Well, you've really got two options. The first is a hot spare, as was
mentioned previously (by Grygoriy, I belive). The second is pooling
(running the servers simultaneously with both making and receiving
calls). If you're familiar with Heartbeat, the hot spare is probably a
simpler setup. For that matter, it's probably simpler even if you're not
familiar with Heartbeat. Pooling requires additional services--DNS for
SRV, AIS if you want presence shared across the PBXes, and a registrar
that maintains SIP registrations across restarts a little better than
Asterisk.
