you cannot get rtpproxy listening on the ec2 public ip, which does
not exist on the network interface.<br>
<br>
You will have to use a patched rtpproxy, that adds advertising
address support. I had such patch for my own usage, now I polished
it a bit and push it to github:<br>

<br>
Give it a try, hope I haven't broken it with last polishing, if does
not work let me know.<br>
<br>
You should be able to apply it to latest rtpproxy stable release.
Once you compile and install, then run rtpproxy with:<br>
<br>
<br>
rtpproxy -F -l localip -A publicip -s <a rel="nofollow" class="yiv7724724747moz-txt-link-freetext" href="">udp:localhost:7722</a><br>
