Which four Cisco Unified CM components can request media resource deallocation? (Choose four)
A. call dependency call control
B. unicast bridge control
C. device manager
D. music on hold control
E. line control
F. matrix control
G. call control
H. trusted relay point
A or G depending on semantics for call control:
The Call Control software component performs call processing, this includes setup and tear down of connections. Call Control interacts with the feature layer in order to provide services like transfer, hold, conference, and so forth. Call Control interfaces with the Media Resource Manager when it needs to locate a resource in order to set up a conference call and/or MOH features.
So for basic call control it appears to not be need resources to deallocate, but for call “dependent” services control it does need to.
The media resource manager interfaces with the following major components:
•Call control
•Media control
•Media termination point control
•Unicast bridge control
•Music on hold control
•Annunciator control
•Trusted relay point
