[Asterisk-Users] IAX Trunking Weirdness

[Rod Bacon]

For those who are interested, the problem is being caused by IAX using the wrong 
  outside IP address as it's source address.

(Multi-homed firewall with numerous virtual interfaces). The workaround was to 
add additional definitiions to the other servers, so the connection will be 
trunked from the originating (incorrect) address.

Apparently there is a patch against CVS HEAD which allows the definition of the 
source address on a per-peer basis.
