[asterisk-users] "Simple" failover configuration

[Chris Nighswonger]

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
