Packet Capture Duration (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 information on this field, refer to the Cisco
Unified Communications Manager Security Guide.
Media Resource Group List 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 a Media Resource List defines.
Location 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 protocol or
SIP.
To configure a new location, use the System > Location menu
option.
For more details about locations, see the “Location Configuration”
section on page 17-1. For an explanation of location-based CAC
across intercluster trunks, see “Location-Based Call Admission
Control Over Intercluster Trunk” in the Cisco Unified
Communications Manager System Guide.
AAR Group Choose the automated alternate routing (AAR) group for this
device. The AAR group provides the prefix digits that are used to
route calls that are otherwise blocked due to insufficient bandwidth.
An AAR group setting of None specifies that no rerouting of
blocked calls will be attempted.
Interface Information
BRI Protocol Choose the communications protocol for the span.
BRI-NET3
Protocol Side Choose the appropriate protocol side. This setting specifies whether
the gateway connects to a Central Office/Network device or to a
User device.
Note BRI supports only the User side.
