[SR-Users] Ynt: Kamailio drop calls with Teams

Thanks at all to answer.. but I cannot get it going..

In the INVITE always I have two record-route:

Record-Route: <sip:FQDN_DNS:5061;transport=tls;lr>
Record-Route: <sip:FQDN_IP:5060;lr>

And in the 200 I have three:

Record-Route: <sip:FQDN_DNS:5061;transport=tls;lr>
Record-Route: <sip:FQDN_IP:5060;lr>
Record-Route: <sip:sip-du-a-eu.pstnhub.microsoft.com:5061;transport=tls;lr>

Could be it the problem?

I'm going crazy, and I donnot know how fix it..

Any ideas?

Thanks!!
