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.

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.

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.

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.

Thanks for the answer Sergiu, Ovidiu
I don't know your setup but I use kamailio as load balancer with FS nodes
(instead of kamailio's media proxy).
That is why I have FS node IP in the contact header of 200 OK
message which go to MS teams (it's outbound call from MS to kam).
Like we all know MS doesn't like IP address at all (in contact and
record-route). Thus I have to replace (at kamailio) FS node IP to fqdn of
trunk I use with MS.
Also I had to comment record_route() for invites from MS.
You mentioned that I should not change contact header but... really MS
ignore my 200 OK for all other cases.
Also you mentioned that you have record route header in 200 OK, but again -
MS do not ignore 200 OK only in case I have only one record route header
which was in initial INVITE from MS.
You said it is working for you. Not sure why really. May be you use
kamalio rtpproxy and that is why have correct contact at once.
As for record route header - I have no ideas why MS doesn't ignore several
record route headter in 200 OK for your case.
With my changes i got ACK from MS. And also got voice call but obviously it
is dopped in ~30 sec because kamialio do not know destination for ACK from
MS (it has kamailio FQDN in URI)
Normally with my setup, 200 OK keeps ip address of FS node and MS should
send ACK to kamilio IP but with FS IP address in URI. We all know that MS
do not respect RFC and can not do so. They just said in docs (we do not
support sip proxy).
So... Now I should to think how re-direct such ACK to FS node. Should be
possible to all this begin to be more and more complicated.
Any advice are welcome!
