<p>Hi Nick,<br>
So you've forwarded the 5060 port to opensips server, cool. Did you forget to mention about the RTP ports forwarded to server ? <br>
Start RTPproxy with param -m and -M to assign range of RTP ports to use. Then forward that UDP port range to opensips server too.<br>
Then see what happens with audio.<br>
Also what is your total voip diagram with their network addresses. </p>
<p>Thanks,<br>
Sammy<br>
