Hello,<br>
<br>
what are you using for rtp relay? Sending here the sip trace of such
call (e.g., ngrep) would help to spot if the signaling is updated
correctly for nat traversal.<br>
<br>
Cheers,<br>
Daniel<br>

hi,
<div><br>
</div>
<div>I was wondering if in clients in a nat environment need to
be in the dmz or need to have ports forwarded for kamailio to
be used to connect the clients? I have setup kamailio with
the nat settings but am still only getting one way audio.
chances are it has not been setup correctly but just
checking.</div>
<div><br>
</div>
<div>If i try to connect the two clients from the same network i
can get zrtp and 2 way communication working correctly. if
one of the clients is on a different network the call
initiates and answers but zrtp and 2way audio does not work.</div>
<div><br>
</div>
<div>kamailio 3.3 running on ec2</div>
