<div>Hi,</div>
<div> </div>
<div>I have a strange problem using FreeSwitch on an Amazon EC2 instance and was
wondering if anyone out there could help me.</div>
<div> </div>
<div>The problem seems to be that I can register an extension from a remote
network in say France, phone works ok but when passing calls to it (from sip
peer through JavaScript to user extension) I get one way audio, the caller can
hear me on the softphone but I can’t hear them – like the reverse audio path
can’t be established.</div>
<div> </div>
<div>That would be ok and fixable if the issue was consistent but on another
phone registered from within the UK, it all works fine and I get a good 2 way
conversation.</div>
<div> </div>
<div>If I dial from one softphone in France directly to the other in the UK,
that works too.</div>
<div> </div>
<div>I followed the wiki’s guide to installing on Amazon and have everything
right, otherwise I doubt it would work at all.</div>
<div><br>Is anyone able to help me or have experience of this type of issue?
Maybe it’s a local router issue to the phone in France but I didn’t need to do
anything special to the one in the UK to work, so not sure it could be that
either.</div>
<div> </div>
<div>Kind Regards,</div><span class="HOEnZb"><font color="#888888">
