Yes kamailio is received ACK message but not forwarder (loose routed) to
callee. I not able to kamailio log (tow many debug info). I goes to clarify
what need to look and then reproduce.
End user is reported silence after answer.
Here
1) caller side is FreeSwitch 1.6.20
2) callee side is forked linphone

Sergey

Or it just don't receive the ACK at all?
