Hello, My host just had a faulty power supply and therefore, my Asterisk server was down for 7 hours. It was a Sunday so no one was making calls, however if it happened during the week, I'd have problems. I was trying to find a whitepaper or advice on how to set up two Asterisk servers to provide some redundancy. I've been googling "asterisk redundancy" but all I've found is questions, and no real answers. I've seen OpenSer mentioned but how does that help if extensions are dialling each other and they are registered on different servers? Or should I simply set up a standby server and switch to it if there are any problems? My platform is purely IP/SIP based. No ISDN/Analog connections. Does anyone have some advice or links on redundancy? Many thanks Dan -------------- next part -------------- An HTML attachment was scrubbed...

Was it the power supply in the server or a phase? Even an HP DL360 has redundant power supplies, you just yank out the bad one and put a new one in, no downtime. If it is power in the building, then maybe you should move your system to a better "Host" that has different phases and plug your server into both, via dual power supply, like the DL360. All of my servers at Equinix are plugged into two different "Power Sources". You can also use HA Linux (Heartbeat) in case a box dies. Thanks, Steve T
I agree that better hardware is needed. I'm looking into buying my own servers and getting a rack in a data centre. I'll impliment a redundancy solution at the same time. Thanks for the links.
