[cisco-voip] CVP Standalone Survivability GW Config

[Alan Diaz]

Hello All - Any help is much appreciated.


I'm having issue with getting the survivability.tcl script to trigger and
transfer to a number or hand off to a auto-attendant. I have been following
the CVP 8.0 Config Guide but it is very confusing and believe it is missing
info.

The environment is a CVP standalone solution with one ingress/vxml gateway.
Currently I am testing this functionality without the CVP servers in the
picture because of my location. I'm thinking this is not an issue as this
will simulate a WAN failure/CVP Server application errors. Am I wrong?

Incoming dial-peer 2 should trigger the survivability.tcl script because
there is no connection to the CVP VXML server that would (in normal
operation) trigger the ADstore service, correct?

If so, the ADsurvive service should then transfer to 1111. I've also tried
to configure this service with the "param aa-name aa" statement to handoff
to the auto-attendant, but failed. Using the handoff to a auto-attendant
method is really what I would like in my solution.

GW config: I have all the required tcl scripts/vxml files in flash.
