[Asterisk-Users] Calls connected, but no audio

[Miles Scruggs]

Using sip connections some peers are not able to transmit or recieve 
audio.  All peers are setup the same aside from the NAT settings.  The 
call will go through, called device will ring, but when it answers there 
is no audio connection.  From the callee, they will not here the rings, 
only silence when they dial the phone.

The kicker is that sometimes it will work, and other times it will not.
