Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) Administrator's Guide

You can also define your own expanded call variables in the 
Configure ICME tool in the Unified ICME system. The Unified 
CCX Engine registers the user-defined expanded call variables with 
Unified ICME after it loads the VRU scripts that use these variables. The 
variables remain registered until the Unified ICME session is reopened 
(either by request from the VRU PG or when the Unified CCX Engine is 
restarted). The variables remain registered even if you delete the script 
that uses them.
