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

[Darryl Dunkin]

What does the call setup look like on this? You can either debug sip in
the console or 'ngrep -s 1500 -T -W byline host 75.36.34.98'

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

 

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?
