Any pointer or help would be greatly appriciated.

Cheers, Dirk

Are you using -A flag in rttproxy?

So, to bridge to outside from kamailio you'll need to use advertised address with public IP as well as -A flag in rtpproxy (I've been using either the @miconda patched version or 2.0).

Then on inside communications, you'll need to set rtpproxy (override) to use NAT/LAN IP, and use the public IP for the other side.

Something like...

if(dst_ip==ASTERISKIP) { rtpproxy_manage("co","PRIVATEIP"); } else { rtpproxy_manage("co"); }
