With which of the following control components do UCM media resources interact when UCM needs to locate
resources to establish transcoding? (Select the best answer.)

A.
call control

B.
media control

C.
MTP control

D.
MOH control

Explanation:
Cisco Unified Communications Manager (UCM) media resources interact with UCM’s media control component
in order to locate resources to establish transcoding, or to establish a media termination point (MTP). The UCM
media control component is responsible for managing the creation and teardown of media streams for a given
endpoint. The UCM Media Resource Manager is responsible for connecting the media streams that comprise
conferencing features, among others. When troubleshooting media resource problems, such as conference call
failures, it is important to first investigate the UCM media resources configuration. UCM media resources are
available directly from the UCM server on which the services are enabled. In addition, the UCM MediaResource Manager enables UCM to provide those services to other UCM servers in a cluster.
UCM media resources do not interact with UCM’s call control component when UCM needs to locate resources
to establish transcoding. However, UCM media resources do interact with UCM’s call control component when
locating resources to establish a conference call or music on hold (MOH).
UCM media resources do not interact with UCM’s MTP control component when UCM needs to locate
resources to establish transcoding. UCM media resources interact with UCM’s MTP control component in order
to reserve transcoders within a UCM cluster.
UCM media resources do not interact with UCM’s MOH control component when UCM needs to locate
resources to establish transcoding. UCM media resources interact with UCM’s call control component in order
to locate resources to establish an MOH session. Because the MOH control enables UCM to redirect a caller to
an audio server, UCM media resources also interface with the MOH control when establishing such a session.
