update max_while_loops in config
by Juha Heinanen 08 Oct '21

08 Oct '21

It is possible to update value of max_while_loops dynamically in config file? For example, there could be a need to increase the max in some while loop, but after the loop is done, decrease it again for other loops. There exists an rpc command to do that, but I haven't found how to do it in config file. I tried @cfg_seti.core.max_while_loops = 200; but got syntax error. -- Juha

Re: [SR-Users] t_drop_replies not working with t_suspend in failure route

Hi, We’re still using kamailio 4.4 but we’ll be migrating to 5.0 soon. Cool so it will be fixed when we migrate ! Thanks, Andreas From: sr-users [mailto:sr-users-bounces@lists.kamailio.org] On Behalf Of Federico Cabiddu Sent: vendredi 12 mai 2017 11:56 To: Kamailio (SER) - Users Mailing List Subject: Re: [SR-Users] t_drop_replies not working with t_suspend in failure route Hi, which version are you using? A similar case had been reported some months ago and it should be fixed in 5.0.

We’d like to drop the previous branches in this case. I tried using t_drop_replies() but it has no effect. The doc states that t_drop_replies() is only working if a new branch is added. And from my understanding t_suspend() adds a new branch. But is it possible that t_drop_replies() cannot be used with t_suspend()? Or am I missing something?

Roadmap to the next major release - v5.5.0
by Daniel-Constantin Mierla 16 Jun '21

16 Jun '21

Hello, it is the time to plan a bit the road to the next major release, to be versioned 5.5.0. The 5.4.0 was release by end of July 2020, therefore we are approaching the end of our usual development cycle, also during the last online devel meeting we considered the 2nd part of spring 2021 as a target time frame for 5.5. To narrow it down, I would propose to freeze the development at the end of March 2021, test during April and maybe beginning of May, then release v5.5.0. So far we have a lot of development to existing components, by the freeze date I expect 3-5 new modules to be in the repo as well. If anyone wants a different time line towards 5.5.0, let's discuss and choose the one that suits most of the developers.

Setting $conid per branch
by Marrold 14 May '21

14 May '21

Hi all, I'm currently adding a feature to our Kamailio configuration to fork calls based on user agent. To do so I'm getting the registered endpoints with reg_fetch_contacts() iterating through and matching on them, then using seturi() / append_branch() and setting the dst-uri and flags as required. However, calls are intermittently going to the wrong TCP connection, despite the logs showing the correct destination IP and port in the ONSEND route. Looking in the location table I can see each registration has a connection_id, and the debug log indicates it's finding the connection by ID: DEBUG: <core> [core/tcp_main.c:1651]: _tcpconn_find(): found connection by id: 3 Is there a way to set the conid per branch? Is it necessary? We're using kamailio 5.3.3 on Debian 10. Thanks Matthew

start_recording and stop_recording inside event_route[xhttp:request]
by Володимир Іванець 05 May '21

05 May '21

Hello! I'm testing call recording with Rtpengine. It works fine when the "record-call=on" flag is added to the *rtpengine_offer* or *start_recording* is used in the *request_route*. But I was wondering if the call recording can be managed by a separate application. So I add the following lines to the *event_route[xhttp:request]* and triggered it with an HTTP request after the call was established. The call-id value was taken from the Rtpengine log and sent with the request. * if ($hu =~ "^/CALL_RECORD_START/") {* * $var(call_id) = *"call-id=" + *$(hu{s.select,2,/});* xlog("L_DBG", "$var(call_id)"); * start_recording($var(call_id));* exit; * }* In this case, Kamailio will log errors and will not send the Rtpengine command to start call recording. *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: DEBUG: <script>: call-id=3de74068278ede4417086eb82bdf5a06@127.0.0.1:5080.0* *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: DEBUG: <core> [core/parser/msg_parser.c:89]: get_hdr_field(): found end of header* *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: ERROR: rtpengine [rtpengine_funcs.c:294]: get_callid(): call-id not found* *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: ERROR: rtpengine [rtpengine.c:2383]: rtpp_function_call(): can't get Call-Id field* Have anyone tried to call functions *start_recording* and *stop_recording* inside *event_route[xhttp:request]*? Thanks a lot!

The plan for releasing Kamailio v5.5.0
by Daniel-Constantin Mierla 05 May '21

05 May '21

Hello, after almost 4 weeks since development was frozen, it is time to plan releasing the next major stable version, respectively 5.5.0, therefore I propose to do it on Wednesday, May 5, 2021. The branch 5.5 was already created about one week ago, several doc resources were published (core/variables/transformations/rpcs/stats cookbooks, alphabetic indexes, ...). If anyone is testing an upgrade from branch 5.4 to 5.5 and encounters changes that should be done in Kamailio config, add notes about at: * https://www.kamailio.org/wiki/install/upgrade/5.4.x-to-5.5.0 Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - Online May 17-20, 2021 (Europe Timezone) - June 7-10, 2021 (America Timezone) * https://www.asipto.com/sw/kamailio-advanced-training-online/

Set $uac_req(body) to raw hex value
by Nick 03 May '21

03 May '21

Hi all, It seems in the UAC module the $uac_req(body) PV is evaluated as a string, How can I set the value of the request body of a generated request, to a raw hex value without it being interpreted as a string? Cheers, Nick

Dialog server behind proxy and ka_timer/ka_interval
by David Villasmil 30 Apr '21

30 Apr '21

Hello guys, So i have a setup where client | V (WS) [proxy (no dialog tracking)] | V [dialog server] | V [proxy (no dialog tracking)] (WS) | V client I'd like to know when any of the clients are not available (i.e.: crashed, shutdown unexpectedly. etc), so i enabled on the dialog server ka_timer/ka_interval. I see the OPTIONS going to the proxy when the call starts, and the proxy replying with 200 OK. If i shutdown the client, i see the OPTIONS still going, but the proxy is still responding. I assume the Proxy (kamailio) is simply responding to an OPTIONS message and not actually trying to resend it to the client. Is there anyway of doing this or something better to accomplish the same thing? Thanks! David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337
