Well... most likely you didn't fix it, at least
not properly. There's no
such requirement to have a single RR in the 200 OK, especially only the one
from the sender's original invite.
By this logic, Kamailio can't insert it's own RR to keep itself in the
call's path. I can assure you that's not the case in reality.

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
