Outgoing calls only from IPPhone ----- Avaya PBX ---sip----> Kamailio -----sip----> Video System-IVR Now Im trying setup rtpengine for proxy media . Kamailio has some errors by starting service. ERROR: rtpengine [rtpengine.c:3131]: select_rtpp_set(): no rtpp_set_list->rset_first Jun 06 12:07:00 zaks-sbc01-op /usr/sbin/kamailio[635658]: NOTICE: rtpengine [rtpengine.c:1815]: mod_init(): Default rtpp set 0 NOT found Missed out on something in config?

t_set_fr() sensitivity to timing when used in onreply_route
by Gianluca Merlo 10 Jul '25

10 Jul '25

Hello everyone, I am racking my brain on a peculiar behaviour with TM timers which I managed to narrow down after some trial and error, but the full implications and causes of which I still have to understand, and I am curious if anyone among the devs or other users with more knowledge than me has any clarification or suggestion to make about it. My scenario is the following, running Kamailio 5.8.5 on Debian bookworm packages 1. An INVITE for a local user is received 2. Preferences for the local user are read. The user has a certain timeout after which call forwarding should trigger. My setup aims to engage this timeout only if the user has provided a "proper" progress indication (180 or 183), and use a default value of 30 s if no progress is received. For this example, we assume this customized timeout is 10 s. 3. Standard usrloc lookup. A single location is found, behind an edge proxy (registered with Path). 4. INVITE gets sent (statefully) to the user through the edge proxy, UDP transport only. Before routing, the fr_inv_timer is set to the default value mentioned above using t_set_fr(30000). 5. The user replies with a 180. In the onreply_route, since this is the first proper progress indication, the fr_inv_timer is changed to the customized value calling t_set_fr(10000) At this point, I would expect the INVITE transaction to fail for timeout and go into call forwarding from the failure_route after the 10 s set in the onreply_route, but I am getting feedback from users that this does not always happen, and instead sometimes this happens in the 30 s set initially. I tried to reproduce the issue in a controlled setup, and the reliability of the t_set_fr() in onreply_route seems to be affected by the delay with which the 180 is received. Introducing pauses in a simulated client with sipp - With 400ms the call forwarding always triggers as expected (10s) - With 440ms I see 1/10 failures (call forwarding triggers in 30s) - With 450ms I see 5/10 failures - With >500ms I seem to get 10/10 failures So it seems like using t_set_fr() in onreply_route is sensitive to timing. Regarding this sensitivity, I noticed that 500 ms is the default retr_timer1 I am using, and changing that affects the effectiveness of the t_set_fr() call on onreply, i.e. t_set_retr(1000) allows t_set_fr() in onreply_route to be effective up to delays of 1000 ms in the 180 reception. Is this known and/or is there any workaround to get the behaviour I hoped to implement? If the limitation cannot be worked around, could it be useful to mention it in the t_set_fr() documentation? Thanks in advance for your help!

Off topic - FreeSWITCH and opus
by Calvin E. 09 Jul '25

09 Jul '25

For those who wanted to use opus but gave up due to transcoding or call recording issues, a new pull request should resolve them. This allows FreeSWITCH to properly match things like AMR-WB with 16kHz Opus, and fixes an issue with timestamp increments. https://github.com/signalwire/freeswitch/pull/2832 -Calvin E.

Registration lookup on Invite
by smartin114＠me.com 07 Jul '25

07 Jul '25

Hi, very new to this and trying to add some security for inbound invites. We only want to allow invites from users that are in the registration table, but everything gets a 403, not just an Invite from an unregistered user. if (KSR.is_INVITE()) { if (KSR.registrar.lookup("location", KSR.pv.get("$fu") < 0 )) { KSR.info("Check user registation before passing invite: " + username + KSR.pv.get("$f")); KSR.sl.send_reply(403, "Forbidden"); KSR.x.exit(); } } Any help is appreciated.

Stir/Shaken
by David Villasmil 07 Jul '25

07 Jul '25

Hello, I've seen people wondering how to implement Stir/shaken on Kamailio and OpenSIPS. It occurred to me that making a docker image would help a lot of people so I did. You can find it in https://hub.docker.com/repository/docker/davidcsi/kamailio-stirshaken/gener… and in the description you can read how it works and how to use it. Hope it helps!

node module to help writing SIP functional/integration tests
by mayamatakeshi 07 Jul '25

07 Jul '25

Over the years I have been slowly writing a node module to help me write SIP functional/integration tests: https://github.com/MayamaTakeshi/sip-lab I have been adding new features as I needed for new kinds of test but didn't have time to document it. But now I need to mentor some newcomers to the company I work for and had to do it. I asked gemini to do it for me and got: https://github.com/MayamaTakeshi/sip-lab/blob/master/DOC.md It might be of help for other people so I am sharing it.
