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");
	}
