</div>Not enough info to suggest a problem cause.<br>
You should inspect the SDP in the INVITE received by the callee and<br>
the 200 OK received by the caller in all the cases, and verify if they<br>
make sense (if you are using RtpProxy for these calls you should see<br>
there the IP of RtpProxy, if not you get unidirectiaonal audio and<br>
so).<br>
<br>
Also, being behind symmetric NAT doesn't matter here since you are<br>
using RtpProxy.<br>
<br>
Question: Are all your phones in the same network? is the proxy and<br>
RtpProxy behind NAT (I hope not)?</blockquote></div><div><br>the extension 123 and 202 is in the same netwotk behind a symmetric nat and my server this in another network and he has an ip public .<br><br>the problem is that when those extensions call there is not you bidirectional audio, alone in one of them<br>
<br><br>I see in the sdp of the message that the proxy puts me an a=nortpproxy:yes and not you because!<br><br>ideas as solving this problem? <br><div class="Ih2E3d"><br><pre>v=0 <br>o=202 8000 8000 IN IP4 192.168.10.40 <br>
