This document explains the recommended solutions when the Music On Hold (MoH) unregisters and re-registers with the Cisco Unified Communications Manager (CallMananger).
Cisco recommends that you have knowledge of Cisco Unified Communications Manager (CallManager).
The information in this document is based on Cisco Unified Communications Manager (CallManager) 4.x/5.x/6.x/7.x.
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 MoH server unregisters and re-registers intermittently with Cisco Unified Communications Manager, and the kDeviceMgrRegisterWithCallManagerError: Connection error with Cisco CallManager error message appears in the event log:
Event Type: Error Event Source: Cisco IP Voice Media Streaming App Event Category: None Event ID: 3 Date: 8/9/2007 Time: 8:19:10 AM User: N/A Computer: Cisco-123450B4BDC Description: Error: kDeviceMgrRegisterWithCallManagerError - Connection error with Cisco CallManager. Trace Name: [CFB][22.214.171.124] App ID: Cisco IP Voice Media Streaming App Cluster ID: Cisco-123AF0B4BDC-Cluster Node ID: 126.96.36.199 Explanation: Device manager registered with the specified Cisco CallManager and got a socket error or disconnect. Recommended Action: No action is required; device recovery will handle this.
This error message is most likely a result of a problem with keepalives between the MoH server and the Cisco Unified Communications Mananger.
In order to overcome this issue, complete these steps:
Reboot the Voice Media Streaming Application. Stop and start the IP Voice Media Streaming Application in the Control Center.
Refer to Control Center for more information on how to start and stop various Cisco CallManager services.
Reset the MoH server.
After you upgrade from Cisco CallManager 4.1(3) to Cisco Unified Communications Manager 6.1(2), the MOH server is not registered with the Cisco Unified Communications Manager.
This isssue can occur when the Run Flag parameter under the MoH Server Configuration page is set as No. Set the Run Flag to No on the MoH server in order to disable MoH.
In order to resolve this issue, go to the Cisco Unified CM Administration page and choose Media Resources > Music on Hold Server and set the Run Flag to Yes.
