[asterisk-users] RTP Packets Going To Wrong IP Address

[Nicholas Blasgen]

I have a user behind a firewall who's had no issues in the past connecting
though his firewall.  He's registered just fine.  But when he places a call,
a large number of them have no audio on either side of the connection.  No
one can hear him, he can't hear anyone as well.  After a lot of poking
around (and changing many settings) I noticed that Asterisk is communicating
the RTP packets to an internal IP address.  My server has no internal IP
address, only an external address, so it's not like we're trying to route
this anywhere else.

As can be seen below, I've already identified the host as being behind a
firewall and therefor to not trust packets from it.  Anyone have a
suggestion?
