubuntu 14.04.2. I can connect using jitsi on windows and csipcimple on the android and do text messaging. However, when I try to do audio callis it seems that the mic is working but the audio out is not functioning. I used the tutorial to do the install so everything in the config files is pretty vanilla except for the database name, use and password. I also installed siremis and added my sip.xxxxx.com as a gateway. On the Ubuntu image I use VPN to a dedicated IP address on which all ports are open. I run web and cloud servers on this machine as well and they all work just fine. I am pretty new to this SIP stuff so it is probably my issue. Here is the network configuration: root@xxxxxxxx-VM:/var/www/siremis-4.2.0# ifconfig eth0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx inet addr:192.168.x.x Bcast:192.168.x.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe84:447a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1579455 errors:0 dropped:0 overruns:0 frame:0 TX packets:1444329 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:346579445 (346.5 MB) TX bytes:625010061 (625.0 MB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:98232 errors:0 dropped:0 overruns:0 frame:0 TX packets:98232 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:262176392 (262.1 MB) TX bytes:262176392 (262.1 MB) ppp0 Link encap:Point-to-Point Protocol inet addr:xxx.xxx.xxx.xxx P-t-P:xxx.xxx.xxx.xxx Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1400 Metric:1 RX packets:1105547 errors:0 dropped:0 overruns:0 frame:0 TX packets:1228003 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:184558026 (184.5 MB) TX bytes:235399612 (235.3 MB) -- Web Administrator <mail:webadmin@goreeves.net> goreeves <https://www.goreeves.net>

double rr and $fs
by Asgaroth 29 Jul '15

29 Jul '15

Hi All, I have kamailio setup and listening on logical interfaces (for failover purposes) and therefore need to force the sending socket on initial messages. We are testing sips+tls at the moment and what we are trying to achive is that the TLS connection occurs from the UAC to the edge proxy (also responsible for the domain) and then force UDP for internal communications to services. What I am comming up against is that when I force the sending socket on the internal interface to UDP, the record route header still shows up as a "sips" request. Then, at the presense server, when generating the NOTIFY it attempts to send it to the proxy using TLS. My understanding was that the record route would set the uri something like "sip:internal_ip" when forcing the sending socket to be "udp:internal_ip". Is my understanding correct, or am I doing something wrong here? An example subscribe message follows, the top most record-route header, from my understanding, should read sip:internal_ip, not sips:internal_ip. Is this the expected behaviour of double rr with these types of messages? How could I ensure that the top most record-route would always be a sip uri (never sips). SUBSCRIBE sips:subscriber@domain.com:5061 SIP/2.0. Record-Route: <sips:proxy_internal_ip;r2=on;lr;ftag=594055226>. Record-Route: <sips:proxy_external_ip:5061;transport=tls;r2=on;lr;ftag=594055226>.

Kamailio - Missing INVITEs
by Ali Taher 28 Jul '15

28 Jul '15

Hello, I connected Kamailio to a postgresql database (through sqlops module) and fetching result from a table containing around 300K records , where time processing of the single query is taking around 12 ms. I noticed that on huge load (around 200 - 300 calls per second) Kamailio is not processing all INVITE packets. For instance , I initialized a counter in Kamailio that increments on every INVITE , and on the other hand I counted the number of INVITEs found in Wireshark. I got a big difference (from 30K INVITES in Kamailio , I got 15K in Kamailio), though no errors were raised in kamailio log. How can I proceed in order to detect the problem? :( Any help would be appreciated. Regards, Ali

RR module - Fail detecting strict routing
by Antonio Reale 28 Jul '15

28 Jul '15

Hi all, I have the following scenario: U1 (caller) ---> P1 (192.168.0.245, kamailio 4.3, loose-router) ----> P2 ----> (192.168.0.101, strict router) ----> .... ----> U2 (called) When U2 answers the call, at P1 arrives the 200 OK with: Record-Route: <sip:0000000011@192.168.0.101;transport=udp;pgw-call=call-28d2e> Record-Route: <sip:192.168.0.245;lr=on> The problem is that the ACK from U1 is forwarded from kamailio to P2, as if P2 is a loose router. P2 drops the ACK message. From kamailio logs I see: Jul 14 10:07:44 P1 /usr/sbin/kamailio[15908]: DEBUG: rr [loose.c:88]: is_preloaded(): is_preloaded: No Jul 14 10:07:44 P1 /usr/sbin/kamailio[15908]: DEBUG: rr [loose.c:783]: after_loose(): Topmost route URI: 'sip:192.168.0.245;lr=on' is me Jul 14 10:07:44 P1 /usr/sbin/kamailio[15908]: DEBUG: rr [loose.c:869]: after_loose(): URI to be processed: 'sip:0000000011@192.168.0.101;transport=udp;pgw-call=call-289ce' Jul 14 10:07:44 P1 /usr/sbin/kamailio[15908]: DEBUG: rr [loose.c:878]: after_loose(): Next URI is a loose router Why after_loose function considers the next URI a loose router? The Route HF in the ACK with the URI of the next hop does not contain ;lr . It seems that the function is_strict fails detecting the strict router. Thanks. Regards. Antonio

SIPCapture and Message Queues
by Grant Bagdasarian 27 Jul '15

27 Jul '15

Hello, Would it be possible to send the messages captured by the sipcapture module to a message queue instead of inserted directly into a database? Be it DMQ or SQL Server Service Broker Queues, etc. Or maybe another approach, executing a stored procedure instead of an insert statement? I couldn't find a way to accomplish this, but maybe someone has a brilliant idea how to accomplish any of the above. Regards, Grant

Problem Storing USRLOC Additional Attributes
by Luca Mularoni 27 Jul '15

27 Jul '15

Hi All, I'm using kamailio 4.2.5 (compiled from source and aligned up to commit [00a36ae07c587992d6486277ce2e9ae6c009685f]). In order to enrich users data collected during registering phase, I would like to store them in USRLOC Additional Attributes through the use of 'xavp_contact' structure, but I'm having problems storing them. Below relevant chunks of config: ... # ----- usrloc params ----- modparam("usrloc", "db_mode", 2) modparam("usrloc", "use_domain", 0) modparam("usrloc", "xavp_contact", "ulvals") ... route[REGISTRAR] { ... # Just an example $xavp(ulvals=>A) = "A"; $xavp(ulvals[0]=>B) = "B"; $xavp(ulvals[0]=>C) = "C"; $xavp(ulvals[0]=>D) = "D"; ... if (!save("location")) sl_reply_error(); exit; } route[LOCATION] { ... if(!lookup("location") { # Handle Failure ... } # Print USRLOC Additional Attributes # Just an Example $var(i) = 0; $var(N) = $branch(count); while($var(i)<=$var(N)) { xlog("LOC - [$var(i)] - A [$xavp(ulvals[$var(i)]=>A)]\n"); xlog("LOC - [$var(i)] - B [$xavp(ulvals[$var(i)]=>B)]\n"); xlog("LOC - [$var(i)] - C [$xavp(ulvals[$var(i)]=>C)]\n"); xlog("LOC - [$var(i)] - D [$xavp(ulvals[$var(i)]=>D)]\n"); $var(i) = $var(i) + 1; } ... } And this is the relevant chunk of syslog when a local subscriber is found in 'location' table: ... LOC - [0] - A [A] LOC - [0] - B [<null>] LOC - [0] - C [<null>] LOC - [0] - D [D] ... Summing up, it seems that when xavp structure is stored in memory, just first and last elementsare inserted. In real config I'm using more than 4 attributes and behaviour is the same: just first and last are stored. I've tried also with modparam("usrloc", "db_mode", 0) but the problem remains. Where I'm wrong in using this structure? Or it could be a bug? Thank You in advance for your help Luca Mularoni

Changing acc_cdrs time and duration columns from varchar to int/float
by mayamatakeshi 27 Jul '15

27 Jul '15

Hello, I am planning to enable acc cdr in my kamailio 4.1 server. I am testing in my lab and it is working fine. However, when I check the table definition I see this: mysql> describe acc_cdrs; +------------+------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+------------------+------+-----+---------+----------------+ | id | int(10) unsigned | NO | PRI | NULL | auto_increment | | start_time | varchar(32) | NO | MUL | | | | end_time | varchar(32) | NO | | | | | duration | varchar(32) | NO | | | | +------------+------------------+------+-----+---------+----------------+ 4 rows in set (0.00 sec) The *_time and duration columns are defined as varchar. Because of this, i need to perform a cast when doing queries: select * from acc_cdrs where cast(start_time as unsigned) >= 1437120622; which would cause extra processing in the db server. So I experimented changing these columns to "int unsigned" and to "float unsigned" and it worked for both without problems (records properly added to acc_cdrs and no errors in kamailio.log): alter table acc_cdrs modify start_time int unsigned; alter table acc_cdrs modify end_time int unsigned; alter table acc_cdrs modify duration int unsigned; alter table acc_cdrs modify start_time float unsigned; alter table acc_cdrs modify end_time float unsigned; alter table acc_cdrs modify duration float unsigned; So I am thinking in doing this in my production server but I would like to know if there is any potential risk of doing this (as I am not sure why it was decided for these fields to be varchar instead of a numeric type).

New SIP INVITE from UAS (new dialogue)
by Joao Alves 27 Jul '15

27 Jul '15

Hi, What would be the best way to generate and send an INVITE message generated by the Kamailio server. This would be for a new dialog session, UAS initiated (e.g. to make a click 2 call like service). I've tried the $uac_req(method)="INVITE"; uac_req_send(); but didn't work. I gather something would be needed first to open the dialogue before doing it but couldn't find it on the dialogue module.

Issues sending SIP UPDATE inside an existing dialogue.
by Joao Alves 24 Jul '15

24 Jul '15

Hi, I need to send an SIP UPDATE inside an existing dialogue (in order to update the SDP offer). I've been using the following uac functions from the command file. $uac_req(method)="UPDATE"; $uac_req(ruri)=$shv(userAcontact); $uac_req(turi)=$tu; $uac_req(furi)=$fu; $uac_req(callid)=$ci; $uac_req(hdrs)="Content-Type: application/sdp\r\n"; $uac_req(body)=$var(sdp); # uac_restore_from(); uac_req_send(); As a result, the SIP UPDATE is being sent but since the original From Tag is not being used (i.e. and a new tag is generated), the SIP client (sipML5) does not recognize it as part of the existing dialogue. Attach is a pcap of the test made. Subsequently, I've also tried to recover the from using uac_restore_from() function but got the following an error message.

dialog keepalive timeout - which parameter rules it?
by Andrey Utkin 24 Jul '15

24 Jul '15

What happens if dialog parties don't respond to keepalive requests sent by dialog module? It looks it is not coded in modules/dialog, I guess it can be set in t_uac_prepare() from modules/tm/uac.c. Please explain what timeout or lifetime parameters rule - at which delay the unanswered keepalive request sent by Kamailio within dialog triggers dialog termination. Thanks a lot. -- Andrey Utkin

dmq_usrloc replication and max_contacts
by Asgaroth 24 Jul '15

24 Jul '15

Hi All, I have a situation where I have 2 devices registering with the same AOR, I have the registrar module's max_contacts parameter set to 1 and I use the 0x04 flag on the save function. When I use dmq_usrloc for replication, I can see 2 contacts registered for the AOR on the "client" nodes whereas the node where the actual registration took place only has 1 contact for the AOR. Is this expected behaviour of the dmq_usrloc module in terms of registration or have a come accross another bug? Thanks

"kamctl ul show"/xmlrpc ul.lookup AOR not found for valid registration
by Asgaroth 24 Jul '15

24 Jul '15

Hi All, I have a situation where a device has successfully registered and its location saved/stored in memory. I can see all the stored information when I issue a "kamctl ul show" However, if I perform a kamctl ul show subscriber@domain, where the 'subscriber@domain' is copied/pasted from the output of the "kamctl ul show" command, it results in an AOR not found error. However, with other AOR's on the same registrar, the "kamctl ul show subscriber@domain" works. I checked the usernames for the failed commands, and I dont see anything obvious, they are a combination of lower/upper-case leters and digits. String length is around 24 characters for the username (the username table for the subscriber is 64 characters). I'm not sure what elese to check to see why the AOR lookup for these particular clients are failing when they are indeed registered. All other functions around the lookup seem to work, for example, a location lookup for these AOR's are working. I wonder if I have come accross an issue with the kamctl function and/or the equivilient xmlrpc ul.lookup method. Any thoughts on this would be greatly appreciated. Thanks

sending INVTE with Digest values

I am registering my client to kamailo successfully. client --> Register --> kamailioclient <-- 401 with nonce value <-- kamailioclient --> Register with nonce and md5 response values --> kamailioclient <-- 200ok <-- kamailio However, when the client sends an invite with the same digest values, kamailio sends a 407 request for another challenge: client --> Invite with the same nonce and md5 response values --> kamailioclient <-- 407 <-- kamailio I am thinking the same digest values from register could be used for making calls.

Dispatcher module number of calls
by Alberto Sagredo 23 Jul '15

23 Jul '15

Hi Hi have read documentation but it seems dispatcher does not keep how many calls has been dispatched or currently are in any of dispatcher destinations I have take a look to code on: http://lists.sip-router.org/pipermail/sr-users/2012-July/073919.html But it seems to use calls limit per user, I would need to establish a limit per dispatcher destination i order to do not send more calls. Any idea where to look for? I have take a look to DMQ module, that maybe i could to use to spread information of how many calls to every destination but do not know how to extract calls from kamailio that have been dispatched to this destination using disptcher module.

Kazoo like load balancing
by Jurijs Ivolga 23 Jul '15

23 Jul '15

Hi, First of all I would like to mention, that I'm very new to Kamailio. :) My target is to create simple load-balancing similar what have Kazoo, basically 2 servers will share same domain name. I installed 2 Kamailio 4.3 servers and configured this 2 servers with one domain address. I used almost default config with: #!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_MULTIDOMAIN #!define WITH_NAT #!define WITH_NATSIPPING Calls are going through if I register both clients to one server. But all my calls are failing, when clients are registered to different servers with error "404 Not Found". Maybe somebody can give me a hint how to make this work. Thank you! With kind regards, Jurijs

Port 5061 Issue
by Ankhit Vivekananda 23 Jul '15

23 Jul '15

Hello, I have configured kamailio 4.0.4 long back. Now, I wanted to enable the usage of port 5061 with TLS. By doing so, the client(video camera) can place outgoing calls fine. But while receiving an incoming call, the message does not get sent out to the other client. Hence, the call fails. I can place and receive calls on port 5060 successfully without any issues. Can anyone please tell me why port 5061 is giving me a problem. Also, as a test, I set up kamailio on another machine(version 4.1) and 5061 works fine in all directions. It's only on the other machine that I have problems with. Appreciate any help! Thank you, Ankhit

htable replication between several kamailio's through dmq
by José Seabra 22 Jul '15

22 Jul '15

Hello there, I'm using the dmq and htable modules to limit the number of concurrent calls in several kamailio's servers. Every call that one kamailio server receives, kamailio increments a htable variable that is replicated to other kamailios through dmq, but if one of these kamailios fails or is restarted it looses the data from htable variable used to count the number of calls and it is not recovered again when kamailio starts again. Is there any way to recover the data from htable variable when kamailio starts, from another kamailio instances through dmq module? Best Regards -- Cumprimentos José Seabra

dmq_is_from_node() issue
by Asgaroth 22 Jul '15

22 Jul '15

Hi All, I have an issue with the dmq_is_from_node() function, whereby it does not detect a node is on the bus if it has been removed from its "table" due to previously failed, i presume, ping requests. I have the following snippet in my main routing block: if(is_method("KDMQ")) { if (dmq_is_from_node()) { dmq_handle_message(); exit; } else { xlog("L_INFO", "KDMQ message recieved from node not on our bus!! ($si:$sp) Dropping."); exit; } } I have the following dmq module parameters enabled for dmq: modparam("dmq", "server_address", DMQ_ADDRESS) modparam("dmq", "notification_address", "sip:lb.domain.com:5060") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) DMQ_ADDRESS is set to each of the addresses in the lb.domain.com for each local kamailio instance lb.domain.com resolves to the following addresses: 10.6.0.109 10.6.0.110 10.6.0.111 If I start up the 1st instance of kamailio and do not start the other 2 within the default ping timout then I get the expected log message of dmq removing the nodes from its table, for example: kamailio[26657]: ERROR: dmq [notification_peer.c:588]: notification_resp_callback_f(): deleting server sip:10.6.0.111:5060 because of failed request kamailio[26657]: ERROR: dmq [notification_peer.c:588]: notification_resp_callback_f(): deleting server sip:10.6.0.110:5060 because of failed request However, if I then start one, or both, of the other nodes, then the KDMQ requests are dropped due to my snippet above, I presume, because dmq_is_from_node() checks its "active" table. See messages below as an example of the above snippet in action: kamailio[26656]: INFO: <script>: KDMQ message recieved from node not on our bus!! (10.6.0.110:5060) Dropping. kamailio[26656]: INFO: <script>: KDMQ message recieved from node not on our bus!! (10.6.0.111:5060) Dropping. Is this expected behaviour from the dmq_is_from_node() function? I would have expected it to always check the addresses resolved in the notification address, or am I using this function in a manner not intended. Any suggestions/tips would be greatly appreciated. Thanks

RFC: about the self signed tls certificates
by Daniel-Constantin Mierla 22 Jul '15

22 Jul '15

Hello, (cross-posting as it impacts users as well) Currently we generate and install the TLS self-signed certificates when tls module is installed, including them in the debian packages (and I guess in rpms). Debian has a policy of reproducible builds, meaning that from same source tree snapshot the same binary packages should result. Even more important considering the impact on security, it would be better that the certificates are generated locally on the installation server, to be distinct. Right now, people relying on default installation config/certificates (and I guess there are many, at least in testing phase), are exposed to eavesdropping, because the private key is available in public packages. My proposal is to move generation of self signed certificates to kamctl. There can be a kamctl.tls file to be deployed by the tls package (same is done by kamctl.mysql, being part of mysql package), which should add a new group of commands, among them something like: kamctl tls generate-certificate The drawback is that before enabling tls and starting kamailio, one has to run the above command. We can document that in tls module readme and in kamailio.cfg in the comments related to WITH_TLS define. Anyone with comments, pros/cons? Other suggestions on how to address the reproducible builds as well as solve the security issue for the default installation?

usage of t_flush_flags() in event_route
by Andrew Pogrebennyk 20 Jul '15

20 Jul '15

Hi Daniel and others, I'm having a problem with acc module if I'm using the event_route/ branch-failure: say, the call comes from the app server and goes to the registered user. We arm the the failure route and per-branch failure route for the 302 redirect from the UA. We explicitly reset the accounting flags because we don't want to account the calls from the app server. The transaction is created implicitly by the t_relay(). Now if the UA responds with the 302 response and we are going to process that, we want to create an acc record for the new target from 302 message because this call may incur additional costs. I'm setting the accounting flags and calling t_flush_flags() but that doesn't work (no accounting record). Any idea if I'm doing something wrong or maybe there's a bug when changing the flags and then calling t_flush_flags from the event_route? Here are the module parameters: modparam("acc", "early_media", 0) modparam("acc", "report_ack", 0) modparam("acc", "report_cancels", 1) modparam("acc", "detect_direction", 1) modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 2) modparam("acc", "failed_transaction_flag", 3) modparam("acc", "db_url", PAIR_URL) modparam("acc", "db_extra", "src_user=$fU;src_domain=$fd;dst_ouser=$tU;dst_user=$rU;dst_domain=$rd") modparam("acc", "multi_leg_info", "src_leg=$avp(i:901);dst_leg=$avp(i:902)") modparam("acc", "time_mode", 2) modparam("acc", "time_attr", "time_hires") modparam("acc", "cdr_log_enable", 0) FTR, we tried 4.1.6 and 4.1.8. And here is the event route (with flags defined like this: flags FLAG_ACC_DB:1, FLAG_ACC_MISSED:2, FLAG_ACC_FAILED:3, ...): event_route[tm:branch-failure:redirect] { route(ROUTE_STOP_RTPPROXY_BRANCH); if($T_rpl($rs) == 301 || $T_rpl($rs) == 302) { # initialise variables when entering failure route route(ROUTE_INITVARS); # these need to be avps because we need it in reply/failure-route $(avp(s:from_faxserver)[*]) = 0; $(avp(s:to_faxserver)[*]) = 0; $(avp(s:cf_from_pstn)[*]) = 0; $(avp(s:from_pstn)[*]) = 0; $(avp(s:proxylu_from_pstn)[*]) = 0; $(avp(s:lcr_flags)[*]) = 0; $(avp(s:em_call)[*]) = 0; $(avp(s:from_pbx)[*]) = 0; $(avp(s:p_to_device)[*]) = 0; $(avp(s:p_to_group)[*]) = 0; $(avp(s:is_primary)[*]) = 0; # now let's process a 30x $(avp(s:acc_state)[*]) = "cfb"; $(avp(s:orig_acc_caller_user)[*]) = $avp(s:acc_caller_user); $(avp(s:orig_acc_caller_domain)[*]) = $avp(s:acc_caller_domain); $(avp(s:acc_caller_user)[*]) = $avp(s:acc_callee_user); $(avp(s:acc_caller_domain)[*]) = $avp(s:acc_callee_domain); $(avp(s:caller_uuid)[*]) = $avp(s:callee_uuid); $(avp(s:callee_uuid)[*]) = $null; # the $var(no_acc) is 0 at this point but the flags may have been reset # if this is a call from PBX user - we do want accounting for the 302 redirect if(isflagset(FLAG_ACC_DB)) { xlog("L_NOTICE", "++++++ ACC flag is set - [% logreq -%]\n"); } else { xlog("L_NOTICE", "------ ACC flag is NOT set - [% logreq -%]\n"); } setflag(FLAG_ACC_FAILED); setflag(FLAG_ACC_DB); t_flush_flags(); # get last URI from destination-set and set it as R-URI $var(contact) = $T_rpl($ct); $var(contact) = $(var(contact){nameaddr.uri}); if($var(contact) == 0 || $var(contact) == $null) { xlog("L_ERROR", "Failed to fetch contact '$ct' from 301/302 - [% logreq -%]\n"); acc_db_request("480", "acc"); $var(announce_handle) = "callee_tmp_unavailable"; $var(announce_set) = $xavp(callee_real_prefs[0]=>sound_set); $(avp(s:announce_code)[*]) = 480; $(avp(s:announce_reason)[*]) = "Temporarily Unavailable"; route(ROUTE_EARLY_REJECT); } $ru = $var(contact); xlog("L_NOTICE", "Redirect from UAC intercepted - [% logreq -%]\n"); $(avp(s:forwarder_cli_userprov)[*]) = $T_rpl($tU); $(avp(s:forwarder_domain_userprov)[*]) = $T_rpl($td); $var(forward) = 1; $var(redirected_forward) = 1; route(ROUTE_LOAD_CALLER_PREF); route(ROUTE_FIND_CALLEE); } } Thanks.

Missing BYE at the far end
by Kliment Toshkov, Netfinity JSC 20 Jul '15

20 Jul '15

Dear colleagues, We have an issue with a couple of peers - when the called party hangs up, they (the peer) does not receive the appropriate BYE message and call appears as still connected at peers end. Then it drops after 30 seconds and sends us BYE. Current setup is the following: PEER IP > KAMAILIO 4.2.2 > (Asterisk PBX 1, 2, 3, …, N) We provision only termination services, which is: 1) peer calls us 2) Kamailio chooses destination using dispatcher module 3) forwards the call to it. Attached is captured trace. Clearly BYE is retransmitted a few times, then request for UPDATE is received but it is not possible to answer it because the call is already hung up (as far as I understand). Kamailio routing file is available upon request. Thank you in advance!

Kamailio & Asterisk SIP Registration Forwarding - Asterisk replies 401 Unauthorized
by Ben Fitzgerald 20 Jul '15

20 Jul '15

Hi, I've been following this integration tutorial http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb and have a successful registration and I can even make calls through my asterisk box. However what is unusual to me is that every time a phone registers with Kamailio, that is forwarded to Asterisk (as expected), yet Asterisk replies with 401 Unauthorized. Oddly enough the phone registers and can still make calls. What worries me is that as we scale to 100's of cps, this seemingly erroneous message may slow down Asterisk because it's trying to handle authentication for users which have already been authenticated by Kamailio. If this behavior is expected, then that would be good to know as well. This is the sip debug from ASTERISK (I have replaced IP's with the names of the servers): <--- SIP read from TCP:kamailio:41205 ---> REGISTER sip:asteriskIP:5060;transport=tcp SIP/2.0 Via: SIP/2.0/TCP kamailio;branch=z9hG4bK998f.2846e405000000000000000000000000.0 To: <sip:40081@asteriskIP> From: <sip:40081@asteriskIP>;tag=32fda68bf54efeeb04e3edc67b53c63d-cfb0 CSeq: 10 REGISTER Call-ID: 0005ce130bcee5c4-26538@kamailio Max-Forwards: 70 Content-Length: 0 User-Agent: kamailio (4.3.0 (x86_64/linux)) Contact: <sip:40081@kamailio:5060> Expires: 3600 <-------------> --- (11 headers 0 lines) --- Sending to kamailio:5060 (no NAT) Sending to kamailio:5060 (no NAT) <--- Transmitting (no NAT) to kamailio:5060 ---> SIP/2.0 401 Unauthorized Via: SIP/2.0/TCP kamailio;branch=z9hG4bK998f.2846e405000000000000000000000000.0;received= kamailio From: <sip:40081@asteriskIP>;tag=32fda68bf54efeeb04e3edc67b53c63d-cfb0 To: <sip:40081@asteriskIP>;tag=as404bac9a Call-ID: 0005ce130bcee5c4-26538@ kamailio CSeq: 10 REGISTER Server: Asterisk PBX 11.6-cert2 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH Supported: replaces, timer WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="262b338e" Content-Length: 0 <------------> Scheduling destruction of SIP dialog '0005ce130bcee5c4-26538@ kamailio' in 32000 ms (Method: REGISTER) Scheduling destruction of SIP dialog '0005ce130bcee5c4-26538@ kamailio' in 32000 ms (Method: REGISTER) Really destroying SIP dialog '0005ce130bcee5c1-26536@ kamailio' Method: REGISTER ========================= sip.conf for kamailio trunk: [kamailio-inbound] type=friend dtmfmode=auto host=kamailioIP allow=all context=sipout insecure=port,invite canreinvite=no ======================== Asterisk version: 11.6-cert2 Kamailio version: 4.3 Benjamin Fitzgerald LETS Corporation (925) 235-1154 ben(a)letscorp.us *******Confidential Notice: This message is intended only for the use of the individual or entity to which it is addressed and may contain information that is privileged, confidential and exempt from disclosure under applicable law.

Double Record-Route to subscriber with multiple locations on different SIP transports
by Andrey Utkin 17 Jul '15

17 Jul '15

Hi! We found that we need double Record-Route when we call from one SIP transport to another (let's say, TCP -> TLS), because without |transport=" hint in Record-Route, mobile Linphone app sends messages (INVITE reply, ACK, BYE) via UDP, even if configured for another transport. record_route_advertised_address() is told to add double RR if needed, automatically, so we use it. But the subscriber (the receiver of call) can have multiple registered locations, let's say, one connected via TCP, and another via TLS. So we need to handle each call branch added by lookup(). But adding record_route_advertised_address() ONLY to branch_route attached by t_on_branch() doesn't execute if there's only one location. Having record_route_advertised_address() just in routing script after lookup() seems wrong because it seems unable to edit it for other branches (I don't remember if I have tested this and have proven a failure, or this is just my speculation). So we have added it in both places - right under lookup(), and in branch_route. But in this case we have an error logged: ERROR: rr [rr_mod.c:337]: w_record_route_advertised_address(): Double attempt to record-route Could anyone explain what would be the most correct solution? What is intended behaviour of branch_route? Is it omitted from execution on "primary" branch of call? Is there any parameter which could help? Thanks in advance. -- Andrey Utkin

Dialogue restore after initial processing
by Joao Alves 17 Jul '15

17 Jul '15

Hi, I'm trying to restore a SIP session dialogue context and found dlg_get(callid, ftag, ttag) function for that. However, I cannot access the To tag. I noticed on the 180 RINGING there was already an self-generated included on this response, but I also could not access its value. When receiving the SIP INVITE request I used the dlg_manage() and the context was initially stored. if(is_known_dlg()) { xlog("Request $rm from $ci is in-dialog\n"); xlog(">>From tag is $ft and To tag is $tt\n"); # Needed to later restore the dialog $shv(ftag)=$ft; $shv(ttag)=$tt; } 15(49100) ERROR: <script>: Request INVITE from 76589ZWQ5NzIyYjMzNDI1YjVjM2E5ZWU5NjhkYzEyNjE3MzQ is in-dialog 15(49100) exec: *** cfgtrace:request_route=[MATRIX] c=[/etc/kamailio/kamailio.cfg] l=1021 a=25 n=xlog 15(49100) DEBUG: pv [pv_core.c:376]: pv_get_xto_attr(): no Tag parameter 15(49100) ERROR: <script>: >>From tag is 8fd06474 and To tag is <null> Since there was a self-generated one (after the 180 RINGING being sent), I rechecked the $tt and $dlg(to_tag) values and both still returned null values. 15(49100) DEBUG: tm [t_lookup.c:1083]: t_check_msg(): DEBUG: t_check_msg: T already found! 15(49100) DEBUG: <core> [tcp_main.c:2196]: tcpconn_send_put(): send from reader (49100 (15)), reusing fd 15(49100) DEBUG: <core> [tcp_main.c:2430]: tcpconn_do_send(): sending... 15(49100) DEBUG: <core> [tcp_main.c:2464]: tcpconn_do_send(): after real write: c= 0x7effdf7da860 n=396 fd=5 15(49100) DEBUG: <core> [tcp_main.c:2465]: tcpconn_do_send(): buf= SIP/2.0 180 ringing Via: SIP/2.0/TCP 192.168.1.5:58751;branch=z9hG4bK-524287-1---a64e0a42199ee419;rport=61134;received=85.138.200.8 To: <sip:1001@decasa.website>;tag=a6a1c5f60faecf035a1ae5b6e96e979a-f6a3 From: "1000"<sip:1000@decasa.website>;tag=8fd06474 Call-ID: 76589ZWQ5NzIyYjMzNDI1YjVjM2E5ZWU5NjhkYzEyNjE3MzQ CSeq: 1 INVITE Server: kamailio (4.3.0 (x86_64/linux)) Content-Length: 0 ..., shmem=0x7effdf7e1e00: SIP/2.0 180 ringingght(): DEBUG: reply sent out. buf=0x7effec023bf8: SIP/2.0 180 ringing 15(49100) DEBUG: tm [t_reply.c:657]: _reply_light(): DEBUG: _reply_light: finished 15(49100) DEBUG: sl [sl.c:272]: send_reply(): reply in stateful mode (tm) 15(49100) exec: *** cfgtrace:request_route=[MATRIX] c=[/etc/kamailio/kamailio.cfg] l=1031 a=25 n=xlog 15(49100) DEBUG: dialog [dlg_hash.c:640]: dlg_lookup(): ref dlg 0x7effdf7e1bf0 with 1 -> 2 15(49100) DEBUG: dialog [dlg_hash.c:642]: dlg_lookup(): dialog id=5769 found on entry 128 15(49100) DEBUG: dialog [dlg_hash.c:858]: dlg_unref(): unref dlg 0x7effdf7e1bf0 with 1 -> 1 15(49100) ERROR: <script>: Dialog To Tag: <null> <== xlog("Dialog To Tag: $dlg(to_tag)\n"); 15(49100) exec: *** cfgtrace:request_route=[MATRIX] c=[/etc/kamailio/kamailio.cfg] l=1033 a=25 n=xlog 15(49100) DEBUG: pv [pv_core.c:376]: pv_get_xto_attr(): no Tag parameter 15(49100) ERROR: <script>: >>From2 tag is 8fd06474 and To tag is <null> Many thanks, Joao Alves Solution Architect, Unified Communications This message and the information contained herein is proprietary and confidential and subject to the Amdocs policy statement, you may review at http://www.amdocs.com/email_disclaimer.asp

Configuring Kamailio as SIP Proxy

16 Jul '15

Hi, I have terminals of video conference which are in public IP ( *DMZ*). I installed kamailio (4.2) which works correctly, it is also in IP pulique (*DMZ*). I wish configured the /kamailio.cfg/ file, so that kamailio works in *proxy SIP*. And declared my CODEC of visoconférence in URI, example: 'DR London(a)domaine.fr'. In what part of the file ( *kamailio.cfg* ) do I have to make these modifications ? This to avoid the flooding. How possibly write the rule of corresponding ACL. Thank you for your help.

*Hi Experts,* *I would like to ask you if some of you have already come across this problem.* *We are integrating Kamailio all in one Solution (P/I/S-CSCF having all same IP only communicating between each other on different ports) taken from Carsten Bock example against an external HSS.* *The flow is as follows:* UE HSS P-CSCF I-CSCF S-CSCF --------------------------Sip Register--------------------------> ----------Sip Register---------> <---------------------------------UAR-------------------------------- ---------------------------------UAA--------------------------------> --------------SIP Register-------> *The last step "SIP Register" from I-CSCF to S-CSCF is not happenning for some reason.* *The Received AVP in UAA is "First Time Registration 2001 code".* *Now we do not know whether this UAA answer is OK, or some other URI is badly defined which could explain why I-CSCF has trouble contacting S-CSCF.If someone have some logs, traces which could be used as a reference for this scenario would be greatly appreciated.* *Find theses messages we get in the shown logs below:* *Thank you* *JanThis file /rtc/kamailio_icscf/kamailio.cfg is a function which sends message to SCSCF, see below:* route[REG_UAR_REPLY] { #xlog("$$avp(s:uaa_return_code) = $avp(s:uaa_return_code)\n"); #this is async so to know status we have to check the reply avp switch ($avp(s:uaa_return_code)){ case 1: #success if (I_scscf_select("0")){ t_on_failure("register_failure"); t_on_reply("register_reply"); #now relay to appropriate SCSCF if (!t_relay()) { t_reply("500", "Error forwarding to SCSCF"); } } else {#select failed I_scscf_drop(); t_reply("500", "Server error on SCSCF Select (UAR)"); } break; case -1: #failure xlog("L_ERR", "UAR failure - error response sent from module\n"); break; case -2: #error xlog("L_ERR", "UAR error - sending error response now\n"); t_reply("500", "UAR failed"); break; default: xlog("L_ERR", "Unknown return code from UAR, value is [$avp(s:uaa_return_code)]\n"); t_reply("500", "Unknown response code from UAR"); break; } } *Kamailio is getting an answer: "t_reply("500", "Error forwarding to SCSCF");"* *which means that th function I_scscf_select("0") is fine but the other function called "t_relay", is the one generating the error "Error forwarding to SCSCF".* *I-CSCF is not able to send the SIP message to S-CSCF, see this log below:* Jul 16 14:59:22 cw-aio /usr/sbin/kamailio[31604]: ERROR: tm [t_fwd.c:1711]: t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches Jul 16 14:59:23 cw-aio /usr/sbin/kamailio[31599]: INFO: ims_icscf [cxdx_uar.c:71]: create_uaa_return_code(): created AVP successfully : [uaa_return_code] Jul 16 14:59:23 cw-aio /usr/sbin/kamailio[31605]: INFO: ims_icscf [cxdx_avp.c:137]: cxdx_get_avp(): cxdx_get_server_name: Failed finding avp Jul 16 14:59:23 cw-aio /usr/sbin/kamailio[31605]: INFO: ims_icscf [cxdx_avp.c:137]: cxdx_get_avp(): cxdx_get_result_code: Failed finding avp Jul 16 14:59:23 cw-aio /usr/sbin/kamailio[31605]: INFO: ims_icscf [cxdx_uar.c:71]: create_uaa_return_code(): created AVP successfully : [uaa_return_code] Jul 16 14:59:23 cw-aio /usr/sbin/kamailio[31605]: ERROR: tm [ut.h:254]: uri2dst2(): ERROR: uri2dst: bad_uri: scscf.epc.mnc004.mcc324.3gppnetwork.org Jul 16 14:59:23 cw-aio /usr/sbin/kamailio[31605]: ERROR: tm [t_fwd.c:1711]: t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches

Purpose of table location_attrs
by mayamatakeshi 16 Jul '15

16 Jul '15

Hello, I need to prepare two kamailio instances accessing the same mysql db. They will write to different location tables so i use function calls like these: Server1: save("k1_location"); lookup("k1_location"); Server2: save("k2_location"); lookup("k2_location"); This is working fine. However, checking db, I can see there is also a table called location_attrs and I am not sure what is its purpose (is this documented?). Anyway, I suspect I should also set a separate copy of it for each kamailio instance, but I am not sure how to do it. Regards, Takeshi

Unclear documentation for "priority" field in Dispatcher module
by Sven Neuhaus 16 Jul '15

16 Jul '15

Hello, the documentation doesn't clearly state if a larger value for the priority field means that it gets used first before entries with smaller priority values are used - or vice versa. It currently states: “8” - select destination sorted by priority attribute value (serial forking ordered by priority). and priority: sets the priority in destination list (based on it is done the initial ordering inside the set) This is just ambiguous. It should clearly say wether the list is processed in ascending or descending order for the priority value when using algorithm 8 (serial forking aka failover). Regards, -Sven Neuhaus

Issue handling SRTP and RTP with rtpproxy and rtpengine
by Alberto Sagredo 15 Jul '15

15 Jul '15

Hi Im using an Asterisk cluster behind Kamailio and some services are running on Asterisk. Traffic always must go to Asterisk so RTPPROXY and RTPNGINE do the work and send traffic to Asterisk and traffic from Asterisk go to RTP Proxy I have been able to get rtpproxy working and later tried RTPengie to be able to manage SRTP I have been able to make SRTP To RTP to Asterisk Im able to call between RTP using rtpproxy as recording is a must and rtpengine does not record yet. But im not able to call between SRTP extensions, i understand also SRTP to RTP would work as im doing with Asterisk (Only the speak SRTP as rtpengine trasncode) I have this code on NATMANAGE but i do not know what could be wrong to handle SRTP Any idea? Thanks in advance if(src_ip==ASTERISK1_LAN || src_ip==ASTERISK2_LAN ){ if (sdp_get_line_startswith("$avp(mline)", "m=")) { if ($avp(mline) =~ "AVP") { add_rr_param(";rtp=AVP-kamtoast"); set_rtp_proxy_set("1"); rtpproxy_manage("rwei"); } if ($avp(mline) =~ "SAVP") { add_rr_param(";rtp=SAVP-kamtoast"); rtpengine_manage("trust-address direction=external replace-origin replace-session-connection ICE=remove RTP AVP"); } } } else{ if (sdp_get_line_startswith("$avp(mline)", "m=")) { if ($avp(mline) =~ "AVP") { add_rr_param(";rtp=AVP-asttokam"); set_rtp_proxy_set("1"); rtpproxy_manage("rwie"); } if ($avp(mline) =~ "SAVP") { add_rr_param(";rtp=SAVP-asttokam"); rtpengine_manage("trust-address direction=external replace-origin replace-session-connection ICE=remove "); } } } If you need any more info let me know.

Attached is captured trace. Clearly BYE is retransmitted a few times, then request for UPDATE is received but it is not possible to answer it because the call is already hung up (as far as I understand). Kamailio routing file is available upon request. Thank you in advance!

ISUP decode and store to be able to append_body_part() later
by andre second 15 Jul '15

15 Jul '15

Hi, I am trying to extract and save ISUP from SIP-I packet for a later use. The problem is that data is stored in binary format and needs decoding before saving to a variable. Can Kamailio perform any decoding so that later I can use append_body_part() to append it back to a multipart message? Thanks,Andrei

Issues with Yealink SDP and sdp_with_transport()
by Alberto Sagredo 14 Jul '15

14 Jul '15

Im using if(sdp_with_transport("RTP/SAVP")) to detect with endpoint is send SAVP or not to divert to and rtp proxy or rtpengine, as you know rtpproxy supports recording and rtpengine does not yet. So when using if(sdp_with_transport("RTP/SAVP")) with Grandstream Phones all worked fine, but when configuring Optional or Compulsory SRTP in Yealink it seems to do not detect i have seen that crypto lines are not in the final SDP but do not know if thats the reason Did you have a similar issue with Yealink?

Kamailio Load balancing Across Multiple Asterisk Servers -Chanspy
by Jonathan Hunter 14 Jul '15

14 Jul '15

Hi guys, I have a kamailio load balancing requests across 2 Asterisk Servers, and all is working well. Only problem now is when utilizing feature codes to look to listen into calls using the chanspy application I am having issues. I am passing calls to *2222 into Asterisk, where an IVR answers the call, then sends an INVITE back to kamailio to check to see if the extension I want to listen into is in an active call (hash table), and the call will then be forwarded to the Asterisk in question and chanspy applied so it can be listened to. The problem I have is when I send an INVITE from Asterisk Server, and then kamailio sends an INVITE back to the same Asterisk Server I get the following failure in asterisk console; Not accepting call completion offers from call-forward recipient I appreciate its potentially more an Asterisk question but I wondered if anyone had experienced the same issue? I have setup a completely load balanced environment so dont want to use Primary/Secondary Server routing. Thanks Jon

Possible problem with multiple threads handling same SIP message
by Dirk Teurlings - SIGNET B.V. 14 Jul '15

14 Jul '15

Hello, Running kamailio 4.2.5 for a few weeks now, coming from 4.2.3. Since the upgrade we increased the logging substantially in our routing to get more insight into what is going on. We noticed that in a few cases the log showed a SIP message was being threated by multiple forks, each considering if it was a non-existing call. e.g. Jul 9 13:19:32 son-sbc1-dc1 /usr/sbin/kamailio[17170]: INFO: <script>: 28ca767d5524f7ac095efcd02d6995f5@1.2.3.4:5060 - CB, Checking service restrictions Jul 9 13:19:32 son-sbc1-dc1 /usr/sbin/kamailio[17170]: INFO: <script>: 28ca767d5524f7ac095efcd02d6995f5@1.2.3.4:5060 - CB, Checking international restrictions Jul 9 13:19:32 son-sbc1-dc1 /usr/sbin/kamailio[17171]: INFO: <script>: 28ca767d5524f7ac095efcd02d6995f5@1.2.3.4:5060 - CB, Checking service restrictions Jul 9 13:19:32 son-sbc1-dc1 /usr/sbin/kamailio[17171]: INFO: <script>: 28ca767d5524f7ac095efcd02d6995f5@1.2.3.4:5060 - CB, Checking international restrictions As you can see this shows different threads handling the exact same callid (printed by $ci). And both run the same checks in our routing plan. The main problem is, I'm not able to reproduce this on the testplatform, but only see it happen on the main systems. Also, it doesn't happen that often, in this case there are about maybe 10 similar calls like this over the run of a few weeks. This case show the call being handled by 2 threads, but we've even seen with one call it being handled by 4 threads, all with the same $ci and the same messages, just different PIDs. I've checked and made sure the routing isn't recursively calling itself. But even if that was true, I would imagine the same PID for all the log entries. Running production in debug mode isn't an option, as it will interfere too much with the day-to-day business. So I'm hoping to get a few pointers here maybe, I'm happy to look at the source code more in depth, I just need a little help in the right direction to not get lost in other code. Any help is much appreciated. Cheers, Dirk

Kamailio as pass through proxy
by kai.ohnacker＠cbc.de 14 Jul '15

14 Jul '15

Hello, I try to setup a SIP infrastructure with Kamailio server in private network and a pass through Kamailio proxy in the DMZ for NAT handling. (-> TEST.jpg) The pass through proxy uses a new routing algorithm and this works fine for external calls to internal calls. (->Kamailio.cfg.txt) The logic behind is if a packet on external interface arrives, the proxy change the URI and forward the packet to the internal SIP server. Otherwise, the proxy shall forward the packet to external interface if a packet arrives at the internal interface. Because the SIP server has a fix IP, it's easy to route to this server, but the way back is more complicated and I think my algorithm is not working. But the first problem is the routing behavior from the private server if I try to make a call from intern to extern. The server sends the request to the external IP address from the client and the IP address from the pass through Kamailio proxy is not considered. 8(2720) ERROR: <core> [udp_server.c:576]: udp_send(): sendto(sock,0x7f4724dd9238,1328,0,192.168.1.20:5060,16): Network is unreachable(101) 8(2720) ERROR: tm [../../forward.h:208]: msg_send(): udp_send failed 8(2720) WARNING: tm [t_fwd.c:1610]: t_send_branch(): ERROR: t_send_branch: sending request on branch 0 failed 8(2720) exec: *** cfgtrace:request_route=[RELAY] c=[/usr/local/etc/kamailio/kamailio.cfg] l=553 a=24 n=sl_reply_error 8(2720) ERROR: sl [sl_funcs.c:387]: sl_reply_error(): ERROR: sl_reply_error used: Unfortunately error on sending to next hop occurred (477/SL) 8(2720) exec: *** cfgtrace:request_route=[RELAY] c=[/usr/local/etc/kamailio/kamailio.cfg] l=555 a=2 n=exit 7(2718) exec: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[/usr/local/etc/kamailio/kamailio.cfg] l=474 a=5 n=route To change the IP address which is used from the private server as the destination address, I added the following lines to the Kamailio.cfg. modparam("registrar", "use_path",1) modparam("registrar", "path_mode", 2) modparam("registrar", "path_use_received",1) modparam("path", "use_received", 1) But the routing behavior has not changed. (perhaps this configure was not the right) Is there a way to configure the private server that the last IP address from the record-route header is used? Cheers, Kai

Removing headers in a failure route on 3xx redirect
by Daniel Tryba 13 Jul '15

13 Jul '15

I'm adding and removing headers in the standard route[RELAY], but if there is a redirection involved headers aren't removed. route[RELAY] { #stdstuff route(ADDCHECKSUM); # enable additional event routes for forwarded requests # - serial forking, RTP relaying handling, a.s.o. if (is_method("INVITE|SUBSCRIBE")) { t_on_branch("MANAGE_BRANCH"); t_on_reply("MANAGE_REPLY"); } if (is_method("INVITE")) { t_on_failure("MANAGE_FAILURE"); } if (!t_relay()) { sl_reply_error(); } exit; } route[ADDCHECKSUM] { if($avp(dst_accountcode) || $avp(src_accountcode)) { #some magic remove_hf("X-rand"); remove_hf("X-csum"); append_hf("X-rand: $var(rand)\r\n"); append_hf("X-csum: $var(checksum)\r\n"); } return; } This works well unless the destination is a redirecting sip server. failure_route[MANAGE_FAILURE] { route(NATMANAGE); if (t_is_canceled()) { exit; } if (t_check_status("3[0-9][0-9]")) { #... route(RELAY); exit; } -user calls destination. -dispatcher sets destination is send to redirectserver and routes to RELAY, addchecksums add some headers called from relay. -redirectserver replies 302. -failure route triggers and ends with a route to RELAY. Any existing old values should be removed and the newer ones added. But end the result is that I have two sets op X-rand/csum headers for the INVITE to the redirection contact. How do I get rid of every X-csum/rand header except the last added ones? Version tested: 4.2.5.

Pipelimit
by Fred Posner 13 Jul '15

13 Jul '15

I know in ratelimit, you can define a method within queues... for example, modparam("ratelimit", "queue", "3:INVITE") to match on INVITE method. With pipelimit, is the method called from the config, such as: if(is_method("INVITE")) { # Checking limit on INVITE if (!pl_check("$au", "traildrop", "$var(limita)")) { pl_drop(); exit; } } if(is_method("REGISTER")) { # Checking limit on REGISTER if (!pl_check("$au", "traildrop", "$var(limitb)")) { pl_drop(); exit; } } -- Fred Posner The Palner Group, Inc. http://www.palner.com (web) +1-503-914-0999 (direct)

msilo delete rows

Hi All, I'm fighting with msilo module now. I recive an offline message, but msilo gets 408 status and think that a message wasn't sent succesfully. According to the log, the error somewhere in t_relay, but I couldn't find where exactly. Therefore, msilo doesn't delete rows from silo table in database and everytime the user reregisters he gets offline messages again and again. -- lifayk e: lifayk(a)gmail.com pgp: 0x84CAC40B

sctp on Centos 7
by micunek＠gmail.com 13 Jul '15

13 Jul '15

Hi, I would like to enable and use sctp in kamailio but I do not know exactly how to do it. It seems that documentation is a little bit inconsistent. 1. I have Centos 7 and kamailio installed from repositories. 2. I set loadmodule "sctp" in kamailio.cfg 3. I got this error: Jul 9 08:08:54 kamailio: : sctp [sctp_mod.c:99]: mod_register(): sctp core support not enabled Jul 9 08:08:54 kamailio: ERROR: <core> [sr_module.c:600]: load_module(): /usr/lib64/kamailio/modules/sctp.so: mod_register failed Jul 9 08:08:54 cw-aio kamailio: : <core> [cfg.y:3432]: yyerror_at(): parse error in config file /etc/kamailio_pcscf/kamailio.cfg, line 230, column 12-17: failed to load module 4. I checked mod_register() function and found out that USE_SCTP should be set. 5. kamailio -V did not show USE_SCTP 6. Next I tried to compile kamailio sources from 4.3 branch make include_modules="db_mysql tls sctp" SCTP=1 cfg make all 7. Still the same problem "mod_register(): sctp core support not enabled" 8. Then I added USE_SCTP to C_DEFS and compile again. This attempt was successfull. I was able to see USE_SCTP in kamailio -V output. Questions: 1. What is the right procedure to enable sctp in kamailio? 2. Why the -DUSE_SCTP was not used when SCTP=1 was used. According to documentation: "The core Makefile variable SCTP must be set to 1 (which is by default set to 1 in Makefile.defs) and sources compiled with -DUSE_SCTP (automatically set when SCTP=1). In other words, if core Makefiles are not changed and SCTP variable is not overwritten from command line, then the SCTP support in core is enabled." Regards, Peter

pua_publish MWI message via xmlrpc

Hi All, I am having difficulty getting pua_publish to issue a NOTIFY when I send an XMLRPC command to generate a PUBLISH into the presence server.

I have an XML file which is the basis of the XMLRPC request via curl, I have attached it to this email for you to view, please would you take a look and let me know where I am going wrong, I suspect it is my message body as the pua module complains about the message body being NULL: Jul 10 17:27:40 reg01 /usr/sbin/kamailio[7736]: ERROR: pua [add_events.c:125]: pres_process_body(): while parsing xml memory Jul 10 17:27:40 reg01 /usr/sbin/kamailio[7736]: ERROR: pua [send_publish.c:650]: send_publish(): while processing body Jul 10 17:27:40 reg01 /usr/sbin/kamailio[7736]: ERROR: pua [send_publish.c:652]: send_publish(): NULL body Jul 10 17:27:40 reg01 /usr/sbin/kamailio[7736]: ERROR: pua_mi [mi_func.c:290]: mi_pua_publish(): sending publish failed Kamailio verion is "version: kamailio 4.3.0 (x86_64/linux) c6aa95" I can issue other XMLRPC commands, urloc lookups method lists and those work, I just cant see where I am going wrong with this one.

dmq/dmq_userloc crash on startup (kamailio 4.3.0)

Hi All, Another thing I noticed while playing with kamailio and dmq/dmq_usrloc is that 7 out of 10 times the kamailio process crashes when I initially start it up. Any tips/requests for further debugging would be greatly appreciated.

dialog: use keepalive & timeout features together
by Andrey Utkin 09 Jul '15

09 Jul '15

Would be nice if it would be possible to - make timer of "default_timeout" reset to 0 when keep-alive reply is received from remote part of call leg, so that the timeout expires (triggering call termination) only if some call party gets offline (we don't want just to limit the duration of normal call, even if call parties don't send any new SIP requests); OR - make unresponsiveness of call parties to keep-alive messages (controlled with ka_timer, ka_interval parameters) lead to some action, like call termination. Please advise if I miss something, and how to implement this better. Thanks in advance. -- Andrey Utkin

Moving from haproxy to db_cluster
by Jan Hazenberg 09 Jul '15

09 Jul '15

Hi, I have a question about the db_cluster module. We are currently using a galera mysql cluster from severalnines, in this setup haproxy is installed on the kamailio nodes handling the database failover. The question is if a database node fails and the TCP connection breaks the sql query will probably fail when using haproxy since it is not aware of the query. Will the db_cluster module send the query to the next available mysql node in the cluster without a failing query? If thats the case i should not notice the failing dbnode in my kamailio script. In other words, will there be a advantage in using the db_cluster module instead of haproxy? Thanks, Jan Hazenberg

Hello, I'm using the function sdp_remove_codecs_by_id from sdpops module in order to remove some codecs in INVITE request before send it to freeswitch, but the function doesn't remove the codec, and it doesn't give any error message.

MetaSwitch ignores Contact: header
by Markus 08 Jul '15

08 Jul '15

Dear list, I'm running kamailio-4.2.3-3.1.x86_64 in a very simple setup: one Asterisk server behind kamailio. But I'm using dispatcher, the other servers are just down currently. :) Different vendors route DIDs to kamailio's IP and kamailio handles the communication towards Asterisk. Now I have a new vendor who uses MetaSwitch, and there is a problem. All calls get dropped with a BYE from the Asterisk side after 32 seconds because Asterisk never receives the ACK, because kamailio doesn't forward it, because MetaSwitch sends it as ACK sip:number@KAMAILIO-IP instead of ACK sip:number@ASTERISK-IP That means MetaSwitch ignores what we tell it in the Contact: header. Is this MetaSwitch'es "fault" or kamailio's? All other vendors work fine without problems. Therefore I have compared an "old" vendor and the new one. Here is the result that shows the difference: Old vendor - works: OLDVENDOR-IP.5060 > KAMAILIO-IP.5060: INVITE sip:number@KAMAILIO-IP KAMAILIO-IP.5060 > OLDVENDOR-IP.5060: SIP/2.0 100 trying KAMAILIO-IP.5060 > ASTERISK-IP.5060: INVITE sip:number@KAMAILIO-IP ASTERISK-IP.5060 > KAMAILIO-IP.5060: SIP/2.0 100 Trying ASTERISK-IP.5060 > KAMAILIO-IP.5060: SIP/2.0 200 OK KAMAILIO-IP.5060 > OLDVENDOR-IP.5060: SIP/2.0 200 OK OLDVENDOR-IP.5060 > KAMAILIO-IP.5060: ACK sip:number@ASTERISK-IP:5060 KAMAILIO-IP.5060 > ASTERISK-IP.5060: ACK sip:number@ASTERISK-IP:5060 New vendor with MetaSwitch - doesn't work: NEWVENDOR-IP.5060 > KAMAILIO-IP.5060: INVITE sip:number@KAMAILIO-IP:5060 KAMAILIO-IP.5060 > NEWVENDOR-IP.5060: SIP/2.0 100 trying KAMAILIO-IP.5060 > ASTERISK-IP.5060: INVITE sip:number@KAMAILIO-IP:5060 ASTERISK-IP.5060 > KAMAILIO-IP.5060: SIP/2.0 100 Trying ASTERISK-IP.5060 > KAMAILIO-IP.5060: SIP/2.0 200 OK KAMAILIO-IP.5060 > NEWVENDOR-IP.5060: SIP/2.0 200 OK NEWVENDOR-IP.5060 > KAMAILIO-IP.5060: ACK sip:number@KAMAILIO-IP:5060 ASTERISK-IP.5060 > KAMAILIO-IP.5060: SIP/2.0 200 OK KAMAILIO-IP.5060 > NEWVENDOR-IP.5060: SIP/2.0 200 OK NEWVENDOR-IP.5060 > KAMAILIO-IP.5060: ACK sip:number@KAMAILIO-IP:5060 ASTERISK-IP.5060 > KAMAILIO-IP.5060: SIP/2.0 200 OK KAMAILIO-IP.5060 > NEWVENDOR-IP.5060: SIP/2.0 200 OK NEWVENDOR-IP.5060 > KAMAILIO-IP.5060: ACK sip:number@KAMAILIO-IP:5060 ... and so on ... Can I do something about this or is a change on MetaSwitch'es side in order? Thank you! Markus

BYE request with Sipp refused
by Loic Chabert 08 Jul '15

08 Jul '15

Hello everyone, I'm a newbie in kamailio world and make some tests to dispatch call over several asterisk instances. This part works, my call has been distributed over two instances (if i make a call with jitsi for example). Now, i want to test performance of my cluster and use Sipp to chalenge it. All method is working fine, except the BYE method, where kamailio send me back a 404 Not here. This is my SIPP scenario: ... <pause/>  <send retrans="500"> <![CDATA[ BYE sip:[service]@[remote_ip] SIP/2.0 Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch] From: sipp <sip:sipp@loicchabert.fr>;tag=[pid]SIPpTag00[call_number] To: sut <sip:[service]@[remote_ip]:[remote_port]>[peer_tag_param] Call-ID: [call_id] CSeq: 2 BYE Contact: sip:sipp@[local_ip]:[local_port] Max-Forwards: 70 Subject: Performance Test Content-Length: 0 ]]> </send> ... I use the classic file of kamailio, with some adjustement for dispatching. Any ideas concerning this problem ? This BYE is not in transaction so he is drop by kamailio ? Thank in advance, Regards.

CNXCC cnxcc_set_max_time Version 4.2
by Jonathan Hunter 08 Jul '15

08 Jul '15

Hi Guys, I have just moved from kamailio 4.1, to 4.2 and have installed via git version 4.2 I am testing with the function cnxcc_set_max_time, as I want to set the maximum call duration. Having moved to 4.2, i cant get the module to terminate the call. I have set dlg_flag, and cc_flag, following examples on the wiki but I cant get it to work. Does anyone have any suggestions for me please? My same code on 4.1 works ok. Thanks Jon

Potential ip_addr_match_net bug
by Kyle Kurz 07 Jul '15

07 Jul '15

I'm using allow_address function of the permissions module and I'm seeing strange behavior with network masks not divisible by 8. I have 172.16.0.0/12 in my address table and Kamailio is marking packets from 172.56.16.232 as being part of that local subnet. If I change the subnet to 172.16.0.0/16, I no longer have an issue. I know there was a bug several years ago related to this ( http://git.kamailio.org/gitlist/index.php/sip-router/commit/0ead7ab31bf0df6…), but that code is very different, so I'm wondering if a regression has crept in? I'm using Kam 4.1.6.

dmq_replicate deserializing?
by Asgaroth 07 Jul '15

07 Jul '15

Hi All, I am playing with the new dmq_replicate module and am banging my head against an issue I have come accross. I can see the kamailio registrars sending the replication messages to the other node(s) in the dmq bus, and the payload looks to be of type json. However, on the recieving nodes, when I try to issue a kamctl ul show --brief, the output of the AOR's are garbled. I had a look at the dmq/dmq_ursloc moduled, and the dmq module docs mention that we may need to load our own deserializers, is this the case when using the dmq_usrloc module as well? I am only using dmq to replicate registration messages. Here is a sample of the dmq workers on a recieving node applying the update, and you can see that it thinks the contact to add is 'p÷#031#002', is was expecting the actual AOR of the subriber to show up here. Am I missing something simple here or is there something more sinister at play. Any pointers would be greatly appreciated.

IMS server with a core network
by test testt 07 Jul '15

07 Jul '15

hello, I posted a message in the kamailio forum but it wasn't in the good place, so I rebroadcast at this e-mail as it was say. Hello, I have installed Kamailio 4.2 and I would like to use it as IMS server but I don't have any ideas how to do this. I have a LTE core network which includes HSS ans PCRF. I saw on this page ( http://www.kamailio.org/w/2013/05/ims-kamailio/ ) that is apparently easy, just need to take the P-CSCF, S-CSCF and I-CSCF Kamailio and Diameter config files in the examples folder and run kamailio but I don't know how to use them and I didn't find any tutorials about it. Could you help me please ? Marc link: https://github.com/kamailio/kamailio/issues/227#issuecomment-118073500 I tried the 2 tutorials that it has given but it's not really working I am using ubuntu 15.04 Thanks Marc

Dispatcher, Failure Route and fr_timeout
by Asgaroth 07 Jul '15

07 Jul '15

Hi All, I would like to reduce the time it takes for kamailio to timeout an initial message to a dispatcher destination so that it will select the next destination in the set, before, hopefully, a restransmission. In this case I am testing registration messages. I came accross the t_set_fr() function in the TM module documentation today and have been experimenting with it for some hours. I have an issue where a 408 timout is sent back to the UAC before the last destination in the dispatcher set is selected, I suspect I am hitting the timeout somewhere, but I cannot see where, I presume the fr_timeout is set every time I issue the t_set_fr() call and the associated t_relay. I'm just wondering if I am doing this correctly, if one of the guru's out there wouldnt mind casting an eyeball over this config and let me know if I am on the right track, or if I am going about this in the wrong way. Any suggestions are most welcome. What appears to be happening is, I have 3 destinations in the dispatcher set, it looks like the 1st 2 are tried, which correctly timeout and are set inactive-probing, but on the last destination, which is working, I appear to be getting a 408 timeout being sent back from kamailio. Here is a snip of my configuration: #!define NO_RESPONSE_TIMER 250 request_route { t_on_failure("DISPATCHER_FAILURE"); t_set_fr(0, NO_RESPONSE_TIMER); if(!ds_select_dst("1", "0")) { xlog("L_ERR", "No dispatcher destinations available for $ru\n"); sl_send_reply("500", "No destination available"); exit; } route("RELAY") } route[RELAY] { if (!t_relay()) { sl_reply_error(); } exit; } failure_route[DISPATCHER_FAILURE] { if (t_is_canceled()) { exit; } # select next destination only for local timeout if (t_branch_timeout() && !t_branch_replied()) { xlog("L_INFO", "route[DISPATCHER_FAILURE] : $rm : timeout and no reply ($si:$sp->$Ri:$Rp->$du)\n"); xlog("L_INFO", "route[DISPATCHER_FAILURE] : $rm : setting $du to probing state"); ds_mark_dst("ip"); if(ds_next_dst()) { xlog("L_INFO", "route[DISPATCHER_FAILURE] : $rm : next destination selected ($du)\n"); t_set_fr(0, NO_RESPONSE_TIMER); t_relay(); exit; } else { xlog("L_INFO", "route[DISPATCHER_FAILURE] : $rm : No destinations available for $rd"); send_reply("500", "No destination available"); exit; } } }

clarification on tcp keepalive
by Kelvin Chua 07 Jul '15

07 Jul '15

using kamailio 4.3 on ubuntu server 14.04 i noticed tcp socket will be killed by kamailio after around 11 minutes with or without tcp_keepalive=no. tcpdump shows that by default (tcp_keepalive=yes) there is indeed keepalive packets going back and forth. if set to no, there would be nothing in between. if i have clients who have registration timeout of 1700, they would send re-registration around half of that, or around 14 minutes after registration. then the socket would be long dead and they would be unreachable for 3 minutes. based on procfs, ubuntu have settings for 9 probes with 75 seconds interval so that means around 11 minutes of sending keepalives. so i tried changing these values, on procfs. and tried playing around with these kamailio cfg settings as well: tcp_keepcnt tcp_keepidle tcp_keepintvl whatever i do, the interval between keepalives are always 2 minutes and after 4-5 probes, kamailio will send a FIN to the client. i checked the source code tcp_main.c and it looks alright. could this be an ubuntu issue? anybody seen this before? I created a workaround by setting expire 900 for all registrations but this is not ideal. Kelvin Chua

DIAMETER based on TCP requires a FIXED I/S-CSCFSOURCE PORT in order to make Cx work towards a External HSS
by Jan Devai 07 Jul '15

07 Jul '15

Hi experts, from the current trace we can see that the I/S-CSCF always changes SOURCE port when contacting our eternal HSS. In order to make the Cx work HSS expects the Source port to be fixed on the TCP layer and in our I/S-CSCF configuration we did not find any setting for SOURCE Port. Can somebody help us please ;-) ? We appreciate your support, Br, Jan

mongodb and jansson

when using mongodb with jansson, intermittent failures will be seen because jansson would change the order of keys inside a json object. mongodb would expect the first key to be a command, for example "insert". this is disastrous! below is a fix for jansson which will preserve the order on which the json object was created. --- modules/jansson/jansson_utils.c.old 2015-07-06 17:41:25.852770681 +0800 +++ modules/jansson/jansson_utils.c 2015-07-06 17:42:27.384769579 +0800 @@ -33,7 +33,7 @@ val->flags = 0; if(json_is_object(v) || json_is_array(v)) { - const char* value = json_dumps(v, JSON_COMPACT); + const char* value = json_dumps(v, JSON_COMPACT|JSON_PRESERVE_ORDER); *freeme = (char*)value; val->rs.s = (char*)value; val->rs.len = strlen(value); Kelvin Chua

subst + insert_hf issue
by Igor Potjevlesch 03 Jul '15

03 Jul '15

Hello, I'm doing a subst on the From header for some particular cases, like this one: subst('/^(From|f):(.*)<sip:(.*)@/\1: "Anonymous" <sip:\3@/g'); In the same route (REQUEST_ROUTE called "INVITE"), I do the following: insert_hf("X-CarrierName: $avp(s:carrier_id)\r\n"); For many User-Agent, the X-CarrierName header is inserted after the @ into the user part of the From. So the From: looks like this: From:"Anonymous" <sip:0123456789@X-CarrierName: ABCDE\r\n The domain name part of the From is on the next line: <domain>:5060>;tag=3fdce0-a658bfa-13c4-50029-55941ccd-5eab9369-55941ccd\r\n I can't reproduce. The only potential explanation is that this impact the User-Agent that have the From at the top of the headers. If someone know what could going wrong here. Regards, Igor

Diameter sorce/destination port

Hi All, I am trying to use Cx (Diameter) interface via TCP towards our HSS according to Carsten Bock example. However kamailio client obtain TCP RST from HSS because a kamailio source port is different than port where kamailio is listen. I do not know if this is Diameter/Cx requirement or not. I did not find it in specifications. Is there any way how to ensure that kamailio use same port number for source and destination (3869)?. <?xml version="1.0" encoding="UTF-8"?> <DiameterPeer FQDN="...3gppnetwork.org" Realm="...3gppnetwork.org" Vendor_Id="10415" Product_Name="CDiameterPeer" AcceptUnknownPeers="1" DropUnknownOnDisconnect="1" Tc="30" Workers="4" QueueLength="8" TransactionTimeout="5" SessionsHashSize="128" DefaultAuthSessionTimeout="3600" MaxAuthSessionTimeout="3600" > <Peer FQDN="hss....3gppnetwork.org" Realm=".3gppnetwork.org" port="3868"/> <Acceptor port="3869" /> <Auth id="16777216" vendor="10415"/>  <Realm name="....3gppnetwork.org"> <Route FQDN="hss...3gppnetwork.org" metric="10"/> </Realm> <DefaultRoute FQDN="hss.....3gppnetwork.org" metric="10"/> </DiameterPeer> Thanks Peter

Problem Storing USRLOC Additional Attributes
by Luca Mularoni 02 Jul '15

02 Jul '15

Hi All, I'm using kamailio 4.2.5 (compiled from source and aligned up to commit [00a36ae07c587992d6486277ce2e9ae6c009685f]). In order to enrich users data collected during registering phase, I would like to store them in USRLOC Additional Attributes through the use of 'xavp_contact' structure, but I'm having problems storing them. Below relevant chunks of config: ... # ----- usrloc params ----- modparam("usrloc", "db_mode", 2) modparam("usrloc", "use_domain", 0) modparam("usrloc", "xavp_contact", "ulvals") ... route[REGISTRAR] { ... # Just an example $xavp(ulvals=>A) = "A"; $xavp(ulvals[0]=>B) = "B"; $xavp(ulvals[0]=>C) = "C"; $xavp(ulvals[0]=>D) = "D"; ... if (!save("location")) sl_reply_error(); exit; } route[LOCATION] { ... if(!lookup("location") { # Handle Failure ... } # Print USRLOC Additional Attributes # Just an Example $var(i) = 0; $var(N) = $branch(count); while($var(i)<=$var(N)) { xlog("LOC - [$var(i)] - A [$xavp(ulvals[$var(i)]=>A)]\n"); xlog("LOC - [$var(i)] - B [$xavp(ulvals[$var(i)]=>B)]\n"); xlog("LOC - [$var(i)] - C [$xavp(ulvals[$var(i)]=>C)]\n"); xlog("LOC - [$var(i)] - D [$xavp(ulvals[$var(i)]=>D)]\n"); $var(i) = $var(i) + 1; } ... } And this is the relevant chunk of syslog when a local subscriber is found in 'location' table: ... LOC - [0] - A [A] LOC - [0] - B [<null>] LOC - [0] - C [<null>] LOC - [0] - D [D] ... Summing up, it seems that when xavp structure is stored in memory, just first and last elementsare inserted. In real config I'm using more than 4 attributes and behaviour is the same: just first and last are stored. I've tried also with modparam("usrloc", "db_mode", 0) but the problem remains. Where I'm wrong in using this structure? Or it could be a bug? Thank You in advance for your help Luca Mularoni

Hello everybody, My SIP vendor request me to replace FROM before sending the traffic. In order to achieve this I use uac_replace_from. UAC module is setup in restore_mode = auto. In my insfrastructure I have an Asterisk and then a Kamailio that connects to vendor via internet. Softphone -> Asterisk -> Kamailio -> Internet -> SIP vendor If caller ID is setup in Asterisk using CALLERID(num)=34888888888 and then INVITE is forwarded to Kamailio, the call is established and finished correctly but the URI in TO field in BYE request from Kamailio to Asterisk contains garbage. In the scenario the callee hangs up the call. Example of TO Field with garbage: 34888888888 <sip:50026896@no{soy,ns^^> What I do see is that the number "50026896" that is part of the URI is the same I use in: uac_replace_from("50026896", "sip:50026896@sip.vendor.es"); Something else that I have found is that vsf field is the same in the INVITE and in the BYE. ---------------------------------------------------------------------------------------------------------------- 2015/06/23 17:48:38.552442 192.168.0.2:5060 -> 192.168.0.1:5060 BYE sip:34888888888@192.168.0.1:5060 SIP/2.0 Via: SIP/2.0/UDP 192.168.0.2;branch=z9hG4bKfb49.73c6517609cdb6f7ec00b1f40a05dbe9.0 Via: SIP/2.0/UDP 8.8.8.8.8;rport=5060;branch=z9hG4bKfcdf.3767c59c2d0e3d8ab695669845ce4cea.0 branch=z9hG4bK04boo6104o5hcso0c2a1sd0000g00.1 Call-ID: 4bf8effb45b0ae8e049366297924cbba@192.168.0.1:5060 From: <sip:28999999999@192.168.0.2;tag=k0eci3x3-CC-30 To: 34888888888 <sip:50026896@no{soy,ns^^>;tag=as041b7d84 CSeq: 1 BYE Reason: Q.850;cause=16;text="normal call clearing" Max-Forwards: 67 Content-Length: 0 ------------------------------------------------------------------------------------------------------------------ DEBUG: uac [replace.c:525]: restore_uri(): getting 'vsf' Route param DEBUG: uac [replace.c:533]: restore_uri(): route param is 'AAAAAAEECQkCAgsNAXBeL0NGQUsfVl02Ni44Mw--' (len=40) DEBUG: uac [replace.c:607]: restore_uri(): decoded uris are: new=[sip:50026896@no{soy,ns#005#007] old=[sip:34888888888@8.8.8.8] DEBUG: uac [replace.c:525]: restore_uri(): getting 'vst' Route param DEBUG: uac [replace.c:533]: restore_uri(): route param is 'AAAAAAQPAw8MDgsAAHZBKRVdAhoVHQ4XH1BdYWJhbnRlLmVz' (len=48) DEBUG: uac [replace.c:607]: restore_uri(): decoded uris are: new=[ sip:28999999999@192.168.0.1] old=[sip:999999999@sip.vendor.es] -----------------------------------------------------------------------------------------------------------------------------------

Kamailio no recieved 480/486 messages
by Yuriy Gorlichenko 01 Jul '15

01 Jul '15

At my confiig I have route like this onreply_route[REPLY_FROM_WS] { if(status=~"[12][0-9][0-9]") { xlog("L_INFO", "Manage_Reply from webrtc client {$si:$sp} for method {$rm}: $rs"); rtpengine_manage("force trust-address replace-origin replace-session-connection DTLS=passive ICE=remove RTP/AVP"); route(NATMANAGE); } } This route successfully handling replies 180 183 and 200 and then (after natmanage route) resend to mediaserver. When callee client reject call it send 480 ot 486 message that not resended by kamailio nowhere. First of all I thought that 480 and 486 replies are failure replies but at log I see its at onreply route. So Ok . I added this to onreply_route if (status=~"48[06]"){ xlog("L_INFO", "Manage_Reply from webrtc client {$si:$sp} for method {$rm}: $rs"); rtpengine_manage("force trust-address replace-origin replace-session-connection DTLS=passive ICE=remove RTP/AVP"); route(NATMANAGE); } But message just going through natmanage route and goes nowhere My NATMANAGE route is xlog("L_INFO","NATMANAGE reply {$rm}"); if (is_reply()) { if(isbflagset(FLB_NATB)) { add_contact_alias(); } xlog("L_INFO","reply {$rm}"); } I see at my log only first NATMANAGE xlog... no more... thnks for answer

dialog flags vs dialog variables vs dialog profiles
by Muhammad Shahzad 01 Jul '15

01 Jul '15

Hi, Lasting night i was doing some tests and identified a strange behavior from dialog module. I am using Kamailio v4.3.0 rev. c6aa95. I basically wanted to identify if an incoming sequential ACK (from caller for an answered call) or a BYE (from callee who wants to hangup the call) belong to an existing dialog. First I tried to use dialog profiles as they were already enabled in my kamailio.cfg for every call. Calling the function "is_in_profile" after loose_route in WITHINDLG route, does not works for ACK, but works for BYE. Then I added dialog flags to initial INVITE (using function "dlg_setflag") and check them for ACK and BYE after loose_route (using "dlg_isflagset" method), i have the same behavior. They worked/matched only for BYE, not for ACK. Lastly I set dialog variables (e.g. dlg_var(my_call) = "1") in initial INVITE and checked for them for ACK and BYE requests after loose_route. Only they worked perfectly, i.e. i can match them for both incoming ACK and BYE requests. Is this correct and expected behavior? Why dialog profile and flags do not match for a dialog in unconfirmed state (i.e. ACK from caller after successful call answer)? They only work for confirmed dialogs (e.g. BYE from callee).On the other hand, dialog variables seems to work everywhere (i.e. all sequential requests). Thank you.

Fwd: websocket devices keepalive not working
by Yuriy Gorlichenko 01 Jul '15

01 Jul '15

As I read at README to Nathelper it may not work with usrloc table, Is it write? now I use NAT traversal module and Websocket module to keepalive mechanisms, that uses UDP or WS. with UDP it is wery simple method - OPTIONS replies. With WebSocket module keepalive mechanism uses thomething else. Not a SIP methods, I see at TCPDUMP packets that marks with modparam("websocket", "ping_application_data", "WebSockets rock") I need to handle replies of keepaliwe mechanism.

websocket devices keepalive not working
by Yuriy Gorlichenko 30 Jun '15

30 Jun '15

I try to send keepalive requests (options) to clients at usrloc I tried 4 mechanisms 1) nathelper modparam("nathelper", "sipping_method", "OPTIONS") modparam("nathelper", "natping_interval", 15) modparam("nathelper", "ping_nated_only", 0) modparam("nathelper", "sipping_bflag", 7) modparam("nathelper", "sipping_from", "sip:pinger@mydomain") but it didn't send keepalives to noone client 2)nat_traversal I tried to trigger keepalives with nat_keepalive() when REGISTER coming to my service It works fine with UDP packets modparam("nat_traversal", "keepalive_interval", 15) modparam("nat_traversal", "keepalive_method", "OPTIONS") modparam("nat_traversal", "keepalive_from", "sip:pinger@mydomain") modparam("nat_traversal", "keepalive_state_file", "/var/run/keepalive_state") 3)So I also tried to do it with WebSocket keepalive mechanism, but it still not work for (off course I checked only WS devices) modparam("websocket", "keepalive_mechanism", 15) modparam("websocket", "keepalive_timeout", 15) modparam("websocket", "keepalive_interval", 15) 4) I tried to do it with tcpops Only for ws and tcp (WS is use TCP as i know) tcp_keepalive_enable("15", "5", "15"); same result... So I need mechanism to check all devices for keepalive. I think nathelper works with all protos (As I read at docs) Can somebody explain to me what I doing wrong?

Hello, after some trying with SEMS and Blox as SBC, I changed my idea of SIP infrastructure from Kamailio (private) -SBC in DMZ (Private & Public) - www (Public) to Kamailio (private) - Kamailio with rtpproxy in DMZ (Private & Public) - www (Public). Now, my questions are: How can I connect 2 Kamailio SIP server together? Which modules I need? Is there somewhere a good howto? Cheers, Kai Ohnacker

BYE from CANCLEd path gets forwarded to caller
by Daniel Tryba 30 Jun '15

30 Jun '15

I was testing a scenario whith parallel forking (multiple registers) where 2 endpoints answer near simultaniously. When phone that was just a bit slower hangs up, the BYE gets forwarded to the caller and thus the connection is terminated. This is as far as I know for stateful transactions (t_relay()) I always assumed in this scenario the state machine in kamailio would prevent this kind of behavior by itself. Is there a way to prevent these messages being forwarded?

The server has multiple IPs, but Kamailio is bound to only one address: http://view.xscreenshot.com/9dfdf449a387bdc6f9a719eae3620416 *Sometimes* it answers back from a wrong IP address, here is the proof: http://view.xscreenshot.com/ac661d6b303eda6653b37be7cf65aa65 The interesting thing is that if I do: root@tralab-route-01:~# ip ro get 10.121.24.51 10.121.24.51 via 10.121.43.30 dev vlan486 src 10.121.43.17 cache ipid 0x05ad root@tralab-route-01:~# So the 10.121.43.17 IP is selected, but I *do* expect that Kamailio send back the answer from the same socket where it got the request. What could be the issue ? Why does it do that *sometimes* ? In the majority of the time it works well.. I am not sure why this happens... Thanks, Mitya

don't fragment flag in rtpengine request
by Juha Heinanen 27 Jun '15

27 Jun '15

i was wondering why sometimes requests to rtpengine don't get through and icmp unreachable destination error message is received. it turned out that in these error cases ip packet containing the rtpengine request has 0x02 (don't fragment) flag set even when the packet was bigger than 4 KB. in this case kamailio was running in an amazon container which may be doing something weird. is it somehow possible from the application (= kamailio) to control setting of that flag? -- juha

limit calls to incoming only?
by Peter Villeneuve 26 Jun '15

26 Jun '15

Hi, Is it possible for Kamailio to restrict certain users (like in a group) to only receive calls but never dial out or send SIP Simple messages outbound, while allowing all other "regular" users to make outgoing calls and text messages as well as receive them? If so, which module do you guys recommend I look into? Cheers, Peter

fix_nated_contact NAT rtpproxy problems
by Vik Killa 25 Jun '15

25 Jun '15

Hello, We are trying to get Kamailio working as an SBC using rtpproxy(); The config seems to work except with some carriers, kamailio does not recognize the ACK because it does not match the contact header of the OK I've been trying to figure out how to get kamailio to send the OK back using the public IP address but I cannot figure out how. I've tried using various deployments of the nathelper module such as fix_nated_contact() set_contact_alias() No matter what though, Kamailio will not change the contact header it receives from FS before sending it back to the carriers. This has become frustrating as I read tutorials that showed this is possible, yet I am unable. Thank you. /V

25 Jun '15

Hello, I have developed a Kamailio module to handle group messaging and am using certain functions from the libm.so library. Compilation happens fine, but Kamailio subsequently fails to start because the math.h symbols are unlinked/undefined. Could someone please suggest a workaround for this. Thanks, Shouvanik.

How to disable retransmits via TCP connection? etc.
by Andrey Utkin 25 Jun '15

25 Jun '15

Hi! We meet such an issue with some kinds of client internet connections (e.g. reproduces always on local wifi, but doesn't repr. on 3g inet). We don't know what are exact network characteristics, but what happens from perspective of traffic on SIP server is the following: 1. the SIP client registers successfully to Kamailio (which is recent git master HEAD) with TCP transport for SIP; 2. another client calls this user; 3. Kamailio relays INVITE, it gets transmitted fully and ACK-ed on TCP level; 4. then, within 0.1-0.2 second, Kamailio fires first retransmit of that INVITE, which doesn't get fully transmitted (it is shown trunkated in sniffer output, no TCP ACK replies for it); 5. Kamailio tries to retransmit INVITE again, with the same result as in #5. 6. The caller gets SIP/2.0 408 Request Timeout. A piece of traffic from "ngrep -t -e -d any -W byline port 5060": https://gist.githubusercontent.com/krieger-od/219f9975e5efb980ff5b/raw/096a… The called side app is based on mobile Linphone app. Switching to UDP is not an option (in some networks SIP messages get delivered trunkated which breaks calls), we will check how it works with TLS transport a bit later when there's technical possibility. I have two questions: 1. How would I completely disable retransmissions to TCP connections? 2. Any ideas what can be the reason for this issue? Retransmissions by themselves? -- Andrey Utkin

Kamailio + RTPEngine + Asterisk
by Javier Aristizábal 24 Jun '15

24 Jun '15

Hello folks, I am trying to configure this on the same server: Kamailio v4.2 port 5060 RTPEngine v2.3 port 22222 Asterisk v11.18.0 port 5080 I am follow the Asipto tutorials, for the Kamailio and the real time configuration. Now, I can talk between extension and PSTN without issues. But the trouble is with the Status registration with Asterisk. And I need that Status OK because I am using queues in asterisk for call centre. I got this from with: sip show peers Name/username Host Dyn Forcerport Comedia ACL Port Status Description Realtime 101 (Unspecified) D Yes Yes 0 UNREACHABLE Cached RT the status is UNREACHABLE and the asterisk table sipregs won't update after each registration. To be sure, I tried first all config only with asterisk to check that is not a problem with MySQL or something. On my cfg file I have this for the asterisk registration: route[REGFWD] { if(!is_method("REGISTER")) { return; } $var(rip) = $sel(cfg_get.asterisk.bindip); $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip) + ":" + $sel(cfg_get.asterisk.bindport); $uac_req(furi)="sip:" + $au + "@" + $var(rip); $uac_req(turi)="sip:" + $au + "@" + $var(rip); $uac_req(hdrs)="Contact: <sip:" + $au + "@" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport) + ">\r\n"; if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $hdr(Expires) + "\r\n"; uac_req_send(); } Any clue? Thanks! -- Javier Aristizábal

Kamailio transformation
by Ali Taher 22 Jun '15

22 Jun '15

Hello, Suppose I have $var(a) = 1234#5678 and $var(b)=123455667 I need to get the number before '#' character if exists , meaning that from $var(a) I must get 1234# and from $var(b) I must get empty string. I tried $var(pref)= $(var(a){s.select,0,#}); but I'm getting the whole string if # doesn't exists. There is a way to check if # exists by subtracting the length of the string before and after removing # character and check if length changes , but I want a cost-less method. Any help would be appreciated. Thanks Ali

Capture a Match from Regex comparison
by Sebastian Damm 22 Jun '15

22 Jun '15

Hi, we have some cases, where we get multiple PCMA lines with different numbers from a peer. One of our backend systems doesn't handle that correctly. So what I want to do is detect whether there is a PCMA line with a non-standard number in the SDP. This is how an SDP looks like: v=0 o=hiQ9200 2990220150519102450 1229717573 IN IP4 1.2.3.4 s=Phone Call c=IN IP4 1.2.3.4 t=0 0 m=audio 40174 RTP/AVP 8 0 18 96 97 13 100 98 99 a=rtpmap:8 PCMA/8000 a=fmtp:8 vad=no a=rtpmap:0 PCMU/8000 a=fmtp:0 vad=no a=rtpmap:18 G729/8000 a=fmtp:18 annexb=yes a=rtpmap:96 G726-32/8000 a=rtpmap:97 AAL2-G726-32/8000 a=rtpmap:100 telephone-event/8000 a=fmtp:100 0-15 a=rtpmap:98 PCMA/8000 a=gpmd:98 vbd=yes a=rtpmap:99 PCMU/8000 a=gpmd:99 vbd=yes a=sqn: 0 a=cdsc: 1 image udptl t38 a=sendrecv a=pmft: T38 a=ptime:20 I tried something like that (expecting that the number doesn't change): if (sdp_get_line_startswith("$avp(badcodec)", "a=rtpmap:98 PCMA")) { But this makes Kamailio drop the INVITE when arriving at the line in the config. I guess, "startswith" stops parsing the line at the colon. So I thought I'll make it more generically: sdp_get("$avp(sdp)"); if ($avp(sdp) =~ "a=rtpmap:([1-9][0-9][0-9]?) PCMA") { sdp_remove_codecs_by_id("$missingvariable"); } What I need is to capture the number in the a=rtpmap line so I can delete the codec by ID. But I couldn't find a way to capture the matches from my regex comparison. Am I missing something? (Other approaches for my problem would be welcome, too.) Thanks in advance. Best Regards, Sebastian

Kamailio with Blox SBC (opensips based) - Wrong CSeq
by kai.ohnacker＠cbc.de 22 Jun '15

22 Jun '15

Hello, my setup is a kamailio server as registrar and Blox as SBC. Blox is a freeware GUI with Opensips as framework. Kamailio is located in the private network and Blox operates with 2 NICs (private and public) Now the following problem: If I make a call from public (phonerlite) to private (mayah), the connection don’t reach the “framed” state and is “broken” after 30 sec. After evaluating the log files, I found that the CSeq from Kamailio is wrong. The invite comes from CSeq: 9 INVITE The reply is with CSeq 1 SIP/2.0 180 Ringing Via: SIP/2.0/UDP 192.168.0.3:6060;branch=z9hG4bK38ae.cf317344.0 Max-Forwards: 70 To: <sip:1001@192.168.1.3:8000>;tag=qTKGZvr0ItW From: "PhonerLite" <sip:1000@192.168.1.3:8000>;tag=1005520878 Call-ID: SBCbFgsQn5HcHpEUxJUVF8gQWVZREt6QwJvWVJkXCdAUzdkXl41CUJ4cEdWZV1NQ0tFYQ CSeq: 1 Contact: <sip:1001@192.168.0.33:5060> Record-Route: <sip:192.168.0.1;lr=on> User-Agent: MAYAH 4.9.12.0-2.1.0.45 Content-Length: 0 And here the information from the opensips log files: Jun 22 14:30:32 localhost blox-0-9-6-beta[1975]: ERROR:core:parse_cseq: no method found Jun 22 14:30:32 localhost blox-0-9-6-beta[1975]: ERROR:core:parse_cseq: bad cseq Jun 22 14:30:32 localhost blox-0-9-6-beta[1975]: ERROR:core:get_hdr_field: bad cseq Perhaps someone of you knows this failure or can tell me how to solve this problem?

event_route: what modules/functions are likely to work or not work
by Armen Babikyan 22 Jun '15

22 Jun '15

Hello, With respect to *_route blocks in kamailio configs, I gather that event_route is the newest type of route in the config vocabulary. However, many modules have functions that specifically state that they work within certain routes, like REQUEST_ROUTE and FAILURE_ROUTE, with the implication that they won't work in other routes. For example, there are some functions that "work" in EVENT_ROUTE as well, and that this could be a matter of either documentation not being updated yet, or funny/bad behavior I may encounter at some future point in time... Generally speaking, are there any general statements that can be made about what "common" modules/functions are definitely only available within request_route and onreply_routes? event_route blocks, in particular, elucidate many other use cases for several modules' functions that I'm sure the original authors didn't think of, and it would be great to have a high-level commentary/discussion like "module XYZ or modules that touch A, B, and C don't have a snowball's chance of working in an event_route". Comments are welcome. Thanks! Armen

Port 5061 issue
by Ankhit Vivekananda 19 Jun '15

19 Jun '15

Hello, I have configured kamailio 4.0.4 long back. Now, I wanted to enable the usage of port 5061 with TLS. By doing so, the client(video camera) can place outgoing calls fine. But while receiving an incoming call, the message does not get sent out to the other client. Hence, the call fails. I can place and receive calls on port 5060 successfully without any issues. Can anyone please tell me why port 5061 is giving me a problem. Also, as a test, I set up kamailio on another machine(version 4.1) and 5061 works fine in all directions. Its only on the other machine that I have problems with. Appreciate any help! Thank you, Ankhit

SIP-I trunking
by Jérôme Simionato 19 Jun '15

19 Jun '15

Hello, I'm planning to interconnect kamailio with a SIP-I provider (an i have no more information at this time from my telco). I read the documentation about the SIP-I module, who need to be completed to match our needs. basically, we need to read the location parameter for incoming call, and be able to set redirecting number for outgoing call Does anybody use this module for SIP-I ? Have you experiences of SIP-I trunking with telco ? And another question: when you make an ISUP (SS7) interconnection with a telco, you need to pass specific test to validate the correct implementation of the SS7 protocol (and it's national variant, eg. SPIROU in france). Is it the same thing on an SIP-I interconnection ? Any information about it will be appreciate, Cheers, Jérôme.

SIP Ping a device using Kamailio
by Nelson Migliaro 19 Jun '15

19 Jun '15

Hello, Is there a way to ping a device using Kamailio. In my scenario I need to access a Kamailio located in my DMZ over a firewall that is only open in LAN > DMZ direction. It is close in the other way round. In my current configuration I keep the link open using Asterisk qualify option in SIP. I would like to replace Astersik located in LAN with Kamailio thus I need to keep the link open. I know there is an option using dispatch but I would like to avoid using this module in order to keep it simple. Is there a "simple embedded function" in order to accomplish this. thank you

Dispatcher and options_reply
by jay binks 19 Jun '15

19 Jun '15

Hello, So Im using dispatcher to poll SBC's behind my kamailio load balancer. What I need to do is get a count of how many "active" SBC's there are in the dispatcher module. ( how many SBC's are actively responding to their options ping ) so that I can then use this info when I reply to an OPTIONS on the load balancer. effectively , if there are no SBC's active, the LB needs to not reply to options. I COULD use ds_select_dst or something , but is that going to be overkill from a CPU perspective ? ( And I dont want ds_select_dst to do any modification to my otpions packets ) just wandering what everyone thinks the best way to achieve this would be. -- Sincerely Jay

Hi, I am trying to change only the "display name" of the FROM header using uac_replace_from().However, the value is not being changed (see below) request_route { .... xlog ("L_INFO", "fu=$fu"); uac_replace_from("pbx", ""); xlog ("L_INFO", "fu=$fu"); # authentication route(AUTH); ....} Am I missing anything? Any help in this regard would be greatly appreciated. Thanks,Al

After enabling and deciphering debugging it appears there may be a bug.

It may also be that the issue doesn't occur when find_next_route is called with a valid _hdr which does seem to search for the "next" one vs going straight to the final header in the entire message.

siptrace: how to log sent ACK within dialog

http_query failed to perform curl (28) errors
by Armen Babikyan 17 Jun '15

17 Jun '15

Hello, I am running across the same issue as described here: http://lists.sip-router.org/pipermail/sr-users/2015-February/086796.html Was there a resolution to this issue? I come across this issue fairly regularly. Unlike the OP, however, I do not have any luck by retrying my query: when I place my http_query within a while loop and keep 1-second delays between calls, all consistently fail with error 28. After long pauses, http_query()s start to work as expected. I think that previous thread mentions DNS as a possible culprit. Is http_query using libcurl's preferred resolver, or is it using Kamailio's built-in DNS cache? I really doubt my local resolver is cause of the issue here. Any insight is appreciated. Thanks! Armen

Kamailio Crash

Is it normal for Kamailio to segfault on a duplicate key in the usrloc DB? Jun 15 18:15:23 vproxy2 /usr/sbin/kamailio[13646]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Duplicate entry 'uloc-557a96c1-3577-4e5f1' for key 'ruid_idx' Jun 15 18:15:23 vproxy2 /usr/sbin/kamailio[13646]: ERROR: <core> [db_query.c:337]: db_do_update(): error while submitting query Jun 15 18:15:23 vproxy2 /usr/sbin/kamailio[13646]: ERROR: usrloc [ucontact.c:800]: db_update_ucontact_addr(): updating database failed Jun 15 18:15:23 vproxy2 /usr/sbin/kamailio[13646]: ERROR: usrloc [urecord.c:368]: wb_timer(): updating contact in db failed (aor: sip305_isibmp) I believe that there should never be a duplicate key. I'm not sure how that's happening either. I have 3 Kamailio boxes in a cluster replicating registrations to each other and using a MySQL Galara cluster for the usrloc DB. This is Kamailio 4.0.6. Thanks, Marc

loose_route to find transport=tcp
by Ryan Kendrick 16 Jun '15

16 Jun '15

We are using Kamailio 4.2.5 as a registrar and proxy between many dispersed end-users of a soft phone app and our calling platform / switch. Until now we have used udp exclusively but are trying to introduce tcp between end-users and Kamailio, leaving udp between Kam and our switch...while maintaining the ability for some end-users to use udp to Kam. With some simple address checks I am able to always send to our switch over udp. If all end-users used tcp I could send everything else tcp, but I need to maintain udp support. The specific problem I am having is on a reINVITE such as this one from our platform to the a-leg: INVITE sip:xxxxxx@xxxxxxxxxxxxx:42679;user=phone SIP/2.0 Via: SIP/2.0/UDP xxxxxxxxxxxxx:5060;branch=z9hG4bK218cc8e12ll5035f67INV6a67885312aad Max-Forwards: 35 Route: <sip:xxxxxxxxxxx;lr;r2=on;ftag=daba971c;did=b57.4872;nat=yes> Route: <sip:xxxxxxxxxxx:5070;transport=tcp;lr;r2=on;ftag=daba971c;did=b57.4872;nat=yes> Contact: <sip:xxxxxxxxxx@xxxxxxxxxxxxx:5060> To: "xxxxxx"<sip:xxxxxx@xxxxxxxxxxxxxxxxxxxxxxxxxxx:5070>;tag=daba971c From: <sip:xxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxxxxxxxx :5070>;tag=6a678853-co76461-INS002 Call-ID: MDI4ZmFjNmZhN2Y1NWE2ZTViNTkyZGUwNWE2YzUzYmU CSeq: 7646101 INVITE Allow: INVITE,ACK,CANCEL,BYE,REFER,OPTIONS,NOTIFY,SUBSCRIBE,PRACK,INFO,UPDATE Content-Type: application/sdp Date: Mon, 15 Jun 2015 20:10:18 GMT User-Agent: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Content-Length: 262 As you might notice, we have rr:enable_double_rr set: *There are some situations when the server needs to insert two Record-Route header fields instead of one. For example when using two disconnected networks or doing cross-protocol forwarding from UDP->TCP. This parameter enables inserting of 2 Record-Routes. The server will later remove both of them. * and I believe it is necessary to keep this way. Without it Kamailio doesn't even see the reINVITE...the switch probably tries tcp and that's not setup between the two. The invite above is sent to the a-leg over udp but I would expect and need it to be tcp in this case. The reINVITE is part of an existing dialog. We call loose_route() followed by some simple bflag setting and flag checking, t_on_reply(), ... then t_relay(). I do have a functional workaround but would prefer to avoid such manual handling by utilizing built-in functionality properly. # # relay the message # if(route(TEST_TOGW)) { if (!t_relay_to_udp()) { sl_reply_error(); } } else { if ($(hdr(Route)[-1]) =~ "tcp") { if(!t_relay_to_tcp()) { sl_reply_error(); } } else if (!t_relay()) { sl_reply_error(); } } I'm not 100% sure how reliable or fast this will be, but it does work so far in my simple tests. Is loose_route supposed to see and use the transport=tcp but isn't for some reason? It seems like the right thing to do to me. If not, is there anything else I can/should be doing in the tm and/or rr modules to make Kamailio realize it needs to send this message over TCP? If not in those two modules is there some recommended way perhaps via registrar or usrloc etc. to make Kamailio remember/store when a user is connected via TCP and be able to do a quick lookup before sending to them? Anything else I'm missing or not thinking of? Please let me know if I can further explain and rest assured any assistance will be much appreciated!!!

Keep-Alive in dialog "freeing a free fragment"
by Dirk Teurlings - SIGNET B.V. 16 Jun '15

16 Jun '15

Hi, (Kamailio 4.2.3) Working to get dialogs closed and cleaned up nicely I'm looking into the ka_interval and ka_timer parameter of the dialog module. The following is now happening. Scenario: 1. Call gets setup 2. Callee's internet connection drops 3. Call gets terminated (nicely) due to ka_timer/ka_interval 4. Log fills with "freeing a free fragment" after about 10 seconds Digging into this I saw that the dialog is being closed and cleaned properly in step 3. But it fails to remove/clean the timers used for the keep-alive. That's what triggers step 4, which in turn tries to clean the (or some of the) dialog space again. Is this expected behaviour when using the keep-alive options, or am I running into somekind of (known) bug? Thanks in advance for any help. -- Cheers, Dirk Teurlings

CANCEL request and subsequent 487 response to INVTE configuration problem
by Joao Alves 16 Jun '15

16 Jun '15

Hi, I'm creating a configuration is for a SIP <> HTTP gateway (performing protocol conversion) and thus all SIP messages and responses needs to be generated from the kamailio config file. I'm failing to create the case where the calling user abandons the session, and thus, following the reception of a CANCEL a 200 "OK" needs to be sent to this transaction and later the 487 "Request Terminated" to the SIP INVITE original session. On the traces I see: SIP INVITE (Cseq 1 INVITE) --> 100 Trying (Cseq 1 INVITE) <-- 180 Ringing (Cseq 1 INVITE) <-- SIP CANCEL (Cseq 1 CANCEL) --> 200 Ok (CSeq 1 CANCEL) <-- 487 Request Terminated (CSeq 1 CANCEL) Have then tried several options, trying to force the CSeq 1 INVITE but without success. t_reply_callid("$ci", "$cs", "487", " Request Terminated "); t_reply_callid("$ci", "$rm", "487", "Request Terminated"); t_reply_callid("$ci", "1", "487", "Request Terminated"); For instance, for the last I get the following log. 6(60226) exec: *** cfgtrace:request_route=[REQINIT] c=[/etc/kamailio/kamailio.cfg] l=705 a=28 n=t_reply_callid 6(60226) DEBUG: tm [t_lookup.c:1715]: t_lookup_callid(): created comparable call_id header field: >Call-ID: 76589ZTJmNTAwZDhlOTZiM2I3MjhhYzllNjgyOWVjZGZmMzk < 6(60226) DEBUG: tm [t_lookup.c:1719]: t_lookup_callid(): created comparable cseq header field: >CSeq: 1 INVITE< 6(60226) DEBUG: tm [t_lookup.c:1722]: t_lookup_callid(): just locked hash index 18668, looking for transactions there: 6(60226) DEBUG: tm [t_lookup.c:1749]: t_lookup_callid(): DEBUG: t_lookup_callid: transaction not found. 6(60226) DEBUG: tmx [tmx_mod.c:500]: t_reply_callid(): Lookup failed - no transaction Could you assist here?

Kamailio number of LCR rules
by Ali Taher 15 Jun '15

15 Jun '15

Hello, I'm testing LCR module in Kamailio and everything works as expected so far. Before going further , I just want to ask about how much rule in LCR_rule table and target in LCR_rule_target can Kamailio support . We are dealing with hundreds of millions of rules and targets. Kindly advise if Kamailio can support this number of rules. Thanks Ali

Removing parameters from user part of URI
by Alex Balashov 15 Jun '15

15 Jun '15

Hi, If I have an RURI like this: INVITE sip:4045551212;param=xyz@domain:port SIP/2.0 which transformations can I best string together in order to remove the ';param=xyz' bit and extract just the core user part value (4045551212)? {uri.user} returns '4045551212;param=xyz'. There are numerous transformations to help one access the parameters. What if I want to exclude the parameters? I've already scoured the available transformations, just hoping a second pair of eyes can tell me I've missed something useful.

ASYNC Module
by Aaron Hamstra 13 Jun '15

13 Jun '15

We just updated our development environment from 4.2.2 to 4.2.5 and started noticing the server sending a 500 I'm terribly sorry, server error occurred (1/TM) error back as soon as the async_route block gets called. I have removed everything from our async route other than an xlog statement trying to determine if something in that route block was causing the 500 to occur. It still happens even with only the xlog. If the async_route is not in the config, then the server does not send the 500 response. We rolled back to 4.2.2 and the problem no longer occurs. I have attached a sip trace of the messages. I believe the relevant parts of our config are below, please let me know if you need more from the config however. Any ideas? async_route("PUSHJOIN", "2"); -------------------------- route[PUSHJOIN] { xlog("L_INFO", "Does it get here?\n"); exit; } Thanks in Advance, Aaron

Hi all, I have an issue with mobile devices which get a different IP address each time they lose network. The scscf keeps the registration datas from the previous registrations, and forks requests toward all known identities. Is it possible to override the contact address at each register and keep only the last registration address per impi ? Thanks Regards JM

Problems with http_query(POST)

Hi, I'm finding a problem submitting a HTTP POST using the http_query(). Currently running on kamailio version: 4.1.8 on Debian wheezy. Normally this command has been worked fine, but since the body of the message increased (the POST data size is around 2000 bytes ) I start to get the following problem: 8(49381) ERROR: <core> [pvapi.c:1338]: pv_printf(): no more space for spec value 8(49381) ERROR: <core> [pvapi.c:1347]: pv_printf(): buffer overflow -- increase the buffer size... 8(49381) ERROR: <core> [sr_module.c:1696]: get_str_fparam(): Could not convert the PV-formated string to str 8(49381) ERROR: utils [functions.c:112]: http_query(): cannot get post value I've searched on how to increase buffer and found some global settings that could be directly, however the problem persist despite having set very high values for those: pv_buffer_size=32768 tcp_rd_buf_size=32768 maxbuffer=262144 Can someone assist and suggest a solution.

Mark CANCEL of one fork when another answers the call - old Kamailio
by Sebastian Damm 11 Jun '15

11 Jun '15

Hi, I'm looking for an option to mark CANCELs which are generated locally by Kamailio after receiving a 200 OK for another fork of the same call. In the tm module documentation I found the option local_cancel_reason which enables this. This option is available (and turned on by default) in newer Kamailios. But we have a legacy system still running 1.5 (and we don't want to upgrade it anymore, it will be obsolete pretty soon), which doesn't have this option yet. Is there a possibility to add a header to this locally generated CANCEL via some function in the config file, too? Thanks in advance. Best Regards, Sebastian

Kamailio LCR module memory concern
by Ali Taher 11 Jun '15

11 Jun '15

Hello, I'm using LCR module where I have 44 million rules and 13 million rule targets (not all rules have destinations). Noting that I'm running Ubuntu on virtual machine with 8GB allocated memory. When I'm setting lcr_rule_hash_size parameter to 268435456 (2 power 28) I got the following error : "no memory for rules hash table" in the log , noting that when I run ipcs -lm command I got max total shared memory shared memory (kbytes) : 8388608. When I'm setting lcr_rule_hash_size parameter to 1024,meaning 1024 rules will be fetched from the database (please correct if I'm wrong) Kamailio takes around 2 minutes and 30 seconds to start , which is worrying for me :( Please advise how many rules Kamailio can support (if 8 GB RAM are allocated to the server) , and what size every rule takes in the hash table built in the shared memory. Thanks, Ali

10 Jun '15

Hello, I am considering to release next major version of Kamailio (v4.3.0) next week, on Wednesday (June 10) or Thursday (June 11). The pool of things to fix is minor, Victor already updated deb packaging for 4.3, left to do: add docs for 4.3 series in wiki, prepare RPM packaging and build proper 'what is new' list of features. Testing didn't reveal new issues for me in the recent past as I run in two servers with live traffic. If you have issues with 4.3 branch, be sure you report them on Github tracker: - https://github.com/kamailio/kamailio/issues Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

Testing RPMs for v4.3.0
by Daniel-Constantin Mierla 09 Jun '15

09 Jun '15

Hello, in preparation for releasing v4.3.0 next week, I updated the specs for building RPMs from branch 4.3. However, I am not able to test the results, just made sure the build is ok. Packages are available at: - https://build.opensuse.org/package/show/home:kamailio:v4.3.x-rpms/kamailio43 I hope people here using RPMs will do some tests and provide feedback, interested mainly in: - it installs ok - after install, it starts ok with default configuration file - fifo and unix sockets are created now in /var/run/kamailio, so it has to be checked they are there - kamctl works ok for commands: ps, uptime and 'mi version' Some modules are not packaged in various versions, as I could not spot what are the packages needed for building them and if they are available with different names. For example, apparently jansson lib is on redhat, but not on centos, libev doesn't seem to be there. Also, I haven't had time to look at packaging erlang module. Help with the above is appreciated as well as helping building RPMs genrally. Maybe the init.d script needs to be reviewed and updated as well.

msilo storage of message id
by Shouvanik Chakrabarti 07 Jun '15

07 Jun '15

Hello. We have been using the msilo module to handle offline SIP messaging. I have noticed that the m_store function ends up storing all the records with the default message id which is zero. However m_dump uses this id to figure which messages have already been sent. Thus on calling m_dump on registration, no messages are dumped. We simply get a 'message already sent' debug log. Is there a way around this? Any help would be deeply appreciated. Thanks, Shouvanik.
