SIP_DOMAIN in /etc/kamailio/kamctlrc
by Trent 17 Aug '17

17 Aug '17

Hello. I have not been able to find anything in the wiki, or documentation which covers this. The only item I have found is related to a module. >From the information, I have gleaned on this, it is clear an IP address, or a domain name is to be set here. What is not clear, is if the server is on multiple IP address whether they are on a WAN, LAN, or both, if multiple IP addresses are need, or can be added. I have a situation where I have a public WAN address, and a LAN address. Thanks a bunch!

sipcapture/HEP msg sizes>1500
by Daniel Tryba 16 Aug '17

16 Aug '17

While looking into HOMER I saw that large INVITEs got truncated in the webinterface, looking at the HEP traffic these (UDP) messages got fragmented in transport (asterisk/res_hep) and I started to think these were not getting reassembled correctly. Only to find out the database schemas have set the msg size set to varchar(1500). Is there any good reason for not changing this to a bigger default?

RTP loops
by Mauro Costantini 16 Aug '17

16 Aug '17

Hi everyone, we have an installation with: - 1 kamailio instance - with 2 interface, one with public and one with private IP (for local communication to the db and asterisk ). We use keepalived service for failover and so, every interface has 2 IPs: the real one and the “virtual” one for the keepalived service - some asterisk instances for transcoding and billing - with one interface with private IP - 2 RTP (rtpengine) instances - with 2 interfaces, one with public and one with private IP A few times happens a loop on the RTPengine and we could see a lot of lines like this in the log: “Too many packets in UDP receive queue (more than 50), aborting loop. Dropped packets possible” This loop doesn't stop until all the resources are exhausted and it results in the freeze of the machine. We don’t understand the reason why these loops are generated. We have 2 cases: 1) we send an INVITE to the CPE (a Bria on iOS) The CPE answers with a "100 Trying", a "180 Ringing" and a few seconds later sends us 3 packets of "200 ok" with SDP like this: SIP/2.0 200 OK Via: SIP/2.0/UDP 178.250.x.y;branch=z9hG4bKb842.29952898c30d6d06b75b916618357ccd.2 Via: SIP/2.0/UDP 192.168.x.y:5090;rport=5090;branch=z9hG4bK7fd100fb Record-Route: <sip:178.250.x.y;r2=on;lr=on;ftag=as26b82ac7;did=cb5.0ce;nat=yes> Record-Route: <sip:192.168.x.z;r2=on;lr=on;ftag=as26b82ac7;did=cb5.0ce;nat=yes> Contact: <sip:6051018****@158.148.x.y:3180;rinstance=ffdff5e0142dfd2d> To: <sip:6051018****@192.168.x.z>;tag=29859d3c From: <sip:051438****@192.168.x.y>;tag=as26b82ac7 Call-ID: 698200851849894c5874186163abe668@192.168.x.y:5090 CSeq: 102 INVITE Allow: INVITE, ACK, CANCEL, BYE, REFER, INFO, NOTIFY, OPTIONS, UPDATE, PRACK, MESSAGE, SUBSCRIBE Content-Type: application/sdp Supported: replaces User-Agent: Bria iOS release 3.9.7 stamp 38887.38893 Content-Length: 230 v=0 o=- 1085831961 3 IN IP4 100.81.231.195 s=Cpc session c=IN IP4 100.81.231.195 t=0 0 m=audio 65454 RTP/AVP 18 101 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=sendrecv Could the IP of the media part (100.81.231.195 in the CGNAT 100.64.0.0/10) be the cause of the loop?

Can somebody help us in order to prevent this loop? In the attached images you can see: [0] a call, our machines IPs, an ACK from public interface of our SBC to its private one; and than a lot of ACKs from the keepalived IP to the private IP of our SBC. [1] one of these strange ACKs, they are all different in content, but similar in structure: multiple Record-Route / Via, truncating too long message; [2] a "never ending" BYEs. After modifying the configuration adding some "listen=IP_ADDR:PORT" (and of course excluding the keepalive IP) we had no loops but is this enough? Why Kamailio generated the loops? Is there something else we should review in our config? Any advice would help a lot. Thanks. [0] https://goo.gl/rWh5db [1] https://goo.gl/MNShq9 [2] https://goo.gl/6mxepG

UAC reg_random_delay issue
by Ivo Vastert 16 Aug '17

16 Aug '17

Hi, I'm using the UAC module in Kamailio to setup about 500 outbound registration towards a single host. The issue I'm currently experiencing is that when we start Kamailio all this 500 registrations are initiated at once towards the host which can't handle all the requests at the same time. Therefor I tried to spread the registrations using the reg_random_delay function: modparam("uac", "reg_random_delay", 60) I would expect that this would spread the registrations over about a minute but in reality the registrations are spread as follow: Starttime / Registrations 21:59:14 151 21:59:15 166 21:59:16 127 21:59:18 60 21:59:22 35 So Kamailio is started at 21:59:14 and initiates 151 registrations, 1 second after start another 166 2 seconds after start another 127 4 seconds after start another 60 8 seconds after start the last 35 In reality it looks like some increment is applied instead of calculating a random starting offset for each outbound registration? Is there any solutions to this issue available? Best regards, Ivo Vastert

rtpengine : question about RTP/RTCP multiplexing (RFC 5761) and demultiplexing
by Abdoul Osséni 16 Aug '17

16 Aug '17

Hello All, I read rtpengine can multiplex and demultiplex RTP/RTCP. Cf.https://github.com/sipwise/rtpengine Example: UAC -> Kamailio + rtpengine -> Asterisk UAC and Asterisk don't support RFC 5761. Only rtpengine does. Does this mean that uac must be compliance with RFC 5761 if I want multiplex and demultiplex RTP/RTCP between UAC and rtpengine? Thanks. Abdoul.

Kamailio 4.3.4: receive_msg(): no via found in reply
by Grant Bagdasarian 15 Aug '17

15 Aug '17

Hello, We're testing kamailio 4.3.4 with two kamailio's communicating with each other. One of them is a gateway with rtpengine at the carrier side, the other is a basic sip router. When calling a destination and cancelling the INVITE a 487 is received from the carrier and directly ACK'd by the first kamailio and in turn is forwarded to the second. But the 487 response received by the 2nd kamailio doesn't have a Via header which results in kamailio printing the error: receive_msg(): no via found in reply. Any ideas why the forwarded 487 doesn't contain a Via header and how to fix this? Note: IP's are changed. Carrier: 10.0.0.1 Kamailio 1: 10.14.0.1 Kamailio 2: 10.14.0.2 U 10.0.0.1:5060 -> 10.14.0.1:5060 SIP/2.0 487 Request Cancelled.

Reinvite, rewrite reply SDP?
by Yu Boot 15 Aug '17

15 Aug '17

Finally I find a root of a problem with my T.38 reinvites. A->(NAT)->Kami->PSTN When NATted caller does reinvite, and remote side answers with 200 OK+SDP, Kami (why?) doesn't rewrite SDP for its own IP (so NATted caller can receive RTP) and leaves remote's IP as media address, so of course there is no RTP/UDPTL. All other NAT related stuff works fine. Even if remote side sends me T.38 reinvite first, everything works properly. Config file is default from Kami sources. Any ideas?

RTPEngine recording
by Alex Balashov 14 Aug '17

14 Aug '17

I have gathered that RTPEngine has recently, or perhaps some time ago, evolved a recording feature set: https://kamailio.org/docs/modules/5.0.x/modules/rtpengine.html#rtpengine.f.… Does anyone have any experience using it with Kamailio? How does it work? Any gotchas or pitfalls? It looks like recording is done via a separate daemon specifically for that purpose. Does it emit directly in a playable format, or more or less just dump the raw, RTP-encapsulated frames? -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

DNS Geo Location Kamailio servers, registration and routing
by Sadeesh Radhakrishnan 14 Aug '17

14 Aug '17

We have kamailio servers that do DNS-Geo-Location on different locations, using same domain name. So the users from a country will be preferred to his nearby server by DNS routing. Similarly users from different countries will be registering to their nearby kamailio sip servers. All the servers share a common user location table on database. Now the users are getting registered fine, with no issue. We want the users at one location should be able to call user@other-location using the user location contact information. When we tried, the INVITE is sent on common domain name and that reverse resolves dns to same server and gets a 404 not found. I need some suggestion / ideas in order to make it happen. Thanks

Inconsistency in sems v1.6 installation: sems.conf is missing
by leslie mekiyess 14 Aug '17

14 Aug '17

For some reason, the installation creates the etc directory under the /usr/local/etc/sems/ : make[2]: Entering directory `/usr/src/sems-1.6.0/apps/conf_auth' mkdir -p **/usr/local/etc/sems/**etc**/** installing conf_auth.conf make[2]: Leaving directory `/usr/src/sems-1.6.0/apps/conf_auth' Then at the make install ends the following is printed: *** install complete. Run SEMS with *** *** /usr/local/sbin/sems -f /**usr/local/etc/sems/sems.conf** At bottom libe, while following the spain document instructions, I figured out that the sems.conf wasn;t created at the /usr/local/etc/sems/ path. I can create a new one or even copy this one found : /usr/src/sems-1.6.0/apps/mobile_push/load_test/sems_cfg/core/etc/sems.conf but I am afraid of further files/directory inconsistencies. Any assistance is very appreciated.

Carrierroute, fallback, reinvites
by yu＠yu-boot.ru 12 Aug '17

12 Aug '17

Hello. Trying to implement fallback route for carrierroute and got sick to make reinvites working correctly. Until fallback route triggers, everything is OK. Anyone has working config for that purposes (NAT traversal, reinvites, carrierroute ), please? And abstract question - is it generally a good idea to implement a simple softswitch (not PBX like Asterisk) like Yate or Freeswitch with Kami? Now I just want to learn Kami and learn SIP deeper in general.

Dispatcher call id hash for server side invite
by Ryan Wagoner 11 Aug '17

11 Aug '17

For a call invite from a phone to an load balanced asterisk server farm I can use ds_select_dst with hash over callid for the algorithm. What I don't understand is what happens for a server side invite. Say user A calls user B. The server will send and invite to user B's device. User B's device will reply and ds_select_dst won't have the call id hash so it will choose a random server, which might not be the server sending the invite. How do I mark these server side invites so the call hash is known by kamailio? Or am I thinking about this the wrong way? Thanks, Ryan

My dialplan rule: ============== MariaDB [kamailio]> select * from dialplan; +----+------+----+----------+-----------+-----------+-----------+----------+-------+ | id | dpid | pr | match_op | match_exp | match_len | subst_exp | repl_exp | attrs | +----+------+----+----------+-----------+-----------+-----------+----------+-------+ | 1 | 1 | 1 | 1 | ^000$ | 0 | ^000$ | | | +----+------+----+----------+-----------+-----------+-----------+----------+-------+ But the prefix 000 is not replaced.

Kamailio: how to route RTP media directly to endpoint
by wsotest.512 10 Aug '17

10 Aug '17

Hi all, We have usual config Kamailio + Asterisk where Kamailio play as sip and rtp proxy. Kamailio have public IP, asterisk - no. All calls between clients now going like that: UserA ---sip--> Kamailio --> Asterisk --> UserB \-rtp--> Kamailio (rtpproxy) --> Asterisk --> UserB All clients of course from Internet and behind Nat. Main problem is amount of traffic going through Kamailio and Asterisk. We need to pay for every additional GB behind limit in tariff plan to hosting provider. So we decided to try route all rtp traffic between users directly. UserA ---sip--> Kamailio --> Asterisk --> UserB \-rtp--> --> --> UserB Is it possible at all? Maybe someone already did it . -- BR, Alex

IMPORTANT: acc module - SQL define removed and diameter code relocated
by Daniel-Constantin Mierla 09 Aug '17

09 Aug '17

Hello, I just pushed a bit of clean up to acc module, therefore be aware of following changes: 1) the define conditions on SQL_ACC were removed -- this was enabled for more than 10 years and only made the code look complex and hard to follow up its logic. 2) the code related to DIAMETER accounting was relocated to acc_diameter (new) module. It was a consistent size of code that was not enabled for sooo... long. It is now a dedicated module, similar to acc_radius. The diameter accounting code, even a new module now, is in the same stage, compiling but not tested, in pair with auth_diameter module, it may work, but very likely not. In summary, what's important for those using the acc module -- it offers the same functionality as it was enabled by default in the past 10 years or more, only the unused code was relocated. It offers the functionality of writing accounting records to syslog and sql databases. The acc module is now slimmer, only with the code that it needs, therefore easier to maintain and enhance for the future. Hopefully, there was no side effect with this update -- anyhow, if you find any issue, just open a bug report on github project.

RFC: Moving misc/obsolete/ to its own git repository
by Daniel-Constantin Mierla 09 Aug '17

09 Aug '17

Hello, trying to make the git repository a bit slimmer and avoid unuseful indexing of unused modules, I am considering to move misc/obsolete to its own github repository (planned to be named kamailio-obsolete). The initial idea was to keep there modules that were duplicated or no longer maintained, just in case someone will come later and wants to revive it. However, iirc, it is more than 4 years and nobody touched them, so very likely it requires a bit of work to revive any of them, so a fresh re-import will be the same from an external repository. If anyone still wants to keep them in the main kamailio repository, respond on the mailing list and present the benefits. If not, I will do the operation in the next several days.

Core crash in del_lump() "offset exceeds message size" when using subst() inside tm:local-request route.
by Cody Herzog 08 Aug '17

08 Aug '17

Hello. Inside the tm:local-request route, I am trying to modify the body of outgoing NOTIFY messages using the subst_body() function. Things seem to work fine most of the time. The NOTIFY messages are correctly modified. However, I will very rarely hit a crash. I can force the crash to happen more quickly by stress testing with thousands of NOTIFY messages being modified. Is it safe to call subst() or subst_body() inside the tm:local-request route? If not, is there another way I can modify the outgoing NOTIFY messages safely? Note that I am also calling append_hf() inside the same tm:local-request route, but that has been working for a very long time without causing any problems. Could there be some kind of bad interaction between append_hf() and subst_body()? Strangely, it seems like using subst() makes the crash more likely to happen. For some reason, subst_body() seems to be more robust. Here are the logs I see: --------- Jul 28 10:57:40 SIPCOMM-VEGAS-TEST /usr/local/sbin/kamailio[2476]: CRITICAL: <core> [data_lump.c:292]: del_lump(): offset exceeds message size (1625 > 1194) aborting...

kamailio + dispatcher asterisks + pstn gateways
by Aidar Kamalov 08 Aug '17

08 Aug '17

Hello, Whats the best way to provide subject? Now I have central kamailio server and (asterisk "media" servers + asterisk pstn gateway in different cities). Kamailio default config with some changes in route[LOCATION] if (!lookup("location")) { $var(rc) = $rc; route(TOVOICEMAIL); t_newtran(); switch ($var(rc)) { case -1: xwarn("Contact $rU not registered. Forwarding call to dispatcher"); append_hf("X-External: true\r\n"); $rU = "00"+$rU; break; case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } ...... # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } if(!ds_is_from_list()) { route(DISPATCH); } route(RELAY); So all calls going to asterisk server. Not local calls with 00 prefix. And asterisk context: context kamailio { _X. => { Noop(CALL to kamailio user ${EXTEN}); Dial(SIP/${EXTEN}@${SIPDOMAIN},60,RTt); Hangup; } _00X. => { Noop(CALL to external user ${EXTEN}); Dial(SIP/PSTN-SERVER/${EXTEN:2},60,RTt); Hangup; } } Is it right way? Maybe any better approach? How to keep route logic at kamailio, but use dispatcher asterisk to proccess the calls to pstn(all endpoints at one city to pstn asterisk at this city. In others city there are other pstn gateways)? -- Aydar A. Kamalov

Kamailio Server not relaying any message

Hi, I have an ongoing issue with kamailio...my softclient registered with kamilio originates a call which gets routed to another switch from kamilio and that switch terminates the call to B party side. Now once calls is established, B party sends BYE messages or (any re-INVITE during the dialog) which comes to the kamailio but kamailio is not relaying it to the A party...Can someone please help in this regard.

Some Fault messages I am trying to clear up

Hi list people: When using Siremis with Kamailio, I see this error: First Fault [2017-08-07 22:55:17 (GMT)] An exception occurred while executing this script: Error message: #256, Unable to location template file system_internal_error.tpl.

Also: during the installation, I, using the install script, added a number of tables to the MySQL server. However, it seems I am missing a few columns in a couple of the tables. Is there some sort of system sanity script that will check the database for all the required tables and required columns?

Question regarding t_check_trans()
by Joe Baran 07 Aug '17

07 Aug '17

Probably an elementary question, but we're relatively new at digging into the details. We are trying to understand the following block of config code and have a question or two. Our assumption is the t_precheck_trans() function tells us whether another packet has arrived already as a retransmission. However, we're not clear on what the t_check_trans() is doing assuming the condition is true. Any direction on this? Thanks. route[CHECK_RETRANS] { # handle retransmissions if(t_precheck_trans()) { t_check_trans(); exit; } } Joe Baran

Pull Request or Issue? - coredump in case no contentLengthHdr present in REGISTER

Hi all, We have identified an IMS related issue, when the "Content-Length" header is missing in REGISTER request. It's a missing null pointer check in file modules/ims_auth/utils.c We are using Kamailio 4.4.5 for this purpose and we would need a fix in that release. I'm not sure, how to proceed now? Should I just create an "Issue" at GitHub, or is it possible for me to create a "Pull Request" at GitHub (would be less effort for you, I guess).

Fwd: kemi lua routing block as route in standart cfg

thx. I just thought that it's possibe to concatenate both engines together. So this is my last question regardng kemi: Main goal why i still not use kemi at the my projects is a: TBD: the options for specific event_route blocks. Meanwhile, should work using hybrid configuration with request_route/reply_route/… in embedded interpreter and the other routing blocks in native kamailio.cfg. As i uderstand it is not possible to use event_route in a kemi. only native.

route[LOCATION] is it bug?

But If i put xlog("AAAA") or xwarn in route[LOCATION] in if (!lookup("location")) block (default kamailio 5.0.2 config) calls to other destination goes through dispatcher to asterisks. I cant't understand WHY? :( (sorry for my bad English) route[LOCATION] { #!ifdef WITH_SPEEDDIAL # search for short dialing - 2-digit extension if($rU=~"^[0-9][0-9]$") { if(sd_lookup("speed_dial")) { route(SIPOUT); } } #!endif #!ifdef WITH_ALIASDB # search in DB-based aliases if(alias_db_lookup("dbaliases")) { route(SIPOUT); } #!endif $avp(oexten) = $rU; if (!lookup("location")) { xwarn("method ($rm) r-uri ($ru)\n"); ################## HERE ########################## $var(rc) = $rc; route(TOVOICEMAIL); t_newtran(); switch ($var(rc)) { case -1: case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } if(!ds_is_from_list()) { route(DISPATCH); } route(RELAY); exit; } -- Aydar A.

Hi All, We are seeing that Kamailio's nat_helper_module function of add_rcv_param(), inserts " (quote) mark to some of the SIP headers (as below in the contact header in sip 200 OK response) Contact: <sip:172.70.1.2:5060;bnc;received="sip:118.107.184.242:25090 ">;expires=172 We got few SIP UAs that are complaining about the quote mark inclusion in contact header and responding back with SIP 400 bad syntax status code. Requesting views / suggestions from community about this behavior of kamailio and any workarounds available. Cheers Arslan

Hello, I'm trying to use a htable to reroute some numbers but when i'm trying to use kamcmd to add a entry where the element name is a number instead of a string i get a 500 error kamcmd htable.seti force_number 1234 1 error: 500 - Not enough parameters (htable name, key name and value) Also with quotes i get the 500 error: kamcmd htable.seti force_number "1234" 1 error: 500 - Not enough parameters (htable name, key name and value) But this works: kamcmd htable.seti force_number a1234 1 Is there a way to escape this so i can use a number as element name? Regards, Jan Hazenberg

Kamailio example configuration: auth section incomplete?
by George Diamantopoulos 02 Aug '17

02 Aug '17

Hello again, Still getting familiar with kamailio, and I'm wondering about the AUTH route in the example configuration file. Here's a reducted-simplified version of it for reference (from git master, without IP AUTH and comments): ______________________________________________ route[AUTH] { if (is_method("REGISTER") || from_uri==myself) { if (!auth_check("$fd", "subscriber", "1")) { auth_challenge("$fd", "0"); exit; } if(!is_method("REGISTER|PUBLISH")) consume_credentials(); } if (from_uri!=myself && uri!=myself) { sl_send_reply("403","Not relaying"); exit; } return; } ______________________________________________ So the way I see it, what happens is the following: * All REGISTERs will be challenged * All SIP messages with kamailio's aliases in the "From" header URI will be challenged * All SIP messages with no reference to kamailio's aliases in both R-URI and "From" header URI will be dropped The question is, what about messages that do not enter either of the two conditionals? For example, I expect the following to be very common: * Method: INVITE * R-URI: myself * From: username@"UAC's local IP address" (not myself) * To: myself So in the example above, the auth route will return without either having challenged or dropped the request, am I correct? This is because: * For the challenge: Method is not REGISTER and "From URI" is not one of kamailio host's aliases (cumulatively) * For dropping after sending 403: "From URI" is not one of kamailio's host's aliases (which calculates to true) but R-URI is "myself" So I'm guessing we're expecting the challenge to come from elsewhere in cases like the example above? Or is there something else I'm missing here? Thanks! BR, George

is_first_hop
by Nicolas Breuer 02 Aug '17

02 Aug '17

Hello, I tried to understand the concept of first hop in "replies" In the documentation ; For incoming SIP replies, it means that top Record-Route URI is 'myself' and source address is not matching it (to avoid detecting in case of local loops). Note that it does not detect spirals, which can have the condition for replies true also in the case of additional SIP reply receival. Here's an incoming reply received on 217.112.180.10. Via: SIP/2.0/UDP 217.112.180.10;branch=z9hG4bK723f.db3510ce15ac9bb6467e115ecc2fe2a7.0. Via: SIP/2.0/UDP 217.112.180.9;rport=5060;branch=z9hG4bK723f.741041093fec570744afcf44f2194581.0.

SIP Proxy/Redirect
by Aaron Tecey 02 Aug '17

02 Aug '17

Hi All, Hoping for some help as a beginner. I need to configure a sip proxy server so that it redirects all processes to a freeswitch server on another network. SIP UACs are on an isolated network and have only a connection to the sip proxy. All I need the proxy to do is pass on all requests to the the freeswitch UAS on a different network, as it will handle registering etc. Is there a basic setup for this type of behaviour? Many thanks, Aaron

Reverse DNS lookups inside Kamailio
by Sebastian Damm 02 Aug '17

02 Aug '17

Hi, for a project I need the option to do a reverse lookup of an IP address and use the value from it in a variable. As far as I could see the ipops module only allows SRV and A record lookups. Is there anything I missed? And if there is nothing inside Kamailio, how could a good approach look like? Thanks in advance, Sebastian

T.38 fax, rtpproxy, re-invite
by Yu Boot 02 Aug '17

02 Aug '17

Hello. I'm using almost default kamailio.cfg with nathelper, rtpproxy, PSTN dialing and other default features. I have following scheme: FXS gateway -> (NAT) -> Kamailio -> FreeSwitch Voice calls work perfectly, no one-direction sound and so on. But with fax machine there was a problem. In wireshark I saw UDPTL from FS to Kamailio IP, and no UDPTL at all to FXS gw. I've guessed that something's wrong with a re-INVITE request processing in Kamailio. I've added this to WITHINDLG route: else if ( is_method("INVITE") ) { record_route(); } And problem was magically solved, T.38 now works OK. Is this OK solution or this may break something elsewhere? Thanks.

Usleep on Reply
by Nicolas Breuer 01 Aug '17

01 Aug '17

Hello All, I'm trying to code something on the on_reply part to do something if I receive a 183 ( Session in progress ) , followed immediately by a "180" I tried to sleep 1 second the 183 and recheck if I received before a 180 but seems the "sleep" function sleeps everything ( also the received 180 ) Is a developper can confirm that ? The goal is to detect if a 180 follow the 183.

uac_auth credentials
by Volkan Oransoy 01 Aug '17

01 Aug '17

Hi all, I use UAC module for remote registrations on my proxy box. There is no problem with incoming calls and I successfully register and receive calls. I have a Freeswitch box behind this proxy box and I want my proxy to add authorisation headers for outgoing calls transparently. I already have credentials at uacreg table for remote registrations. Is it possible use same credentials at uac_auth() function? Or should I run SQL to retrieve necessary fields to feed uac_auth? Thanks! /Volkan

Need help to log the call trace/flow in file
by amit Kumar 01 Aug '17

01 Aug '17

Hi Developers, I need help to log the call flow in a file. Our purpose to have only one entry per call in a file based system at the end of the call. For example: CALL-ID TO FROM START TIME END TIME .... MISSED COMPLETED 1 sip:1@abc.com sip:100@abc.com 2017-07-28 18:29:14 2017-07-28 18:29:14 yes no 2 sip:2@abc.com sip:100@abc.com 2017-07-28 18:29:14 2017-07-28 18:29:14 no yes 3 sip:3@abc.com sip:100@abc.com 2017-07-28 18:29:14 2017-07-28 18:29:14 no yes I have gone through various trace module, but its appear that all module record the call flow/logs in database. ie siptrace,acc,dialoge module. Could you please help me to log the information. one of the approach I have thought to store all the variable in AVP variables in request_route,failure_route,on_reply route..etc For ex. $avp(from)=$fu; $avp(to)=$tu; $avp(starttime)=startime $avp(endtime)=endtime etc... //log at call end in a seperate logs file and xlog("LOG_INFO",$avp(from),,$avp(to),$avp(starttime),$avp(endtime)) Please let know if this approach is correct or any other way to achieve this, Thanks, Amit

Weird issue with kamailio relaying messages to itself
by George Diamantopoulos 31 Jul '17

31 Jul '17

Hello all, I have been toying with kamailio lately, and I thought I had gotten to the point where I had a mostly working (tm) prototype. I gave it a test drive with some real calls, however, and an issue manifested at least once, where homer received packets originating from the kamailio host, and whose destination was also the kamailio host. The dialog this manifested in is a generally problematic one, with many retransmissions occurring because of slow database access (I haven't implemented htable caching yet). No packet capture over the network is actually taking place, I'm copying everything to homer with "trace_mode"set to 1. Homer shows these messages like in the screenshot: https://imagebin.ca/v/3VGJAmovRBmo. Here's an example of a packet: 2017-07-28 14:32:29 +0300 : 2.3.4.5:5060 -> 2.3.4.5:5060 INVITE sip:1234567890@kamailio-server.org SIP/2.0 Record-Route: <sip:2.3.4.5;lr;ftag=as491cec82> Via: SIP/2.0/UDP 2.3.4.5;branch=z9hG4bK0cf.07799e3eb71f33a9ef91178ac760ebd2.0 Via: SIP/2.0/UDP 2.3.4.5;branch=z9hG4bKsr-BnCVyrWoUladI14pU7Pry-Pzy-ONy-VSQ74NU7HzeYazq2nFU2Oc5FIWiGIKq-HXex1oONpam-C6IrIXkr4FQxZRh7sM Max-Forwards: 69 From: <sip:subscriber@5.4.3.2:5061>;tag=as491cec82 To: <sip:1234567890@kamailio-server.org> Contact: <sip:2.3.4.5;line=sr-eNC05xhKefQnON1EglFrOkF0OfpzV2s9UzM9UXMNQXMn5-B0Q-s*> Call-ID: 4e5d22c3369704b97d866c8d0f3798f8@192.168.201.2:5061 CSeq: 103 INVITE User-Agent: Asterisk PBX 11.13.1~dfsg-2~bpo70+1 Date: Fri, 28 Jul 2017 11:32:24 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Remote-Party-ID: "9876543210" <sip:9876543210@192.168.201.2 >;party=calling;privacy=off;screen=yes Content-Type: application/sdp Content-Length: 500 v=0 o=root 242468242 242468243 IN IP4 172.17.130.13 s=Asterisk PBX 11.13.1~dfsg-2~bpo70+1 c=IN IP4 172.17.130.13 t=0 0 m=audio 59426 RTP/AVP 18 101 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:50 a=sendrecv a=rtcp:59427 a=ice-ufrag:hffIoy6x a=ice-pwd:nXB8ip7Qz8ZG5yyZRr97kGJbej a=candidate:igct4zWHEzhGCjWc 1 UDP 2130706431 172.17.130.13 59426 typ host a=candidate:igct4zWHEzhGCjWc 2 UDP 2130706430 172.17.130.13 59427 typ host Can something like this be triggered by misconfiguration in the routing scripts?

Rate limiting

Hello, I plan to add some rate limiting in the Kamailio. I'm already using Pike to rate limit based on the source IP. But in this case, i want to do the rate limiting per customer(regardless of the source IP), I can identify the customer based on a custom header in the INVITE, idea is to limit the customer to 'x' number of requests per second.

Configuration to use rtpengine for SRTP
by David Cunningham 31 Jul '17

31 Jul '17

Hello, We're configuring Kamailio 4.2 with rtpengine to act as a midpoint between a telephone using TLS/SRTP and Asterisk. There are examples out there for TLS/SRTP with WebRTC, but we're using a plain hard phone, not WebRTC. Would anyone be able to point us towards a Kamaiio configuration which: a) Tests if the destination phone (stored using usrloc) uses TLS. b) Sends RTP for calls to a TLS phone to rtpengine to be encrypted. We can assume all phones using TLS want to use SRTP. Thanks very much in advance. -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 Australia: +61 (0) 2 8063 9019

why is tcp_no_connect disabled by default
by Vik Killa 27 Jul '17

27 Jul '17

I'm trying to understand the scenario when `tcp_no_connect` should ever be set to `no`. Kamailio comes with `tcp_no_connect=no` by default which means it will try (and seemingly always fail) to create an outbound tcp connection when a UAC's tcp connection is lost. This in-turn could start building up the tcp write queue and can be disastrous at scale. So why would this setting (`tcp_no_connect=no`) ever be useful? Thanks

Re: [SR-Users] kamcmd uac commands not working
by Gertjan Wolzak 26 Jul '17

26 Jul '17

Hello Daniel, Yes, that are the parameters I've set. But just found out why the kamcmd uac commands were not working. Looks like you have to have a succesfull registry to be able to give the uac.reg_xxx command. Once I had a succesfull registration, the command works. So, I will continue to learn.. Thanks.

Fwd: kamcmd uac commands not working
by Gertjan Wolzak 26 Jul '17

26 Jul '17

Hello All, Been a while, glad to be back. I started working with the kamailio 5.0.2 version, specificly with the UAC module trying to register accounts with another B2BUA. When I give the command kamcmd, I end up in de kamcmd cli. The command ctl.connectsion shows me the number of connections, when I give the command uac.reg_dump, the result is an error: 500. Below the cli dump... I'm going to assume I have an error in my config, but I don't understand where... I've looked at the uac module documentation and think I have set the parameters correctly. kamcmd 1.5 Copyright 2006 iptelorg GmbH This is free software with ABSOLUTELY NO WARRANTY. For details type `warranty'. kamcmd> ctl.connections 1 kamcmd> uac.reg_dump error: 500 - command uac.reg_dump not found kamcmd> # Uac parameters modparam("uac","restore_mode","auto") modparam("uac", "restore_dlg", 1) # ----- tm params ----- # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 3) # default retransmission timeout: 30sec modparam("tm", "fr_timer", 30000) # default invite retransmission timeout after 1xx: 120sec modparam("tm", "fr_inv_timer", 120000) # ----- rr params ----- # set next param to 1 to add value to ;lr param (helps with some UAs) modparam("rr", "enable_full_lr", 0) # do not append from tag to the RR (no need for this script) modparam("rr", "append_fromtag", 1 # Dialog parameters modparam("dialog", "enable_stats", 0) modparam("dialog", "db_url", DBURL) modparam("dialog", "dlg_flag", 4) Does anyone see an error I've made, or has some information for me to look at...? Or maybe I did not provide enough information... Tips would be appreciated. Rgds, Gertjan

xavp questions (variables in root/branch)
by Vasiliy Ganchev 25 Jul '17

25 Jul '17

Hi, community! I have a question regarding xavp usage. according to docs, xavp has format: $xavp(root=>branch)="value"; I want to use "root" and "branch" - variables. (as it is implemented with AVPs - the id there, can be variable) e.g.: ... $var(root_key) = "root_1"; $var(branch_key1) = "key_value1"; ... $xavp($var(root_key)[0]=>$var(branch_key1)) = "some_value"; ... Playing around with the script - I found that it is currently impossible (tested with 4.2.5 and 5.2.0 versions). Kamailio interprets variables in "root" and "branch" as static strings. Walking through the mailing list history, I have an impression that xavp are originally designed to operate only with constant keys. The question is: is it planned to add functionality with variables as "root" and "branch" components? Thanks in advance for the answers! Best regards -- View this message in context: http://sip-router.1086192.n5.nabble.com/xavp-questions-variables-in-root-br… Sent from the Users mailing list archive at Nabble.com.

I_SCSCF_select function dont return the next SCSCF in IMS network!!!
by Mojtaba 25 Jul '17

25 Jul '17

Hello, Today i have a strange problem in IMS network. All nodes (pcscf,icscf,scscf and hss) are configured in independent server. My domain is default(open-ims.test) Now when i want to register bob(a)open-ims.test, I get this error from ICSCF: 500 Error in request. When i saw the log files, i found the icscf could not found the next node(scscf) in registration path. As i defined prefered scscf_uri in configuration file, Why the icscf, could not found the scscf? The dns server works correctly and i have ping of scscf.open-ims.test from icscf node. When i trace the diameter packets, the icscf connect to hss successfully but dont send UAR to hss while registration proccess!! It's strange. Please let me know why i have this problem, Thanks With Regards. -- --Mojtaba Esfandiari.S

TR: Failure Mode
by Nicolas Breuer 24 Jul '17

24 Jul '17

Hello, Some help here is needed # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 3) I test a call with two branches. 1st branch received a 408 timeout error 2nd branch received a 486 busy. Normally the failure route should be with the 486. NOTICE: <script>: Failure route -----2---1--408---- We can see the 408 is the winning reply but I understood from the documentation that if Failure reply mode is "3" , the winning reply is always the reply from the last branch :) It's a problem because if the 1st is timeout (because down), the second is OK but callee is busy ; we don't send the right reply to the caller

path use_received not working?
by Iskren Hadzhinedev 23 Jul '17

23 Jul '17

Hello, I have a kamailio proxy in front of FreeSWITCH. Whenever FreeSWITCH initiates the dialog (e.g. sends an INVITE), kamailio doesn't use the 'received' parameter and it forwards to the RFC1918 IP address. The initial INVITE from FreeSWITCH has the following headers: To: <sip:1001@192.168.1.200:5063> Route: <sip:1.2.3.4>;lr;received=sip:5.6.7.8:5063 Where 1.2.3.4 is the kamailio public IP and5.6.7.8 is the public IP of the UAC behind NAT. I have modparam("path", "use_received", 1) in my config file and to my understanding that should be sufficient to route to the proper IP, but kamailio keeps sending INVITEs to 192.168.1.200. Can anyone tell me what am I missing? Thanks! Kind regards, Iskren

Re: [SR-Users] Problem with IPv4-IPv6 media bridging using RTPengine

The UDP protocol of the rtpproxy module should work with rtpengine, but not many people are using it, so it's always possible that some bugs creep in. I'll look into it anyway, but in the long run, it's much preferable to switch to the rtpengine module. Cheers ########################## Hello Richard, thank you very much for your answer. I will try to use rtpengine module. As I can see from logs, kamailio is sending correctly data to rtpengine but rtp engine failed to parse IPv6 address from SDP body. I'm sending flags to rtpengine according to the howto from link I've posted in the original post. This is the part of the config: if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB) || isbflagset(FLB_V4V6))) return; if(isbflagset(FLB_V4V6)) { if(af==INET6) { rtpproxy_manage("FAEI"); } else { rtpproxy_manage("FAIE"); } } else { if(af==INET6) { rtpproxy_manage("FAEE"); } else { rtpproxy_manage("FAII"); I'm not sure if I need to inform rtpengine that in SDP body will be IPv6 address.

kamailio 5.0 with asterisks
by Aidar Kamalov 20 Jul '17

20 Jul '17

Hello! I'm new with kamailio, so may be don't understand some basic. I'm tryin to load balance asterisk servers with kamailio and dispatcher module. My ip phones registered at kamailio, for example: [root@sipchel ~]# kamctl ul show 101 { "jsonrpc": "2.0", "result": { "AoR": "101", "Contacts": [{ "Contact": { "Address": "sip:101@192.168.2.62;line=4733c4bfa459eea", "Expires": 2953, "Q": -1, "Call-ID": "1361221648", "CSeq": 136, "User-Agent": "Linphone/3.6.1 (eXosip2/3.6.0)", "Received": "[not set]", "Path": "[not set]", "State": "CS_SYNC", "Flags": 0, "CFlags": 0, "Socket": "udp:192.168.10.54:5060", "Methods": -1, "Ruid": "uloc-596f5abc-2ce5-2", "Instance": "[not set]", "Reg-Id": 0, "Last-Keepalive": 1500530337, "Last-Modified": 1500530337 } }] }, "id": 15024 } I have realtime asterisk server. [root@sipchel ~]# kamctl dispatcher dump { "jsonrpc": "2.0", "result": { "NRSETS": 1, "RECORDS": [{ "SET": { "ID": 1, "TARGETS": [{ "DEST": { "URI": "sip:192.168.4.16", "FLAGS": "IX", "PRIORITY": 0 } }, { "DEST": { "URI": "sip:192.168.10.47", "FLAGS": "AX", "PRIORITY": 0 } }] } }] }, "id": 15087 } So I want if 101 call to 102 it will process by asterisk(for call recording and other features). Now if I call from 101 to 102 kamailio will forward to asterisk and asterisk dialplan cannot find that extesion(as expected, because it is not registed on asterisk) [kamailio] exten => _1XX,1,Dial(SIP/${EXTEN}) exten => _1XX,n,Hangup If I change dialplan to Dial(SIP/KAMAILIO/${EXTEN}) call wil return to kamailio, but kamailio send it back to asterisk... I hope I explained correctly, my English is terrible. Is my screnario proper? How this usually done? Should I forward sip registrations to asterisks?

Hi, I'm trying to integrate Google cloud speech recognition v2 in it. I can get the audio recorded, have created Service key and API key but whenever I try to access it, I just get 403 access denied. I am at my wits end here. Has anybody tried it ? were you successful ? Could you please guide me how to do it ? I'll be grateful to you if this works ! -- Warm Regds. MathuRahul

Problem with IPv4-IPv6 media bridging using RTPengine
by Ismir Saljic 19 Jul '17

19 Jul '17

Hello, I've issue with bridging media between IPv4 and IPv6 clients. IPv4-IPv4 and IPv6-IPv6 calls are working without issues. I'm using kamailio 4.4.2 and configuration according to: http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6 SIP signalling is working without issues,but media addresses in SDP are not rewritten correctly. The server is on amazon AWS and both kamailio and RTPengine are on the same server. RTPengine is running using these options: /usr/sbin/rtpengine --interface=privateIPv4!publicIPv4 --interface=GlobalIPv6 --listen-udp=127.0.0.1:22222 --tos=184 --pidfile=/var/run/rtpengine.pid --log-level=6 --log-facility=daemon In case of IPv4-IPv6 call, INVITE message contains correct IPv4 address but 200 OK response to the caller still contains IPv6 address of the callee in SDP body instead of IPv4 address of the server/RTPengine. This is the log during generation of the 200 OK response. Seems that RTPengine failed to parse IPv4 address from SDP body.

dns failover and branches
by Juha Heinanen 19 Jul '17

19 Jul '17

If Request-URI hostpart is a domain name with more than one SRV record, it appears that each SRV destination creates its own Kamailio branch. If branch route is set before t_relay(), it is executed only on the first SRV destination. If the first SRV destination fails, Kamailio tries automatically the second one, but any branch flags set in the branch route are lost. What is the simplest way to make Kamailio preserve the stuff set in the branch route for all SRV destinations? -- Juha

about rtpengine-[offer-answer] via-branch flag
by Juha Heinanen 18 Jul '17

18 Jul '17

rtpengine-offer function documentation tells this about via-branch flag: via-branch=... - Include the “branch” value of one of the “Via” headers in the request to the RTP proxy. Possible values are: “1” - use the first “Via” header; “2” - use the second “Via” header; “auto” - use the first “Via” header if this is a request, or the second one if this is a reply; “extra” - don't take the value from a header, but instead use the value of the “extra_id_pv” variable. This can be used to create one media session per branch on the RTP proxy. When sending a subsequent “delete” command to the RTP proxy, you can then stop just the session for a specific branch when passing the flag '1' or '2' in the “rtpengine_delete”, or stop all sessions for a call when not passing one of those two flags there. This is especially useful if you have serially forked call scenarios where the RTP proxy gets an “offer” command for a new branch, and then a “delete” command for the previous branch, which would otherwise delete the full call, breaking the subsequent “answer” for the new branch. Is the note about "serial forking" correct or should it be about "parallel forking" instead? In case of serial forking, it would not matter if the whole call is deleted, because a new offer would be issued for the next branch. Or perhaps I just don't understand the meaning of the note? -- Juha

rtpengine: Failed to open UDP control connection port
by David Cunningham 17 Jul '17

17 Jul '17

Hello, We're using Kamailio 4.2.1 with rtpengine 5.1.2.1 on Ubuntu 16.04. When running rtpengine we get this error: [1500263405.711288] ERR: FAILED TO CREATE KERNEL TABLE 0 (File exists), KERNEL FORWARDING DISABLED [1500263405.712367] CRIT: Fatal error: Failed to open UDP control connection port The first line I think is not important, but the second appears to be. It's being run as root with these options: /usr/sbin/rtpengine --interface=xx.xx.xx.xx --listen-ng=7724 --timeout=60 --silent-timeout=3600 --pidfile=/var/run/rtpengine.pid --port-min=45000 --port-max=50000 --table=0 Running "netstat -lnp | grep 7724" does not report anything listening on port 7724 already. Has anyone any ideas? Thanks in advance. -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 Australia: +61 (0) 2 8063 9019
