[Asterisk-Users] dual IP connections

this is a routing problem, not an asterisk one.
you can do some ip policy based routing , but imho
if you implement this is better to have another
box between the * one and the 2 isp links that do the load
balance, or the switch to the bkp isp if the first one
goes down.
my idea is:

asterisk box(one nic) -> router(3 nics) -> isp1
		                       -> isp2

the on router you can play with ip policy based routing
or simply failover routing.

cya,
Matteo.
