If your phones are setup to connect to the asterisk box by name, then a smart DNS server can just point phones to the backup box after failure. However, since asterisk running on the backup box doesn't know about the phones, this is only half the solution ________________________________ From: Mohamed A.

Of course this solution can be broken by phones that cache DNS answers, and the phone may require a reboot to actually force it to go and contact the smart DNS server for a new ip address. -Chris Michael Stahl wrote:> If your phones are setup to connect to the asterisk box by name, then > a smart DNS server can just point phones to the backup box after > failure.

Then you need to cluster your DB servers so they aren't a point of failure.
