Hello,<br>
<br>
the sdp does not show that rtpproxy was engaged. Check your config,
you can use debugger module with cfgtrace on to see what actions are
executed.<br>
<br>
Also, probably you have to advertise the public ip address of your
ec2 instance -- see second parameter for rtpproxy module functions.<br>
<br>
Cheers,<br>
Daniel<br>
