<div>My whole configuration is:</div><div>[Sip clients] < = > Kamailio 3.2 <=> Asterisk servers (behind Kamailio)</div><div>Asterisk servers have only local IP addresses, and I use t_relay instead of forward.</div>
<div>Kamailio runs on same server as rtpproxy.</div><div><br></div><div>Now I played lot of combinations and I have next results:</div><div>1. Clients are in same net with Kamailio server (and Asterisk server). Client call Kamailio, Kamailio t_relay to Asterisk, Asterisk dial back to Kamailio, and Kamailio dial Client. rtpproxy is working. Video and audio are fine...</div>
<div>2. Same as above, but clients are behind NAT. Sound is perfect, no video.</div><div>3. Same as in point 1, but no rtpproxy, and no Asterisk servers. Sound and video are perfect. With rtpproxy - no voice, no video.</div>
<div><br></div><div>I would like to find solution for point 2. Sound and video are on different rports (seen in wireshark). As I understand, my error is either in wrong forwarding of ACK (I do t_relay to Asterisk in case from and to addresses are same), or may be I have to find correct FLAGS for rtpproxy_manage(), or even replace it and place with rtpproxy_offer (answer etc).</div>
