Voice Gateway Availability

Unanswered Question
May 28th, 2007

Is there a way to design and configure voice gateway acting like the concept of hot standby routing protocol (HSRP) ? If one of the voice gateway goes down, the "standby voice gateway" will replace it and use the same line/voiceport to PSTN.

I have this problem too.

Not that I know of, but then generally I would consider the NTE or PSTN line to be more of a point of failure than a Cisco router.

Therefore if resilience is absolutely necessary I would recommend 2xPSTN connections and two gateways to be sure. Otherwise a single router with dual power etc etc should suffice.

Hope that helps.

A ha, I got your point. Thanks a lot, Doug!

Does Cisco recommend design like this ? how about SRND ?
