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 that they can be shared by all Cisco CallManagers within a cluster. Media resources provide conferencing, transcoding, media termination, 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) 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)
