| The current solution I have uses UltraMonkey ( [http://www.ultramonkey.org] ) for load-balancing and failover and it works like a champ. There are obviously a lot of details there, and I'd be happy to detail them if people are interested. There is also a site that has two clusters with uniform reachability for all phones and PRIs. None of this requires a lot of dialplan tuning on a day-to-day basis. | | | | !!See also | | +* ((Asterisk High Availability Design)): High Availability Design | | * [http://lists.digium.com/mailman/listinfo/asterisk-ha-clustering|Mailing list] for Asterisk High-Availability | | * [http://www.asterisk.org/node/48321|Load balancing with DUNDi] | | * ((Asterisk administration)) |
