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?
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???

BlackBox in Australia claimed they could build me a device which would route BRI and PRI lines via mechanical relays, and could be driven by a very simple heartbeat failover circuit. But such a device wouldn't be 'A-Tick' certified which means it would be illegal to connect it to the phone network in Australia. I've since been thinking that the best way to accomplish this would actually be a TDMoE PRI device, which would take the PRI signalling in one side and send TDMoE out the other. Software heartbeat and failover would decide which Asterisk box talked to it. You then have the TDMoE PRI device as the single point of failure, but I believe such a device has a much longer MTBF than a server, and in any case if you came up with a relay box (or ISDNGuard for that matter) you would still have that as the single point of failure anyway. Can anyone recommend a PRI-to-TDMoE device? Does such a thing exist? James
