TL;DR: linphone does not respond to REQUESTs on persistent TLS flow to proxy
I have a linphone behind NAT without STUN/ICE in a RFC5626 situation. It maintains a persistent TLS connection to a proxy (the same as its REGISTRAR); the intention is to receive all SIP messaging on this flow. Linphone can initiate calls, receive 100, 200 OK Two issues: 1. It receives BYE but does not respond with 200 OK. It can send BYE and receive the 200 OK. 2. It doesn't respond to incoming INVITE from the other UA on this flow. The proxy is configured to reuse the persistent TLS connection for SIP messaging. Wireshark shows the proxy relaying the BYE/INVITE to linphone but there is no response. The proxy has been tested with two PJSUA UAs and works. I.e, both PJSUA UAs reuse the persistent TLS flow for all SIP messages either to respond to requests of initiate new ones.
