[Asterisk-Users] Server auto Fallback

[joosfamily at speakeasy.net]

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
