[Asterisk-Users] Failover Device?

[Carlos Alperin]

Do you need failover on wich side? PRI or Asterisk? Both?

Straight to the last option:

PRI: the best if you have more than one PRI is to do hunt on the provider
side, so when one is full or down, all calls are going to be directed to the
second one.

Asterisk: Do redundancy, so you need to have a second Asterisk box ready for
failover, taken all the traffic of the first one in such case. You can do
Hearthbeat, or DNS handling for this. I never try to run asterisk in a
Cluster, that can be a third option.

Any experience on that direction???

Regards,

Carlos

First,
Something seems to be wrong with the list.  I'm not the only person
who has expressed seeing their messages either arrive late, or not at
all.

With that out of the way..

Is anyone aware of any type of failover device for PRI on asterisk? 
I've found the ISDNGuard, however it is currently not made in the
U.S., nor does it run on U.S. power.

Is anyone aware of a device that will detect (heartbeat?) if Asterisk
is running, and if not, failover to a backup server?
