MRGLs are an ordered list of MRGs. The MRGs contain the media resources in the Cisco CallManager cluster. By assigning a MRGL to a device, you grant access to whatever resources are contained in the MRGs the MRGL contains.

2.

B and C

The Media Resource Manager (MRM) manages all resources in the CallManager cluster. The software-based resources are all grouped under the Voice Media Streaming Application, which is activated in a Cisco CallManager server. Transcoding is one example of a hardware-based resource.

   
3.

A

Hardware-based conference bridge resources are identified to the CallManager by their MAC address. Most of the configuration for these resources takes place on the resource itself.

4.

B

The Voice Media Streaming Application is a service that runs on the Cisco CallManager servers. It allows the CallManager server to participate in all media resource functionality, including conferencing, media termination point, music on hold, and annunciator.

5.

B

Network hold MoH is played anytime a person is placed on hold because of a network-related function. These functions include conference calls, transfers, and Call Park. User hold MoH sources are only played when the user literally presses the hold button on their IP Phone.

6.

A

The Cisco CallManager server creates individual unicast streams for IP Phone users. Multicast support must be configured on a per-server and per-audio source basis.

7.

B

When a MRGL is assigned at both the device pool and IP Phone level, the MRGL on the IP Phone takes precedence. The MGM will use the MTP resource listed first in the first MRG of the IP Phone MRGL.

8.

B

By default, the media resources are assigned to the default MRG, which cannot be modified or deleted. The MRM will use a round-robin load-balancing system for these resources.

9.

E

Because of the amount of processor resources consumed by session transcoding, this function is limited to hardware-based digital signal processor (DSP) resources.

10.

C

The fixed audio source is always assigned audio source ID 51. This audio source ID must be linked to a fixed sound device in the CallManager server before it becomes active.
