On my handytone, if I did not enable STUN, the * box would send the RTP data to my 192.168 address, even though I had nat=yes in sip.conf and the SIP handshake happened with my public IP. It seemed * was not properly translating (ignoring) the IP that was in the SDP into the IP that the SIP handshake happened on.
When I enabled STUN, * then started to send the RTP to the correct IP and port, but I still did not have audio. That was as far as I got and have not had time to run additional traces to see what the holdup is now.
