you should grab a ngrep trace on server to see what happens in the

<div>The call reaches Asterisk, but not vice-versa. No media
is being transferred.<br>

<div>Rtpengine flags I use:<br>
</div>
<div>For SIP: rtpengine_manage("trust-adress replace-origin
replace-session-connection RTP/AVP");<br>
</div>
<div>For WS: rtpengine_manage("trust-address replace-origin
replace-session-connection ICE=force RTP/AVP");<br>
<br>
</div>
<div>Do you have any ideas how ti fix that? I also make
REGFWD's to Asterisk<br>
