[Asterisk-Users] SIP and * with dual ethernet cards

[Flynn]

hi all,

i've got a proposed setup that i was wondering if you guys could comment
on.

the client wants * and a couple of SIP phones to be on a separate network
than the rest of the office, so that in case their primary network
crashes for some reason the PBX won't be affected.

one other factor: the client may at some later point set up SIP UAs
sitting on the primary network that will connect to the * box.

which of these would be the best way to do it:

1. two NICS on * box
2. * box behind switch/router that connects the two networks
3. something else?

if #1 is the way to go, how would I configure sip.conf (and other conf
files) to accommodate the second NIC?

thanks in advance.
