This document describes an issue in the Cisco IP Interactive Voice Response (IVR) CallManager environment where calls are queued and then terminated at 180 seconds and a possible workaround.
Readers of this document should have knowledge of these topics:
Cisco Intelligent Contact Management (ICM)
IP IVR Configuration
The information in this document is based on these software and hardware versions:
Cisco ICM 4.6.2 and later
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

The MIVR and JTAPI logs are generated under the path of C:\Program Files\wfavvid\log on the IP IVR server:
CiscoMIVR01.log - CiscoMIVR10.log and CiscoJtapi01.log - CiscoJtapi10.log
On the IP IVR Server, open the CiscoMIVRxx.log for the time in question to locate the problem. The levels of tracing shown in this example should be turned up on the IP IVR process.
This is an example of a call followed by a cancel message 180 seconds (3 minutes) later.

For IP IVR trace, select AppAdmin > Engine > Trace Configuration and click to select SS_TEL, SS_ICM, and LIB_ICM.
Complete these steps to resolve this problem:
Select Start > Programs > Configuration Manager on an AW to open the Configuration Manager.
Open Configure ICM.Figure 1: Configuration Manager
Select Targets > Network VRU Script > Network VRU Script List.
Click Retrieve. This pulls back the entire Network VRU configuration and the Attributes window opens.Figure 2: Attributes
Note: The Timeout field, which is required, is defined by the number of seconds (the default is 180). This value is the number of seconds that Cisco ICM should wait for a response after the routing client is directed to run the script. If Cisco ICM does not receive a response from the routing client that watches this time, it assumes the VRU script has failed.
Increase this timer to 3600 seconds or higher, based on the business requirements for the location.
Note: There is a registry key on the Peripheral Gateway (PG) under the Open Peripheral Controller (OPC) process called "MaxQueueTimeAllowedForCall". This value has no effect on this problem.
