[asterisk-users] Asterisk Redundancy

[Dan Journo]

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
