asterisk users - Jan 2005 - Server auto Fallback

I am looking at setting up redundant servers for my client and I know the first
step in creating an auto fall back would be to have the FQDN set up in such a
way that it points to both of the server IP addresses, but, how can I make it so
that the phones will (with minimal delay) authenticate with tha backup server in
the event of a primary server failure?

Thanks,

Dan

Currently I have a toll free line set up on my PBX at home, and it is working
great, BUT, when an inbound call comes in, the CID is reporting toll free call.
Does anyone know how I can get around this problem?

Thanks,

Dan

Dan,

The senario you are discribing is very much like auto
failover nat firewalls.
That's why the first thing that comes to mind is OpenBSD's
CARP: http://www.openbsd.org/faq/faq6.html#CARP
I have * running on OpenBSD 3.6 without any problem.
