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.

Running Kamailio 6.0.x with rtpengine 10.5.x.x
by Sebastian Damm 03 Jul '25

03 Jul '25

Hi, I'm in the process of updating Kamailio from 5.8.x to 6.0.x, and in my last tests I noticed these error messages in rtpengine log: WARNING: [3B4A4512-7DA7-439F-97B7-78021488407B]: [core] Unknown dictionary key encountered: 'sip-message-type' We run rtpengine still with version 10.5.x.x (currently 10.5.6.3), and the update of rtpengine is a bit blocked (mainly because of the removal of iptables support requiring more changes for nftables in the background). I tracked down the changes both in rtpengine and kamailio repository, and with rtpengine 12.x it probably would work, but I'm not there yet. In this combination, does rtpengine still do what it should do? I did not notice any problems, but before our customers do, I thought I'd rather ask. Thanks for any advice, Sebastian
