Cisco Cisco Customer Voice Portal 8.0(1)

Note: You can replace "my-survivability-service" with any name you choose.

Then associate the my-survivability-service that you just created as a parameter on the
CVPSelfService.tcl service associated with the incoming pots dial-peer. Note that the text "param
survive" must be entered exactly as shown, but the my-survivability-service can be renamed to
the service name of your choice. For example:

dial-peer voice XXXX pots

service my-CVP-service

incoming called-number NNNNN

service my-CVP-service flash:CVPSelfService.tcl

param CVPPrimaryVXMLServer my-VXML-server-IP

param CVPBackupVXMLServer my-backup-VXML-server-IP

param CVPSelfService-app my-VXML-server-app

param keepalive my-CVP-service

param survive my-survivability-service

service my-survivability-service flash:survivability.tcl

Optionally, start a background keepalive service to the VXML Server. For example, for a service
name of "my-standalone-service":

service my-standalone-service

param keepalive my-standalone-service

Note: This service prevents the caller from hearing a period of silence at the start of each call
if the VXML Server is down, as the gateway will know the current status of the VXML Server.

On the gateway, do a "call appl voice load my-survivability-service" and "call appl voice load
handoff."

Do the following:

On a Unified CVP Comprehensive call flow model:

•

Create a Unified CVP pots dial-peer on the gateway, placing the Unified CVP called number
on an incoming-called-number parameter.

•

Assign the my-survivability-service service to this dial-peer.

On a Unified CVP Standalone call flow model, no special survivability dial-peer needs to be
created. However, the parameter "param survive my-survivability-service" must be included
on the CVPSelfService.tcl service. This parameter indicates which service to run in the event
of a system failure. In this way, different survivability services can be invoked depending on
the incoming pots dial-peer invoked.

How to Configure the Gateway for Call Survivability

You can configure the following parameters on the gateway for call survivability:
