Troubleshooting
Issue 1: ICM Fails to Find the VRU Label
No Customer Defined on the Dialed Number
No "Network VRU" Defined on Customer
No VRU Label for Routing Client
PG has no "Network VRU" Configured
Issue 2: CVP has no Route for VRU Label
Issue 3: VXML Gateway Fails to Invoke VRU TCL Script
Not Matching Correct Dial−Peer
No Application/Service Configured on Dial−peer
Issue 4: VXML Gateway not Able to Send HTTP Request to CVP
Header Passing is Not Configured
Issue 5: CVP Splits VRU Label and Correlation ID Wrong
Issue 6: ICM/CVP sends wrong URL
Media URL is Incomplete
Media URL for VXML Server is Incorrect
Issue 7: SigDigit
CVP has no Route for the VRU Label after Prepending SigDigit
Issue 8: VXML Gateway Application is not Configured for SigDigit
Issue 9: CallManager gets the Wrong VRU Label to Transfer
Issue 10: CallManager does not Prepend SigDigit to the VRU Label

Introduction
This document describes the "Send to VRU" and "Run Ext Script" failures. The approach taken is called
Predictive Troubleshooting. With predictive troubleshooting, you will be made aware of the problem based on
the logs, the related behavior, and how best to address it.

In Customer Voice Portal (CVP) deployments, call failures at the "Send to VRU" or "Run Ext Script" node
are very common. Even though it is just a single node in Intelligent Contact Management (ICM), there are lots
of signaling events that need to occur on CVP, the Voice XML (VXML) gateway and/or the VXML server.
