Hi again. I discovered something interesting with regards to the TLS connection with a specific UA when it connects via TLS. In our scenario we forward a call via Freeswitch (on another server) to another call centre provider. The UA works fine on UDP + TCP mode. However, on TLS we do not get to hear audio from the other end. (It seems that Opensips sends out a local address).
Interestingly, when I restart Opensips (3.1) and connect within a minute or so, I DO get to hear audio. But subsequent calls do NOT have any audio. This is really beyond my understanding. Is this an Opensips issue or user agent? Following is a link to level 7 log - appreciate if someone can help. There are two calls - the first one has audio, the second one doesn't. https://pastebin.pl/view/abc908c1 Much appreciate the help.
