NAP failover to unique PSTN number

[Eric]

Hi all,

I'm studying this failover scenario and wanted to know if anyone already did (or thought to do) it.

Concept:
- NAP to customer's IPBX is active and a range of numbers is routed to it
- NAP is (for whatever reason) down
- When an incoming call from a NAP pointing to the PSTN carrier with a called number belonging to this range occurs, change the called number to another one and route it back again to the PSTN NAP

The final goal is to achieved a failover of a NAP, not to another NAP, but rather to an E1 line to which the customer's IPBX is connected. In this case, as all incoming calls are pointing to a unique number (E1), an attendant will answer those calls.

Help is welcome ! Thanks.

I want to hear about this solution too.
