Hi, I am doing some performance tests and I cannot force SIP INVITEs to use mediaproxy within LAN, without any NAT. I'm using engage_media_proxy or rtpproxy_manage but phones are still exchanging voice data between them, not through the proxy. Is there some trick how to forcibly tell kamailio to use media/rtp proxy ? Maybe kamailio finds out that there is no nat and therefore will not use any nat traversal mechanism. Mino
