[Freeswitch-users] SIP, NAT and Amazon EC2

[Damon Brown]

I have verified all of my steps based on the wiki.  When I make an 
outbound call (or any call that would affect NAT), I hear the ring for a 
second than it disappears.  The console shows:

I used the Quick and Dirty Install .... I believe I'm close and just 
missing something.  Any other thoughts?

Thanks all for your help
