<p class=MsoNormal>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.<o:p></o:p></p>

<div>
<p class=MsoNormal>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?<o:p></o:p></p>
