Re: [SR-Users] Kamailio as MS-Teams SBC

20 Jan 2021

180 doesn’t need a response, as it is a provisional response TO the invite.
Same goes for 183 and all provisional responses.

A quick look to the call you pasted below seems to have connected: there’s
a 200 to the INVITE and an ACK to the 200 (which does require an ACK). Do
you see RTPs flowing to the proper IPs?

If you’re trying to integrate with MSTeams, search the web for “kamailio ms
teams” as it is riddled with little nuances, you should find pretty good
info (or search this mailing list, there’s plenty)

Some sources:

https://skalatan.de/en/blog/kamailio-sbc-teams

This one might be specially interesting to you as it regards the 200 and it
states there should only be ONE Record-Route:

http://sip-router.1086192.n5.nabble.com/kamailio-integration-with-MS-teams-…

Hope that helps.

  Hi everybody

 im going crazy in debugging inbound call

 my scenario is :

 Freeswetch PBX ---> kamailio SBC ---> Ms Teams

 my issue are:
 1 Freeswitch doesnt reply to kamailio after 180 ringing why ?
 2) kamailio forward ACK after 200 OK but MS  not accept it, (call stuck in
 setup )

 any advice are welcome !!!

 below a trace:
 Thanks You for support !

  Hi - I too have been working with RTPEngine a lot
lately.   I have needed
 to use branch mr9.1.1 - especially if you need Websocket support.

  Hello,

 I built rtpengine deb packages for debian just a few days ago and all
 went fine. I used the file mr8.5.1.5.tar.gz from the github releases of
 rtpengine project.

 However, I noticed that some past releases fail to build because of the
 tests. I had to edit a bit the Makefile to disable the tests target.

 Cheers,
 Daniel
