Media Resource Group Configuration

Media resource management comprises working with media resource groups and media resource group lists. Media resource management provides a mechanism for managing media resources, so all Cisco Unified CallManagers within a cluster can share them. Media resources provide conferencing, transcoding, media termination, annunciator, and music on hold services.

You can associate a Media Resource Group, a logical grouping of media servers, with a geographical location or with a site as desired. You can also form Media Resource Groups to control the usage of servers or the type of service (unicast or multicast) that is desired.

You can group devices of the following types into a single Media Resource Group:

•Conference Bridge (CFB)

•Media Termination Point (MTP)

•Music On Hold Server (MOH)

•Transcoder (XCODE)

•Annunciator (ANN)

Use the following topics to configure Media Resource Groups:

•Finding a Media Resource Group

•Configuring a Media Resource Group

•Media Resource Group Configuration Settings

•Deleting a Media Resource Group

•Understanding Media Resources, Cisco Unified CallManager System Guide

Finding a Media Resource Group

Because you might have several media resource groups in your network, Cisco Unified CallManager lets you locate specific media resource groups on the basis of specific criteria. Use the following procedure to locate media resource groups.

Deleting a Media Resource Group

Perform the following procedure to delete an existing Media Resource Group.

Before You Begin

You cannot delete a Media Resource Group that is assigned to a Media Resource Group List. To find out which media resource groups lists are using the media resource group, in the Media Resource Group Configuration window, from the Related Links drop-down list box, choose Dependency Records and click Go. If the dependency records are not enabled for the system, the dependency records summary window displays a message. For more information about dependency records, see the "Accessing Dependency Records" section on page A-2. If you try to delete a media resource group that is in use, Cisco Unified CallManager displays an error message. Before deleting a media resource group that is currently in use, you must perform either or both of the following tasks:

•Assign a different media resource group list to any media resource groups that are using the media resource group that you want to delete. See the "Configuring a Media Resource Group List" section on page 61-2.

•Delete the media resource group lists that are using the media resource group that you want to delete. See the "Deleting a Media Resource Group List" section on page 61-4.
