With which of the following control components do UCM media resources interact when UCM needs to locate
resources to establish a conference call?
A.
call control
B.
media control
C.
MTP control
D.
MOH control
Explanation:
Cisco Unified Communications Manager (UCM) media resources interact with UCM’s call control component
when UCM needs to locate resources to establish a conference call. 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 Media Resource Manager enables UCM to provide those
services to other UCM servers in a cluster.
UCM media resources do not interact with UCM’s media control component when UCM needs to locate
resources to establish a conference call. UCM media resources interact with UCM’s media control componentin order to locate resources to establish a media termination point (MTP) or to transcode compression types.
The UCM media control component is responsible for managing the creation and teardown of media streams
for a given endpoint.
UCM media resources do not interact with UCM’s MTP control component when UCM needs to locate
resources to establish a conference call. 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 music on hold (MOH) control component when UCM needs
to locate resources to establish a conference call. 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.Cisco: Media Resource Management: Understanding Media Resources
