[asterisk-users] Binding asterisk to two static IPs

[Tarek Sawah]

i had a similar challenge having Asterisk listen to multiple ports.. "some of my agents located in countries where SIP is blocked" 
the only effective way is to use IPTABLES i believe your problem can be solved with the same method.
