Yes, sure, need to fix Record-Route. The question was how exactly :)
Well. I just fixed it by the way. 200 OK had to have only one record-route (which MS sent
in initial invite). Otherwise MS ignore it without any response.

The instructions are pretty clear in the sense that you need to fix
the Record-Route header.
You don't need to touch the Contact header for in-dialog requests/replies.

Hi guys,
Do you have some expirience with kamailio integration with MS teams ?
I follow the instructon from here
https://skalatan.de/en/blog/kamailio-sbc-teams
TLS part is configured correctly. I also got OPTIONS pings working between MS teams and
kamailio by following of this instruction. That is very good.
But... There is issues with outbound calls from MS teams to kamailo.
MS side send INVITE, kamailio responds with 180 and 200 OK, but looks like MS ignores us.
I know that I probably should use record_route_preset function here to modify Record-Route
headers to satisfy MS wishes.
But nothing helps. I also tried to modify contact header in 200 OK like it was done for
OPTIONS - no luck.
Anyone has a working example of kamailio files for MS team ?
Or at least sucessful pcap with them.
I can be wrong but looks like MS doesn't respect RFC at all.
Thanks.
Regards,
Team lead
