[SR-Users] Kamailio drop calls with Teams

Hi
Kamailio doesn't receive any ACK from Teams. I think the problem is the
'200 Ok' that you send to Teams is not what he expected. Maybe this is
wrong:
Record-Route: <sip:FQNDIP;r2=on;lr>
Record-Route: <sip:FQNDIP:5061;transport=tls;r2=on;lr>
Try to put the registered domain (FQNDDNS) and not de IP address
Regards
