Greetings, I have a pretty odd issue that I have no idea how to resolve. We have a Sofia profile that is TLS only. It listens on 5061. This is with an upstream vendor and we want them to be able to send inbound calls to extensions without register. Our FS instance is sending back "transport=udp" and port 5060 in the Contact header of the 200 OK. Even though the invite is for TLS and the sip_profile is tls-only=true. I have attached a SIP trace and a copy of our external.xml sofia profile. I am thinking this is a Freeswitch bug - or maybe just an oddly documented "feature". Any help is really appreciated. In the sip-trace attached, you can see an INVITE followed by a Trying and then an OK. The OK has Contact information for transport=udp and port 5060, which is invalid, so the ACK never gets back to us and we retransmit the 200 OK until it expires. Thanks, Geoff
