it's a small office with 40 - 50 sip extensions. Most of the users have both a
hard phone and a soft phone which is why there are so many sip extensions. There
are only about 15 users and a few other misc extensions for phones in public
areas. PRI access is via IAX to another asterisk server that contains all
the PRI hardware. There is a 4port Sangoma Analog card in the PBX for a few
local lines. I am planning on putting a second Sangoma card in the other server
for redundancy, but the physical analog connection doesn't have to be
automatically switched over on failure.</span></font></div>

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.<br>
