Having trouble associating response to message request
by Byran Carlock 31 Aug '18

31 Aug '18

Hello, I'll be the first to admit I'm a complete novice to Kamailio, but I'm learning due to necessity. I'm working on setting up Kamailio as a sip proxy (SBC?). The desired setup would be for Kamailio to as an external connection point to authenticate the connection and reverse proxy/NAT the rest of the traffic to the asterisk server, hiding internal topology as we go. Right now I'm using dispatcher with NAT and ALIAS to push connections to proxy@{PROXY IP} to proxy@{ASTERISK EXTERNAL IP}. I'm running into an issue where a "Message" is being sent, forwarded to the Asterisk server and responded to. Then Asterisk spawns a new call ID "To" the proxy rather than the original requestor which of course gets a 484 response. How can I somehow associate these two messages and complete the route?

How to detect and Hangup a call on network lost at Caller or Callee?
by Hamid Hashmi 31 Aug '18

31 Aug '18

Dear Users Please advise how to detect a network lost at caller or callee side. I have tried timeout_socket<https://kamailio.org/docs/modules/5.1.x/modules/rtpproxy.html#rtpproxy.p.ti…> and keepalives <https://kamailio.org/docs/modules/5.1.x/modules/dialog.html#dialog.p.ka_int…> method but nothing worked for me. RTPproxy did not send timeout notification to Kamailio (Issue #1597<https://github.com/kamailio/kamailio/issues/1597>) while there is no options packet within a dialog. Is there any other method to cater such scenario. Regards Hamid R. Hashmi

Quick way to enable/disable all uac outbound registrations
by Joel Serrano 31 Aug '18

31 Aug '18

Hi, On an active/passive kamailio cluster, we use keepalived to move a virtual IP between the nodes and all signaling goes to that VIP. One of our DID providers requires us to register with every single DID we have from them in order to receive calls for such DID (NOTE: we only want to have the "active" kamailio sending outbound registrations to the carrier). My idea was to have keepalived enable all the outbound registrations when the current node changes to MASTER and disable them when it changes to BACKUP. Is there a quick "enable all" or "disable all" for uac module outbound registrations or do I have to "know in advanced" all of them and enable/disable one by one? In the docs we have: *8.4. uac.reg_disable* *Disable a remote registration record based on a filter. The command has two parameter: attribute and value. The attribute can be: l_uuid, l_username, r_username or auth_username. The value is what should be matcheg against the value of the attribute in the remote registration record.* I don't know if there is an "all" or maybe if a wildcard would work, but from the description it doesn't seem to. Any ideas? Do you guys think this is taking a correct approach? All suggestions are more than welcome!! Thanks, Joel.

Request Line alases
by Wilkins, Steve 30 Aug '18

30 Aug '18

Hello All, If the below Requests from 40.40.40.40(Asterisk) is received by 10.10.10.10(Kamailio) Request Line: INFO sip:3145553313@10.10.10.10:5060;alias=30.30.30.30~43508~2 SIP/2.0 Shouldn't Kamailio forward this request to 30.30.30.30? so that the '200 OK' can sent back to Asterisk for the response. (In this scenario) Would it be ok to just force a '200 OK' back to Asterisk from Kamailio? Thank you,

Delay
by Daniel W. Graham 30 Aug '18

30 Aug '18

Recently encountered a delay issue, packets arrive on system but Kamailio doesn't process right away. Here are a few details, any direction on what I can do to narrow down is appreciated. The receive queue normally sits at 0 or has random spike, when this issue occurs receive queue remains high like the below output. Version 5.1.5 ss -4 -n -l | grep 5060 udp UNCONN 321536 0 207.241.130.2:5060 *:* tcp LISTEN 0 128 207.241.130.2:5060 *:* -dan

Interesting issue with ACK back from 200 OK INVITE
by Wilkins, Steve 30 Aug '18

30 Aug '18

Hello All, I have had an issue for quite some time where I needed to open two UDP ports (via LISTEN) for some softphone UAC's to stay connected. Funny enough there is one Provider that works with the Single UDP. I think I finally see why I was needing two listening UDP ports. When the ACK is returning from Asterisk to Kamailio, the ACK is coming back as protocol TCP, not SIP, causing the call to drop. I finally realized this but I am not sure what would cause this and why one provider phone works but not the others. Once this is resolved, I may actually say...It works! Thank you, -Steve

Using SEMS in IMS-ZTE Network
by Mojtaba 28 Aug '18

28 Aug '18

Hello, I am working with IMS (ZTE vendor), I want to use SBC in front of IMS network for some security policy (Hide Topology), I used SEMS as SBC in this regards, (like what we have in IMS/SEMS in kamailio by Mr Carsten Bock). When the Sebscriber want to register, The Register request received by sems and the forward to IMS(ZTE), But the "503 Service Unavailable" is received from IMS. I enable "enable_reg_caching=yes" in register.sbcprofile''s configuration file in sems. If i use kamailio, instead of SEMS, The Registration request is done successfully.In Kamailio i just forward the Register request to IMS.like this: route { if (is_method("REGISTER")) { $du = "sip:172.23.1.1:5080"; route(RELAY); } } Let me know do the issue is from myself or from IMS(ZTE)? In the fillowing, I paste all SIP Register signalling.

Listner problems
by Wilkins, Steve 25 Aug '18

25 Aug '18

Hi Joel, Actually, I have a strange issue. If I have a single UDP IP:Port listening, most Providers/Phones have two-way Audio/Video, however, with some Providers/Phones, I need to have two UDP IP:Port listners in order to get two-way Audio/Video. Here is the strange thing. If I enable two, the Providers/Phones that worked when I had a single listener only have one-way Audi/Video. I use Kamailio 5.1 and Asterisk 15.3 (pjsip). This behavior is so strange, Thank you, -Steve

Hi Florian, Thank you for your response. I checked and direct-media is off. Just as a recap, here is where I am I just can't get rtpengine to work.

Struggling with RTPProxy and RTPEngine
by Wilkins, Steve 24 Aug '18

24 Aug '18

Hello all, I can't seem to get either RTPProxy or RTPEngine to work correctly. I have decided to concentrate on RTPEngine because I have read that it works the best. I am using Asterisk with Kamailio in front. When I make calls, I see RTPEngine being hit but I continually get the error "Call-ID not found", calls work but media traffic doesn't go through RTPEngine. I have tried many combination of the flags but I seem to always get the same error. When I look at the tcpdump log, I see that the media offer is not on the RTPEngine port. Is there a common mis-configuration error that can cause this? I know I can send all my logs and configurations but I really want to try and resolve this as a learning experience. Thanks all, -Steve

Please check the attached where you can find my complete log file after starting Kamailio. Best regards Abdulaziz

Dispatcher - Force one end point active
by Marrold 23 Aug '18

23 Aug '18

Hi, We are currently using the dispatcher module and probing end points with OPTIONS, and making them active / inactive depending on the response: modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_reply_codes", "class=2;class=3;code=404") modparam("dispatcher", "ds_ping_from", "[REDACTED]") modparam("dispatcher", "ds_ping_interval", 20) modparam("dispatcher", "ds_probing_threshold", 1) modparam("dispatcher", "ds_probing_mode", 1) One of our suppliers endpoints doesn't respond to SIP OPTIONS, is it possible to force a single endpoint as active, but continue probing the rest? I've tried various settings - both globally and flags for the individual end point, but I couldn't seem to find the correct combination. Thanks Matthew

Re: [SR-Users] Struggling with RTPProxy and RTPEngine
by Wilkins, Steve 23 Aug '18

Good morning Daniel, If RTPEngine is on the same server as Kamailio (Asterisk being on another server), and RTP traffic is sent to and from RTPEngine, then the provider only needs to whitelist one IP-Address. I thought with RTPEngine that all RTP traffic would go through it and then it would pass it on to the correct destination. Is this correct? Thank you -----Original Message----- From: sr-users <sr-users-bounces(a)lists.kamailio.org> On Behalf Of Daniel Tryba Sent: Thursday, August 23, 2018 4:36 AM To: Kamailio (SER) - Users Mailing List <sr-users(a)lists.kamailio.org> Subject: Re: [SR-Users] Struggling with RTPProxy and RTPEngine MITRE WARNING: Do not open unexpected password-protected attachments. >>>Email originates from a non-MITRE system.

Am I missing something? In what sense do they need whitelisting? In a common NATed solution where is no white/blacklist needed. UA gets RTP endpoints from SDP, starts sending packets to ip/port and the destination will send back packets to the source ip/port, the router/firewall will just send this to the actual UA. I have yet to find an UA that cares about where the RTP stream is coming from with regards to the SIP traffic.

SIP and RTP Proxy for multiple Servers

Im very new to kamailio, we have some ptime issues which causes one way audio due to varies PBX vendors connecting to our class 5 softswitches I would like to use Kamailio as the SIP/RTP proxy in front of our class 5 soft switches I followed the example of freeswitch and kamailio. However the config is still hard for me below setup works, however RTP not being proxied, Looks like its its not, because im not using NAT, so RTP goes direct https://freeswitch.org/confluence/display/FREESWITCH/Kamailio+basic+setup+a… I would like to to ensure RTP proxy is always used(possible re-framing ptime) and we have multiple soft switches Is it possible to setup kamailio.cfg so my customers can point the endpoint to kamailio and domain names contains the server we want to use to register with? eg, softswitch 1 = 1.1.1.2 softswitch 2 = 1.1.1.3 softswitch 3 = 1.1.1.4 etc etc my current config #!KAMAILIO #!define IPADDRESS "1.1.1.1" #!define SWITCH_IPADDRESS "1.1.1.2" #!define FLAG_FROM_SWITCH 1 #!define FLAG_FROM_USER 2 # ------------------ module loading ---------------------------------- loadmodule "tm.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "sl.so" loadmodule "maxfwd.so" loadmodule "nathelper.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "path.so" loadmodule "rtpproxy.so" # ----------------- setting module-specific parameters --------------- modparam("nathelper|registrar", "received_avp", "$avp(s:rcv)") # ------------------------- request routing logic ------------------- #!ifdef WITH_NAT # ----- rtpproxy params ----- modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") # ----- nathelper params ----- modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org") # params needed for NAT traversal in other modules modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) #!endif # main routing logic route { # per request initial checks route(SANITY_CHECK); # CANCEL processing if (is_method("CANCEL")) { if (t_check_trans()) { t_relay(); } exit; } route(CHECK_SOURCE_IP); ################################## ### HANDLE SEQUENTIAL REQUESTS ### route(WITHINDLG); ############################### ### HANDLE INITIAL REQUESTS ### t_check_trans(); if (is_method("INVITE|REFER")) { record_route(); } if (is_method("REGISTER")) { add_path(); } if (isflagset(FLAG_FROM_SWITCH)) { # don't send INVITE from SWITCH back to SWITCH, set reply route to handle NAT and forward them along t_on_reply("EXTERNAL_REPLY"); } else { # set destination to your SWITCH $du = "sip:1.1.1.2:5060"; } route(RELAY); } route[SANITY_CHECK] { if (!sanity_check()) { #xlog("L_WARN", "$ci|end|message is insane"); exit; } if (!mf_process_maxfwd_header("10")) { #xlog("L_WARN", "$ci|end|too much hops, not enough barley"); send_reply("483", "Too Many Hops"); exit; } if ($ua == "friendly-scanner" || $ua == "sundayddr" || $ua =~ "sipcli" ) { #xlog("L_WARN", "$ci|end|dropping message with user-agent $ua"); exit; } if ($si == IPADDRESS) { #xlog("L_WARN", "$ci|end|dropping message"); exit; } } route[CHECK_SOURCE_IP] { if ($si == SWITCH_IPADDRESS) { setflag(FLAG_FROM_SWITCH); } else { setflag(FLAG_FROM_USER); } } # Handle requests within SIP dialogs route[WITHINDLG] { if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { route(RELAY); } else { if (is_method("NOTIFY")) { route(RELAY); } if (is_method("SUBSCRIBE") && uri == myself) { # in-dialog subscribe requests 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 #xlog("ACK without matching transaction ... ignore and discard"); exit; } } sl_send_reply("404","Not here"); } exit; } } onreply_route[EXTERNAL_REPLY] { route(NAT_TEST_AND_CORRECT); } route[NAT_TEST_AND_CORRECT] { if (nat_uac_test("3")) { if (is_method("REGISTER")) { fix_nated_register(); } else { fix_nated_contact(); } force_rport(); } if (has_body("application/sdp") && nat_uac_test("8")) { fix_nated_sdp("10"); } } route[RELAY] { #!ifdef WITH_NAT if (check_route_param("nat=yes")) { #setbflag(FLB_NATB); route(RTPPROXY); } if (isflagset(FLT_NATS) || isbflagset(FLB_NATB)) { route(RTPPROXY); } #!endif route(RTPPROXY); /* example how to enable some additional event routes */ if (is_method("INVITE")) { #t_on_branch("BRANCH_ONE"); t_on_reply("REPLY_ONE"); t_on_failure("FAIL_ONE"); } if (!t_relay()) { sl_reply_error(); } exit; # if (!t_relay()) { # sl_reply_error(); # } # exit; } # RTPProxy control route[RTPPROXY] { #!ifdef WITH_NAT if (is_method("BYE")) { #unforce_rtp_proxy(); force_rtp_proxy(); } else if (is_method("INVITE")){ force_rtp_proxy(); } if (!has_totag()) add_rr_param(";nat=yes"); #!endif return; }

RTPEngine wow's
by Wilkins, Steve 22 Aug '18

22 Aug '18

Hello all, I am still trying to get RTPEngine to work. At this point, when I make a call, I do see the offer in the rtpengine log, I also see the update of the SDP (c) changing it to 20.20.20.20. However, after that, there are no logs other than a bunch of "timer run time = 0.nnnnnnn sec", and the delete when I hang up the call. There is no RTP traffic what so ever in the rtpengine log (however, the call is completely successful, other than the RTP traffic not going through RTPEngine). Here is a breakdown of my configs (I borrowed this format from Maxim Fedorov because I thought it was very concise) Starting rtpengine => rtpengine --interface=internal/21.21.21.21--interface=external/21.21.21.21\!20.20.20.20 --listen-ng=127.0.0.1:12221 --dtls-passive -f -m 10000 -M 20000 -E -L 7 --log-facility=local1 RTPEngine Public IP: 20.20.20.20 RTPEngine Private IP: 21.21.21.21 kamailio.cfg modparam("rtpengine", "rtpengine_sock", "udp:127.0.0.1:12221") listen=tcp: 21.21.21.21:5060 advertise 20.20.20.20:5060 listen=udp: 21.21.21.21:5060 advertise 20.20.20.20:5060 rtpengine_manage call rtpengine_manage("trust-address replace-origin replace-session-connection external external media-address=20.20.20.20"); (I have placed this rtpengine_manage call at the beginning of all routes). I have tried many variations of rtpengine_manage parameters, and placement of the call itself, but I never see RTP traffic in the rtpengine log. Thank you to all who have looked at this, -Steve

invalid version 8 for table aliases found, expected 9
by Abdulaziz Alghosh 21 Aug '18

21 Aug '18

Hi everyone, i am trying to start kamailio 5.1.4 after the migration from Kamailio 3.0.3 but getting newly the following error: ERROR: <core> [db.c:450]: db_check_table_version(): invalid version 8 for table aliases found, expected 9 (check table structure and table "version") Allegedlly, this error is because of a wrong version of "aliases" table. I followed the Upgrade process starting from 3.0.3 till 5.1.x and I altered the structure of my aliase table accordinglly. The last new version of aliases is 8 as it is described at the upgrade from 4.2.x to 4.3.0 Even though, the error here says that the newest version is 9: May someone help me to find out if the aliases table's structure was renewed in between ?? Is there any modification in the data types? Thanks in advance Abdulaziz

ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed
by Abdulaziz Alghosh 21 Aug '18

21 Aug '18

Greetings, i am at the final stages of emigrating from kamailio 3.0.3 to 5.1.0 including our own module. Unluckily, after writing the command " kamctl start", the following error is popping up: * PID file /var/run/kamailio.pid does not exist -- Kamailio start failed* Thus, I used the command " kamailio -M 8 -E -e -dd " to get more debugging Info and the output is detailing the following: 0(10334) ERROR: db_mysql [km_my_con.c:129]: db_mysql_new_connection(): driver error: Can't connect to MySQL server on '192.168.1.207' (4) 0(10334) ERROR: <core> [db.c:318]: db_do_init2(): could not add connection to the pool 0(10334) ERROR: ABDUL_functions [ABDUL_chk.c:1069]: init_db(): failed to connect database URL=mysql://ABDUL:ABDUL@192.168.1.207/ABDUL 0(10334) ERROR: ABDUL_functions [ABDUL_functions_mod.c:296]: mod_init(): Module ABDUL_functions not correktly initialized, pid[10334] 0(10334) ERROR: <core> [core/sr_module.c:991]: init_mod(): Error while initializing module ABDUL_functions (//lib64/kamailio/modules/ABDUL_functions.so) Seemingly the error relates to old databases url ( "URL=mysql:// ABDUL:ABDUL@192.168.1.207/ABDUL" ) inside an old Kamailio.cfg file from my 3.0.3 package which I put under another different directory. This old Kamailio.cfg file #includes my own module, so he is exporting this url. Consequently, my module is trying to connect again to this databases. I do not know why both kamailio.cfg (new: /etc/kamailio/kamailio.cfg and old one out of /etc/kamailio) are both seen for kamctl or (/sbin/kamailio). I know that my new url inside the new /etc/kamailio/kamailio.cfg is read and connected but again not sure why my hidden old kamailio.cfg is still being read as well. the attached shows my init file for "SUSE Linux Enterprise Server 11 (x86_64)" and my used kamailio *default *file under /etc/default. Thanks in advance and best regards Abdulaziz

Call Transfer Scenario Using Freeswitch
by Sunil More 21 Aug '18

21 Aug '18

Hi All, I am using kamailio and freeswitch in my setup. While all users are registered on Kamailio, calls are routed to Freeswitch back to kamailio and then upstream providers. I can make user to user calls but in cases of transfer I am stuck. I am using a Polycom IP phone to test this scenario. While I initiate a attended transfer and click on transfer all the legs hangup. When I register all users on Freeswitch this works well. I am missing something on Kamailio side. Please point me in the right direction. Thanking You, Sunil More Ph : 9503338275

Enabling tcp_write_buf
by Gholamreza Sabery 21 Aug '18

21 Aug '18

Hi, In the documentation of "tcp_wq_max" option it is written that : > It has no effect if *tcp_write_buf *is not enabled. > > The interesting fact is that, there is not description of what it is and how one can enable it. There is even a question about it in the mailing lists: https://lists.kamailio.org//pipermail/sr-dev/2011-June/011521.html It seems that it is an inaccuracy in the documentation. If there is such an option how to enable it? Can anyone tell? Regards

Kamailio 5.1 Nathelper sipping on different transport protocols.
by Володимир Іванець 20 Aug '18

20 Aug '18

Hello everyone! I have system with Kamailio v5.1 which needs to send OPTIONS packets to all active clients. Here is full Nathelper module configuration: *modparam("nathelper", "received_avp", "$avp(s:received)")* *modparam("nathelper", "natping_interval", 30)* *modparam("nathelper", "ping_nated_only", 0)* *modparam("nathelper", "sipping_bflag", FLB_SIPPING)* *modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org <sip%3Apinger(a)kamailio.org>")* It works fine if client is connected over UDP. But as soon as I will switch to TCP or register with client that uses WS, Kamailio stops generating OPTIONS. Does anyone know if it is correct behavior or something is wrong? Thanks a lot!

JSONRPC-S and async RPC commands
by Juha Heinanen 20 Aug '18

20 Aug '18

JSONRPC-S module README has: 2. Limitations This module does not implement asynchronous RPC commands. It is unlikely that asynchronous RPC commands will be executed from an JSON-RPC over HTTP client. Does this mean that, for example, tm.t_uac_wait command cannot be executed using JSON-RPC over HTTP? If so, why "it is unlikely that asynchronous RPC commands will be executed from an JSON-RPC over HTTP client", since those commands are currently commonly executed from XMLRPC client using xmlrpc module? It would be nice if JSONRPC-S module could be used as replacement of xmlrpc module. -- Juha

domain-based routing
by David Villasmil 19 Aug '18

19 Aug '18

Hello all, I need to set up a multi-domain kamailio, i think in terms of accepting invites to different domains is pretty simple by using the "alias" parameter, that much i have clear. My doubt comes from the fact that I need to route outgoing calls also based on the domain. As of today, i have single-domain kamailios using dispatcher to load-balance and failover said calls. I think i should be able to use dispatcher here as well, separating the dispatcher list by GID, so that Domain1->gid:1 Domain2->gid: 2 Domain3->gid: 3 and so on... I don't have registrations on this server and none are expected. So i'm thinking i will received the invites like: sip:12345@domain1.com sip:12345@domain1.com sip:12345@domain1.com and so on... How would you guys go about associating the domain with the gid list in dispatcher? Thanks a lot for your help! Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

Is there a limit to the number of users which can be registered on Kamailio at any one time, or a configuration file which sets this. I have just installed Kamailio in a lab environment for testing purposes but I seem to only be able to register 1024 users, all remaining Register requests are ignored. I am not using a database to authenticate users or anything, just want to be able to register upto 10,000 users. regards Philip

how to enable tcp_write_buf?

Description of the var tells: Maximum bytes queued for write allowed per connection. Attempting to queue more bytes would result in an error and in the connection being closed (too slow). If tcp_write_buf is not enabled, it has no effect. What is tcp_write_buf and how to enable it? I could not find anything about it in core cookbook. -- Juha

kamailio rtp proxy set not working
by ANOOP V M 16 Aug '18

16 Aug '18

I have installed kamailio 5.1.4 version in ubuntu server. I need to route RTP packets through kamailio with SIP packets. I will explain the way i have set up everything. I have installed rtpproxy by apt-get install rtpproxy. i have edited "/etc/default/rtpproxy" file with the line 'EXTRA_OPTS="-F -s udp:127.0.0.1:7722 -l 34.201.122.249 -d DBUG:LOG_LOCAL0"' i have edited "/etc/init.d/rtpproxy" file as follows, DAEMON=/usr/bin/$NAME PIDFILE="/run/$NAME/$NAME.pid I have provided "#!define WITH_NAT" and "modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")" in my cfg file. started rtpproxy "service rtpproxy start" when i try "netstat -tulpn | grep rtp" it shows udp 0 0 127.0.0.1:7722 0.0.0.0:* 1437/rtpproxy So i think the rtpproxy is currently running fine. Now we can go to kamailio part. I have gone through the document " https://www.kamailio.org/docs/modules/5.0.x/modules/rtpproxy.html" to set up rtpproxy in the cfg file. checking the rtp ports "kamcmd rtpproxy.list" showing { setid: 0 url: udp:127.0.0.1:7722 index: 0 disabled: 0 weight: 1 recheck: 0 } I have enabled rtp proxy using "kamcmd rtpproxy.enable udp:127.0.0.1:7722 1". So i think ports are ready for rtp proxy. Now i will explain the call flow. I have enabled log using L_BUG. when i try a call from hangout number through my twilio trunk to my asterisk freepbx extension, set_rtp_proxy_set("1"); giving true value. But rtpproxy_offer(); giving -1 as result. syslog shows some errors like below, Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: DBUG:handle_command: received command "1934_4 Uc0,8,3,111,9,101 52001b5b71435b1c5392b39f2f6c975b@asterisk_ip:5060 asterisk_ip 14540 as4083c85f;1" Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: INFO:handle_command: new session 52001b5b71435b1c5392b39f2f6c975b@asterisk_ip:5060, tag as4083c85f;1 requested, type strong Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: ERR:create_twinlistener: can't bind to the IPv4 port 47926: Cannot assign requested address Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: ERR:handle_command: can't create listener Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: DBUG:doreply: sending reply "1934_4 E10#012" And also my header is not changed. As a result actuall rtp is going end to end between asterisk and twilio not through kamailio. Please help me with the details.

Very strange reinvite behaviour
by Alex Balashov 15 Aug '18

15 Aug '18

Hi, We have a scenario like this: ITSP -----> Kamailio -----> Endpoint (UDP) (TLS) So, TLS is only being used on the last hop, and the upstream interaction with the ITSP is plain-old UDP. Kamailio has the following listeners: listen=udp:1.1.1.1:5060 listen=udp:1.1.1.2:5060 listen=tcp:10.0.0.1:5060 listen=tls:1.1.1.1:5061 At some point, 'Endpoint' sends a reinvite which has the following RURI: INVITE sip:1.1.1.1:5061 SIP/2.0 This is clearly improper, and caused a loop that led to the rtpengine SDP loop issue I previously reported in another thread. So, in an effort to stop this, I added the following: if(has_totag()) { if(loose_route()) { ... if(is_method("INVITE")) { xlog("L_INFO", "[R-MAIN:$ci] Re-INVITE received from $si:$sp to RURI $ru\n"); xlog("L_INFO", "[R-MAIN:$ci] Reinvite body: $mb\n"); if(!is_method("ACK") && uri == myself) { sl_send_reply("400", "Bad Request"); exit; } } } But it doesn't work. It appears that the '400 Bad Request' rejection never happens, presumably because the this domain doesn't match 'myself'. Another perplexing mystery: the log message containing the reinvite's '$ru' does not show a RURI of 'sip:1.1.1.1:5061', but rather the remote target in the initial inbound INVITE, which we also logged: Contact: "Anonymous" <sip:Restricted@3.3.3.3:5060> The log message says: [R-MAIN:...] Re-INVITE received from 4.4.4.4:5060 to RURI sip:Restricted@3.3.3.3:5060;lr. Note a subtle detail here: the ';lr' parameter is present, which is an attribute of the Record-Route inserted by the sending ITSP (3.3.3.3). It's at the bottom of the Route set, of course, below Kamailio's two RRs (inserted for the ingress UDP interface and the egress TLS interface): Route: <sip:Restricted@3.3.3.3:5060;lr> This leads to two questions whose causes seem to be related: 1. Why does Kamailio think the request URI of this re-invite is something other than what $mb reveals it to be? 2. Is that, presumably, why it does not match 'myself'? 3. Why would Kamailio think it is actually set to the far-end Record-Route URI? This is version: kamailio 4.4.5 (x86_64/linux) d48094.

rtpproxy or rtpengine with Kamailio and Asterisk
by Wilkins, Steve 14 Aug '18

14 Aug '18

Good Morning everyone, Has anyone ever gotten rtpproxy/rtpengine to work with Kamailio and Asterisk? I have tried both, and even though I see no errors with either, and when I make calls I see rtpproxy/rtpengine traffic, I am still seeing media traffic go directly to and from Asterisk. I just can't get the media packets to not go directly from Asterisk to the Callee and visa-versa. Any ideas on where I am messing up in my kamalio.cfg file? Thank you!, -Steve

Hello, I migrated from Rtp_proxy module to Rtp_Engine. Everythings works fine apart the rewriting of the SDP description in Kamailio subst_body('/(^s=.*)/s=Test of a Sip call.\r/') Any ideas if this is supposed to be supported?

Can Kamailio interface with an asterisk server based on the fqdn of a call?
by Wilkins, Steve 14 Aug '18

14 Aug '18

Hi All, Is it possible for Kamailio to interface with a particular Asterisk Server based on the FQDN of a caller? I would like to pass calls received by Kamailio through to different Asterisk Servers based on the FQDN of the caller. I have used Load Balancing before, but I want to select which Asterisk Server the call is directed to. Thank you,

Rtpengine?
by Wilkins, Steve 14 Aug '18

14 Aug '18

HI All, I am not sure if I understand it correctly but I thought that I could use rtpengine to redirect media packets. My current SIP flow is => Softphone=>Kamailio=>Asterisk=>Kamailio=>Softphone, and Media flows from is Asterisk<=>softphone. But I don't want Media to flow this way. That is, I do not want Asterisk and the Softphone to be aware of each other. I would like the Media to go through Kamailio just like SIP packets do. I installed rtpengine and it starts and runs with no errors. I even see traffic with the call is made but media traffic still flows from softphone<=>asterisk. Any ideas? Thank you,

Re: [SR-Users] problem with compiling kamailio version 5.1.4 including a private Module
by Abdulaziz Alghosh 13 Aug '18

13 Aug '18

Hi Henning, thanks again. I found meanwhile the root cause. It caused as you said by the old logic of the make file. I used instead the new Formula of the tm module’s make file (as i remember). Consequently, it did not bring the compilation through those unwanted libraries. I will spot the details later when i am back in office next Monday. BR Abdulaziz On Thu 9.

app_lua and lua_run parameter count
by Asgaroth 13 Aug '18

13 Aug '18

Hi All, Quick question with regards the lua_run function in app_lua module. The documentation for v5.0.x states: "Execute the Lua function 'func' giving params as parameters. There can be up to 3 string parameters. The function must exist in the script loaded at startup via parameter 'load'. Parameters can be strings with pseudo-variables that are evaluated at runtime." Does this mean that lua_run can only have 3 parameters, or, does it mean that the function within the lua script can have up to 3 parameters? I have a function within lua that currently needs 3 parameters, so I'm hoping I can do the following: lua_run("some_function", "param_1", "param_2", "param_3") However, I'm not sure, from the documentation, if I can do this. On a side note, but related, can I pass defined variables/constants as parameters to lua_run too, for example, something like: #!define VAR_1 1234 #!define VAR_2 hello lua_run("some_function", "$rd", VAR_1, VAR_2) Some clarification would be greatly appreciated. Thanks for reading.

Lua KEMI crash
by Ivaylo Markov 13 Aug '18

13 Aug '18

Hello, I have Kamailio 5.1.4 (from deb.kamailio.org) running on a Debian 9 AMD64 VM with 1 CPU and 1G of RAM on ESXi. For KEMI I am using the liblua5.1-0:amd64 package, version 5.1.5-8.1+b2. The configuration is rather simple - dispatcher module reading the gateways from a file and forwarding everything to them based on a custom variable. There are 2 gateways in the file being pinged with OPTIONS packets every 10 seconds. Only a single SIP user is connecting to the machine (besides the occasional scanner). I can post the config if necessary, but I don't think that is the issue (see below). The crash has happened twice already - once on 2018-08-07 19:45 and 2018-08-08 14:33 EEST. You can find an excerpt from the Kamailio debug log at https://paste.fedoraproject.org/paste/bvyUMj3s5g2CcBN3JSBt5A/raw. As you can see, it crashes when trying to run the Lua route on an incoming packet. I am assuming the problem is this: Aug 8 14:33:14 lb-dev1 kamailio[13209]: *** Error in `/usr/sbin/kamailio': realloc(): invalid next size: 0x00005573dbff1ef0 *** However, I could not find any (direct) `realloc()` calls in the source for app_lua, so maybe this is an issue somehwere in liblua... Thoughts? Ivaylo

USRLOC db_mode=4 and server_id
by Darren Williams 13 Aug '18

13 Aug '18

I am currently using multiple instances of Kamailio with a common database and using the usrloc module with db_mode=4 and server_id to filter the contacts that get loaded at startup on each server. The problem I seem to have is that using the RPC call ul.add there I cannot see any parameter to send to specify the server_id. The server_id that the contact is given is 0. If I manually go into the db and modify the server_id everything works as expected. I think I must be missing something somehwere as I'mn sure you shouldn't need to do this. Can anyone help please. Thanks Daz

MYSQL and various
by Laura 12 Aug '18

12 Aug '18

Dear list, on my kamailio 4.4.7 i use interactions with MYSQL. For example .. i use it for some black list control and other like this.. sql_query("cb", "select id from blacklist where cli='$var(g2)' and (ippeer = '$si' or ippeer = 'ALL')", "rabl"); if($dbr(rabl=>rows)>0){ sql_result_free("rabl"); sl_send_reply("403","Forbidden blacklist"); exit; } sql_result_free("rabl"); I was wonder what was the best method to prevent the query going on if mysql don't respond for high load or other situation.. If Mysql is not able to reply to the query tight now the call continue over the configuration... what is the best way to prevent this and for examples drop it with a standard SIP 503 error. I have search on docs.. but i haven't found any valid way. Thanks Laura

UDP workers block when one or more rtpengine instances go offline
by Sebastian Damm 10 Aug '18

10 Aug '18

Hi, we run multiple rtpengine servers to share the load. Whenever we need to take an rtpengine server offline, we used to just block the control port via iptables, then no new calls ended up on this instance of rtpengine. This worked pretty well in Kamailio 4.4.5. However, since Kamailio 5.0, and the problem persists with 5.1.4, Kamailio hangs almost immediately after we block the control port traffic. In the log file there are almost no packets processed except every few seconds, which looks like a timeout thing. Did we configure anything wrong there? Or is the "dead rtpengine detection" just broken? Our configuration: loadmodule "rtpengine.so" modparam("rtpengine", "rtpengine_disable_tout", 120) modparam("rtpengine", "setid_avp", "$avp(rtpsetid)") modparam("rtpengine", "rtpengine_sock", "0 == udp:1.2.3.4:9001=2 udp:1.2.3.5:9001=2 udp:1.2.3.6:9001=2") modparam("rtpengine", "rtpengine_sock", "1 == udp:2.3.4.5:9001=2") Any help appreciated.

Example: # kamcmd htable.dump propertiesHash { entry: 1 size: 1 slot: { item: { name: cfg.env But the htable.reload command fails: error: 500 - Failed to open htable db connection The Kamailio log reports that it can't connect the db : DEBUG: ctl [../../core/io_wait.h:380]: io_watch_add(): DBG: io_watch_add(0x7f68c74ab300, 10, 3, 0xdc9410), fd_no=1 DEBUG: ctl [io_listener.c:442]: handle_new_connect(): handle_stream read: new connection (1) on /var/run/kamailio//kamailio_ctl DEBUG: <core> [core/sr_module.c:694]: find_mod_export_record(): find_export_record: found <db_bind_api> in module db_mysql [/usr/lib64/kamailio/modules/db_mysql.so] DEBUG: <core> [db.c:209]: db_bind_mod(): using db bind api for db_mysql DEBUG: <core> [db.c:314]: db_do_init2(): connection 0x7f68cc354c10 not found in pool DEBUG: db_mysql [km_my_con.c:98]: db_mysql_new_connection(): opening connection: mysql://xxxx:xxxx@/siprouter ERROR: db_mysql [km_my_con.c:124]: db_mysql_new_connection(): driver error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2 "No such file or directory") ERROR: <core> [db.c:318]: db_do_init2(): could not add connection to the pool ERROR: htable [ht_db.c:92]: ht_db_open_con(): failed to connect to the database My local db is located at /myqdata/mysiprdb/data where is the mysiprdb.sock file. But the log shows that Kamailio is looking for /var/lib/mysql/mysql.sock. Does this error make sense to you ? Is it possible to fix this problem by configuration in Kamailio ? My kamailio.cfg script contains : # ----- htable modparam("htable", "db_url", "mysql://[kamailio]/siprouter") modparam("htable", "fetch_rows", 1000) modparam("htable", "htable", "mbxrangeHash=>size=4;dbtable=mbxrange;") modparam("htable", "htable", "abpqHash=>size=12;dbtable=abpq;") modparam("htable", "htable", "zabpqHash=>size=12;dbtable=zabpq;") modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;") In the /myqdata/mysiprdb/data/my.cnf, I added the following entries for Kamailio: [kamailio] socket = /myqdata/mysiprdb/data/mysiprdb.sock user = siprouter password = ########## default-character-set = utf8 Thanks all for help.

Re: [SR-Users] problem with compiling kamailio version 5.1.4 including a private Module
by Abdulaziz Alghosh 09 Aug '18

Hello Henning, thanks a lot for your response and explanation. strutils.[c,h] and strcommon.[c,h] are almost the same. So I modified my included header from stcommon[] to strutils as you mentioned. Unfortunately, I surfed sequentially Kamailio version upgrades. Even though, i did not found such hints about this modification. So I have some doubts the called headers and codes from our own module. Hence, I am asking for yor advice. What I am trying to do now is compiliing our module separately under it is own directory so I gain the Shared Object file (.so). Somehow our Module is requring cds, presence and xcap libraries. But the strange thing is that headers from these libraries are #including other headers assuming these included header files are under the same library's directory (but in fact most of the header files are under ../src/core/). For example : Making in cds CC (gcc) [L libser_cds.so.0.1] cds.o In file included from cds.c:2: /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/memory.h:125:21: warning: mem/mem.h: No such file or directory /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/memory.h:126:25: warning: mem/shm_mem.h: No such file or directory In file included from cds.c:3: /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/sync.h:30:22: warning: locking.h: No such file or directory In file included from cds.c:4: /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/logger.h:42:20: error: dprint.h: No such file or directory make[2]: *** [cds.o] Error 1 make[1]: [cds] Error 2 (ignored) Those libraries are delivered with version 5.1.4 itself so i do not think it is a good idea to modify the paths of the included header files to compile my module. because most probably these libraries are needed by standard default modules of kamailio. I hope this is not too much for you to inspect. Note: The attached has the log files ( resulting from make all and install ) .

problem with compiling kamailio version 5.1.4 including a private Module
by Abdulaziz Alghosh 09 Aug '18

09 Aug '18

Greetings, i am somehow newbie with Kamailio and trying to migrate from kamailio version 3.0.3 to 5.1.4. Former fellows had developed own modules which needed "strcommon.h" and "strcommon.c". These last two files are not delievered with version 5.1.4. but I copied them under ../src/core/ thinking it would be beneficial. Unfortunately, after make prefix / (and including our own module) all, it seem that several dependencies exist. Especially from header files under ..src/lib/xcap/ and ../src/lib/presence Can somebody tell me how "strcommon.h" and "strcommon.c" where replaced in version 5.1.4 ? Best regards Abdul Aziz

Questions about changes between 5.0.1 and 5.0.7
by Ginhoux, Patrick 08 Aug '18

08 Aug '18

Hi, Following a problem with the kamcmd htable.reload with Kamailio 5.0.1 (see related thread for this), I have upgraded to the 5.0.7 level (with some difficulties due to my specific environment). My server runs the RHEL 7.4 distribution. Now the upgrade is complete, I notice that that are changes not really documented: - The kamailio-perl-5.0.7-1.el7.x86_64.rpm requires to install the mod_perl module that doesn't exist anymore in RHEL 7. It needs to be installed from the EPEL repository - The init script for kamailio has been changed from the old method to the fully compliant method for system unit for RHEL 7 for example: With the 5.0.1 level we have the "/etc/rc.d/init.d/kamailio" With the 5.0.7 level we have now the "/usr/lib/systemd/system/kamailio.service" So my questions/comments are : - Why the mod_perl module is required between 5.0.1 and 5.0.7 (question posted in the attached message) ? - In the previous kamailo init script, I added a condition to start MySQL before kamailio by adding this entry in the script : # Required-Start: $syslog $network $mysqld The new script contains the After command : [Unit] Description=Kamailio (OpenSER) - the Open Source SIP Server After=network.target Should I change the After line with this : After=network.target mysql.target to have the same condition? In all the cases, some documentation must be changed to provide more details. Thanks in advance for the answers. Cordialement. Patrick GINHOUX

RTPEngine UDP receive queue issue

Hi, We have an RTPEngine that occasionally finds itself in this state of CPU usage: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 25476 root 20 0 2929600 80820 1900 S 156.2 0.1 259:05.54 rtpengine The journal is a dizzying stream of: Aug 06 20:58:47 gw1 rtpengine[25476]: ERR: [1074537188_44545952 port 61666]: Too many packets in UDP receive queue (more than 50), aborting loop. Dropped packets possible It eventually leads to increasing CPU usage and a degeneration of audio quality until RTPEngine is restarted. It would be appreciated if someone could shed some light on the nature of this queue and what we can do about this problem. Is this referring to a netfilter packet forwarding queue, or is it a receive queue of the RTPengine user space control process? Can its size be increased or tweaked with kernel parameters?

I am using Kamailio (5.0.1) and MSILO module for offline messages but I have a problem with users behind NAT. According to module overview, MSILO is forwarding the offline messages to contact address provided in REGISTER request. Is there any way to overcome this and send the messages to the external client IP? Thanks, Michalis Michael

Hi, currenty (the last few days) there has been a spam attack on freenode, #Kamailio is currently full of spam messages, I was wondering if who has operator rights could set the channel to +r (only registered users can send messages) as suggested by freeenode admins The channel usually has only few messages and with all this spam it becomes impossible at all to use it. Greetings, Enrico.

Kamctl Stats Update
by Noah Mehl 07 Aug '18

07 Aug '18

Hey all, I was wondering if the kamctl stats output could be updated to provide a bit more parseable JSON? For instance: # kamctl stats shmem | jq . { "jsonrpc": "2.0", "result": [ "shmem:fragments = 18", "shmem:free_size = 467187808", "shmem:max_used_size = 69694104", "shmem:real_used_size = 69683104", "shmem:total_size = 536870912", "shmem:used_size = 41048984" ], "id": 4300 } I would hope would be more like this: { "jsonrpc":"2.0", "result":[ { "shmem":[ { "fragments":18, "free_size":467187808, "max_used_size":69694104, "real_used_size":69683104, "total_size":536870912, "used_size":41048984 } ] } ], "id":4300 } I apologize in advanced because I don’t have the skillset to contribute such a feature.

DMQ problems
by Aleksandar Sosic 05 Aug '18

05 Aug '18

Hi, I've set up a dmq server for other kamailio nodes with this parameters: ``` modparam("dmq", "server_address","sip:10.0.0.101:5060") modparam("dmq", "notification_address", "sip:127.0.0.1:5060") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) modparam("dmq", "ping_interval", 15) ``` On the kamailio nodes the config is the following: ``` modparam("dmq", "server_address", "sip:10.0.0.x:5060") modparam("dmq", "notification_address", "sip:10.0.0.101:5060") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) modparam("dmq", "ping_interval", 15) ``` On the kamailio dmq server I've got this in the logs: ``` 25(41) ERROR: dmq [notification_peer.c:596]: notification_resp_callback_f(): deleting server sip:127.0.0.1:5060 because of failed request 25(41) ERROR: dmq [notification_peer.c:599]: notification_resp_callback_f(): not deleting notification_peer ``` On the kamailio nodes the same thing with the ip of the dmq server: ``` 25(112) ERROR: dmq [notification_peer.c:596]: notification_resp_callback_f(): deleting server sip:10.0.0.101:5060 because of failed request 25(112) ERROR: dmq [notification_peer.c:599]: notification_resp_callback_f(): not deleting notification_peer ``` The request route on the dmq server is simple as this: ``` request_route { if(is_method("KDMQ")){ dmq_handle_message(); } }#end request_route ``` I've tried with some xlog-s inside the if(is_method("KDMQ")) but they don't show up so the dmq_handle_message() is not even executed. I've also tried to bind the dmq server to a different port but with no success on making it work. The dmq.list_nodes shows only the dmq server IP and the current node IP, the IPs of other nodes are not shown: ``` root@proxy-94b6ccf46-t8fx2:/# kamcmd dmq.list_nodes { host: 10.0.0.101 port: 5060 resolved_ip: 10.0.0.101 status: active last_notification: 0 local: 0 } { host: 10.0.0.45 port: 5060 resolved_ip: 10.0.0.45 status: active last_notification: 0 local: 1 } ``` And it's the same on all other kamailio nodes: dmq server ip and local ip.

Security announcement related to Kamailio
by Henning Westerholt 04 Aug '18

04 Aug '18

Hello, I want to highlight that the last stable versions (for the two maintained series: 5.0 and 5.1) include fixes for an security issues that can crash a running instance of Kamailio, therefore it is strongly recommended to upgrade. Details: There exists a security vulnerability in the Kamailio SIP server related to "To" header processing. A specially crafted SIP message with double "To" header and an empty "To" tag causes a segmentation fault and crashes Kamailio. The reason is missing input validation in the "build_res_buf_from_sip_req" core function. If an attacker sends many of this messages this would lead to a Denial of Service of the attacked infrastructure. This is especially critical as no authentication for the remote source is needed. You find all the details including a proof of concept code in the published security announcement in my blog: https://skalatan.de/blog/advisory-hw-2018-05 A CVE report for this issue is going to be created as well in the near future. The issues were found some months ago and were fixed quickly. The code related to the reported issues is rather old and there are no known incidents of exploiting these issues so far. However, once the CVE report becomes public, there could be a higher risk of exploitation. Please address any detailed technical questions related to this to the developer list at sr-dev(a)lists.kamailio.org . In case of confidential remarks related to this or other security issues, please address them to the Kamailio Management. Best regards, Henning Westerholt -- Henning Westerholt https://skalatan.de/blog/

Final reply code is wrong in case of 302 and 486 busy
by Marco Capetta 03 Aug '18

03 Aug '18

Hello, we have a problem of final reply code in case of 302 and then 486 busy. This is our scenario: A, B and C are subscribers. A ----------> Kamailio ----------> B Kamailio <---302---- B Kamailio -----------------------> C Kamailio <---486----------------- C A <---302---- Kamailio Expected behavior: Kamailio should reply to A with 486, as C was busy, and not 302. We have kamailio v5.1.4 In the call to B we set both failure and branch_failure: t_on_failure("failure_route"); t_on_branch_failure("failure_redirect"); in order to handle the 302 redirect per branch with: event_route[tm:branch-failure:failure_redirect] { if($T_reply_code == 301 || $T_reply_code == 302) { do redirect ... } } and the final failure with: failure_route[FAILURE_ROUTE_LOCAL] { do something ... } Since we have 'modparam("tm", "failure_reply_mode", 3)' my expectation is to get the winning reply from the branch of last step. Is there any configuration I'm missing? Since we manage the redirect with a branch-failure, is the winning reply calculated in a different way? Thanks Marco

is_method not matching message type KDMQ breaking DMQ bus. (master branch)
by Asgaroth 02 Aug '18

02 Aug '18

Hi All, I've come across and oddity whereby my is_method("KDMQ") checks are not matching. I'm testing with kamailio master: version: kamailio 5.2.0-dev6 (x86_64/linux) a16272 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144 MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: a16272 compiled on 15:27:21 Jul 31 2018 with gcc 7.3.1 Sample routing logic: request_route { route("InitialMessageChecks"); exit; } route[InitialMessageChecks] { xlog("L_INFO", "Received message type $rm from $si:$sp on $Ri:$Rp"); if ( is_method("KDMQ") ) { xlog("L_INFO", "KDMQ check passed."); } if ( is_method("OPTIONS") ) { xlog("L_INFO", "OPTIONS check passed."); } if ( is_method("SUBSCRIBE") ) { xlog("L_INFO", "SUBSCRIBE check passed."); } } In the logs I am only receiving the 1st log line in the initial message checks route for message types of KDMQ, eg: INFO: <script>: Received message KDMQ from 1.1.1.1:5060 on 1.1.1.2:5060 INFO: <script>: Received message KDMQ from 1.1.1.3:5060 on 1.1.1.2:5060 I never seem to hit the is_method check log line when the method type is KDMQ. I do see the options/subscribe logs though: INFO: <script>: OPTIONS check passed. INFO: <script>: SUBSCRIBE check passed. nothing for KDMQ. Reason for asking is: this check never matches and breaks the dmq bus: if ( is_method("KDMQ") ) { if ( dmq_is_from_node() ) { dmq_handle_message(); exit; } else { exit; } } Any thoughts, or am I going crazy :) Thanks

Greetings, I thought about that but i wasn't sure it would be safe. But, in this case, the Request-URI domain will be the only place where Kamailio will look to find out the destination right within the dialog right? I'm going the statelless way, so that might be the correct answer. Thanks for your help

get_out_socket(): no socket found
by Ilie Soltanici 02 Aug '18

02 Aug '18

Daniel, Not, those IP are in a different subnet. There is a firewall - running on a different device. Ping and SIP Messages are going very well from 2.2.2.2 to 8.8.8.8. I was able to solve this issue by disabling mhomed and set "listen" external interface with IP address 2.2.2.2 on top in the configuration file. Now, Kamailio is starting without any errors and is registering to the upstream provider, but I just I am wondering if it's possible to specify an outgoing socket for uac module in the configuration file? Thank you.

Greetings, I have a Kamailio server set up without Registers. I'm using Dispatcher module for balancing and selecting the destinations. I need to do some changes in the message according to the chosen destination. If it's the first INVITE, after Dispatcher operations, i can do it using $dd or $du variables. However, in later messages, like a BYE, i can't seem to access the method's destination IP. Is there any variable that i'm missing? I've tried $route_uri but it only returns the kamailio's own IP, since it's the only IP in the "Route" header. Thanks in advance, Cheers

Hi All, I'm unable to register an extension to the Upstream Provider by using uac module. Getting the following error: *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: <core> [core/forward.c:181]: get_out_socket(): no socket found* *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: <core> [core/forward.c:183]: get_out_socket(): no corresponding socket found for(udp:8.8.8.8:5060 <http://8.8.8.8:5060>)* *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: tm [ut.h:317]: uri2dst2(): no corresponding socket found for "svr04.nuacom.net <http://svr04.nuacom.net>" af 2 (udp:8.8.8.8:5060 <http://8.8.8.8:5060>)* *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: tm [uac.c:449]: t_uac_prepare(): no socket found* *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: uac [uac_reg.c:1161]: uac_reg_update(): failed to send request for [1050]* Kamailio is listening on 2 interfaces: [root@kamailio user]# /usr/local/sbin/kamcmd core.sockets_list { socket: { proto: udp address: 10.1.1.11 ipaddress: 10.1.1.11 port: 5060 mcast: no mhomed: no } socket: { proto: udp address: 2.2.2.2 ipaddress: 2.2.2.2 port: 5060 mcast: no mhomed: no } mhomed is enabled in the configuration file: *mhomed=1* I'm not using ' force_send_socket' anywhere in the configuration file.

Thank You.

RTP Proxy
by Alex Tatham 31 Jul '18

31 Jul '18

Hello everyone, I'm in the process of moving approx. 100 Kamailio/Media Proxy (AG Projects) servers to Kamailio/RTPEngine. I have all the functionality in place and I have a handful of servers in production. I'm trying to monitor the RTP engine (using Munin) and I'm graphing the values returned from the RPC command rtpengine.get_hash_total. This value is slowly increasing over time and I'm trying to find out if this is something I should worry about. I want to make sure that sessions are not being left open and therefore the software will eventually run out of ports. To give some values, if I make 100 calls the call will be around 25 after those calls. >From all other tests I have done including a check through the verbose logs I can see the sessions are being closed at the end of the calls. Can anyone help with this at all or does anyone possibly have any better ideas?

Is anyone having issues with dialog metrics when DMQ is enabled?
by Joel Serrano 30 Jul '18

30 Jul '18

Hi guys, Is anyone having issues gathering active/early dialog metrics from kamailio when DMQ is enabled? I have an open ticket in GH ( https://github.com/kamailio/kamailio/issues/1591) and I'm wondering if this could be happening to anyone else? So far the theory is that the counter goes below 0 and that creates the problem. I'd love to hear from you if you are experiencing this too. If any of you are using Kamailio 5.1 + DMQ and gather active/early dialog metrics using the stats.fetch or stats.get_statistics rpc commands, do you ever get values close to 64BIT ULONG_MAX? (18446744073709551615)?? Thanks! Joel.

Kamailio 5.0.X RPM packages/repo broken
by Patrick Wakano 27 Jul '18

27 Jul '18

Hello list, Hope you all doing fine! I've been trying to install Kamailio packages from the opensuse repo (as per https://www.kamailio.org/wiki/packages/rpms) but the installation is failing with this message: Downloading packages: Delta RPMs disabled because /usr/bin/applydeltarpm not installed. kamailio-ims-5.0.7-1.el7.cento FAILED http://download.opensuse.org/repositories/home%3A/kamailio%3A/v5.0.x-rpms/C…: [Errno 14] HTTP Error 416 - Requested Range Not Satisfiable --:--:-- ETA Trying other mirror. kamailio-5.0.7-1.el7.centos.x8 FAILED 77% [============================================================- ] 1.0 MB/s | 4.9 MB 00:00:01 ETA http://download.opensuse.org/repositories/home%3A/kamailio%3A/v5.0.x-rpms/C…: [Errno -1] Package does not match intended download. Suggestion: run yum --enablerepo=home_kamailio_v5.0.x-rpms clean metadata Trying other mirror. I've successfully installed the 5.0.7 version on Friday (06/07) but I've noticed the packages have changed last Saturday (07/07/2018).... Given this error message looks like the repository is broken somehow.... Is anyone aware of such issue? I haven't tried the 5.1.X repo because my script was not migrated to 5.1.X yet.... Thanks, Kind regards, Patrick Wakano

No cdr after Kamailio 5.0.4 and 5.2 dev restart
by Kordován Szabolcs 27 Jul '18

27 Jul '18

Hi All, In March there was a discus about this issue. We tested the new 5.2 dev and 5.0.4 version of Kamailio and we experience that If we restart Kamailio during the call the cdr won't be stored in table acc_cdrs but the data will be inserted to table acc and data will be deleted from table dialog and dialog_vars. Did I omit the fix for it? Thanks for your help. Best regards, Szabolcs
