[asterisk-users] Call not going through and failing because "never answered"

[Andy Beak]

Ah genius :)  I had tried tcpdump but kept getting a "permission denied" 
error.  When you suggested it I remembered to set AppArmor to complain 
and so now I have a dump of my traffic.  Thanks!  Wireshark is 
illuminating, I think this is a routing error.
