Hello,<br>
<br>
is Asterisk supposed to forward the video stream as well? When you
mean Asrerisk has only local address, means its address is not
routable from the sip clients, right? If yes, have you set rtpproxy
in bridged mode?<br>
<br>
A ngrep trace of the sip signaling for a call which does not work
would be useful to provide more details about what could be wrong
there.<br>
<br>
Cheers,<br>
Daniel<br>

<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>
