DescriptionField
This list provides a prioritized grouping of media resource groups. An
application chooses the required media resource, such as a Music On
Hold server, from among the available media resources according to
the priority order that is defined in a Media Resource Group List.

Configure this field only when you need to troubleshoot encrypted
signaling information for the Cisco IOS MGCP gateway. Configuring
packet capturing may cause call-processing interruptions. For more
information on this field, refer to the Cisco Unified Communications
Manager Security Guide.
Packet Capture Mode (for Cisco IOS
MGCP gateways only)
Configure this field only when you need to troubleshoot encrypted
signaling information for the Cisco IOS MGCP gateway. Configuring
packet capturing may cause call-processing interruptions. For more

From the drop-down list box, choose the appropriate calling search
space. A calling search space comprises a collection of route partitions
that are searched to determine how a collected (originating) number
should be routed.
Calling Search Space
Choose the appropriate calling search space for the device to use when
it performs automated alternate routing (AAR). The AAR calling
search space specifies the collection of route partitions that are
searched to determine how to route a collected (originating) number
that is otherwise blocked due to insufficient bandwidth.
AAR Calling Search Space
Use locations to implement call admission control (CAC) in a
centralized call-processing system. CAC enables you to regulate audio
quality and video availability by limiting the amount of bandwidth
that is available for audio and video calls over links between locations.
The location specifies the total bandwidth that is available for calls to
and from this location.
From the drop-down list box, choose the appropriate location for this
device.
A location setting of Hub_None means that the locations feature does
not keep track of the bandwidth that this device consumes. A location
setting of Phantom specifies a location that enables successful CAC
across intercluster trunks that use H.323 or SIP protocol.
To configure a new location, use the System > Location menu option.
For more details about locations, see the Cisco Unified
Communications Manager Administration Guide. For an explanation
of location-based CAC across intercluster trunks, see the Cisco Unified
Communications Manager System Guide.
