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

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.


Note During your work in a browser session, Cisco Unified CallManager Administration retains your media resource group search preferences. If you navigate to other menu items and return to this menu item, Cisco Unified CallManager Administration retains your media resource group search preferences until you modify your search or close the browser.


Procedure


Step 1 Choose Service > Media Resource > Media Resource Group.

The Find and List Media Resource Group window displays. Use the two drop-down list boxes to search for a media resource group.

Step 2 From the first Find Media Resource Groups where drop-down list box, choose one of the following criteria:

Name

Description


Note The criterion that you choose in this drop-down list box specifies how the list of media resource groups that your search generates will be sorted. For example, if you choose Description, the Description column will display as the left column of the results list.


From the second Find Media Resource Groups where drop-down list box, choose one of the following criteria:

begins with

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 "Updating a Media Resource Group List" section.

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.
