Sounds like a configuration issue. IIRC linphone allows you to specify the 
external IP and will actually use it. I haven't looked at it in a long time 
though as I started using an outbound proxy, in my case siproxd. It makes the 
firewall configuration much easier, and stops the problems that can occur with 
some configurations of NAT at both ends of the call.
