At present I have two hardware identically freepbx/asterisk boxes. The mysql db on one is slaved to the other and all config files are rsync’d once every 24 hours (we have few configuration changes).
We use Polycom 321/331/550/650 phones, and I notice that these phones can be configured with two SIP servers.
Would the simplest approach to failover be to just configure my primary Asterisk server as the first SIP server and my backup as the second?
Kind Regards, Chris
