Thanks Brian. Sorry, should have done a full sip trace before, but here is one now:<a href="http://pastebin.freeswitch.org/12632"></a><br><br>Calling an IVR dialplan:<br><a href="http://pastebin.freeswitch.org/12634">http://pastebin.freeswitch.org/12634</a><br>

<br>Calling from one extn to another.<br><a href="http://pastebin.freeswitch.org/12633">http://pastebin.freeswitch.org/12633</a><br>(With this one, the source/calling softphone gets a message on it saying put on hold by the other user - not sure if that helps.)<br>

<br>For what it&#39;s worth, at a couple of points when I was running the trace I was pressing keys to generate dtmf, and nothing changed on the screen - no activity at all.<br><br>Also, I&#39;ve been able to remote desktop into a computer on another network, and install x-lite and it can connect to our internal server and works fine, but it can&#39;t do dtmf on the EC2 server either (so it&#39;s definitely a problem on the server end somehow, not my local network&#39;s NAT.)<br>
