Fpbx 13/Asterisk 11 with no return inbound audio. This is a ported config from my current FPBX 12 with Asterisk 1.8 (I upgraded 12-to-13). The current NAT config has been correctly working for several years and yet when I compare packet traces from the current (working) PBX with the new one, I see a problem that explains why no RTP can return. All traffic from this box gets nat'ted to a fixed outside address and vice versa on the return of course. The SIP exchanges works fine on the correct address which confirms the NAT. But for some reason the INVITE uses the incorrect address in Message Header->Via: where it shows the external address to be the external default gateway, not the external address specifically assigned to the PBX. I don't even know where it gets that address. I looked carefully through the config - the NAT settings imported correctly. I even searched the asterisk database to see if the incorrect IP was lurking there somewhere but it's not. So Asterisk is obtaining this external address somehow on its own. Where does it get this?
