I think heartbeat will suit you fine. The advantage of heartbeat in your
case that asterisk is not running on spare, so no trunks get confused by
double registering. Heartbeat permit to share one vertual address and pass
it from one server to another. Also i would recommend to use spare ethernet
interface/com port for "beats" So that 2 * get directly connected. Second
thing which is important, use watchdog to monitor the asterisk pid, if no
process > reboot. Of course you get the problem with voicemail, but you need
to just syncronize folders. Also forgot to mention that heartbeat has one
interesting feature as "autofallback= on|off" If set to on when primary
server come back he will retake his "resources" (*) if set to no, when he is
ready he will wait till the second server fail. I prefer to use with = no,
but its just me. Also do not forget to reduce the time of registering to 60
sek or so. I hope i helped.
