Hi,

I have registered an UA 12345 , which is public. In location table, I found NULL value for received. I dial any UA , irrespective to their NAT status. Call has been established but can't get audio both side. It does not use mediaproxy for audio signaling.

How to resolve this problem?

Do a full sip flow capture and analyze trhe address and port of media in SDP of INVITE and 200 OK.
