Hello, I have asterisk 1.6.1.1 box behind NAT. On the same local network I've SIP proxy server too. The problem appears with RTP.My provider's RTP IP addresses are public. When asterisk sends SIP invite to SIP proxy, it defines local RTP IP, but not externIP. Maybe somebody knows how to solve this problem?
