asterisk users - Dec 2004 - SIP and * with dual ethernet cards

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.

First of all there's a third option, and that's keeping the phones on a
separate VLAN then the one the PC's are on, and having asterisk reside
on both VLANs.

The problem with a and b regards your intention to have those sip phones
call sip phones that are outside your office (a branch office or a
telecommuter or something along these lines).
If you intend to do so that a and b a re still possible but a lot more
complicated.

As for sip.conf, other then telling * what ip address to listen on (and
I can't remember where that's done, but I believe the default is to
listen on all ip addresses) I don't think there's anything else to
change.
