Conference Bridge Configuration


In Cisco Unified Communications Manager Administration, use the Media Resources > Conference Bridge menu path to configure conference bridges.

Tips About Configuring Conference Bridges

Make sure that the following prerequisites are met before you proceed with configuration of a conference bridge:

Configure the device pools. See the "Tips About Deleting Device Pools" section on page 8-2.


Note Software conference bridges automatically get created when the Cisco Unified Communications Manager server gets created. You cannot add software conference bridges to Cisco Unified Communications Manager Administration. See the "Software Conference Bridge Configuration Settings" section.


For software conference bridges, activate the Cisco IP Voice Media Streaming Application service. See the Cisco Unified Serviceability Administration Guide.

Tips About Deleting Conference Bridges

Keep in mind that you cannot delete Cisco Unified Communications Manager Conference Bridge Software. See the "Conference Bridge Configuration" section.

Cisco Unified Communications Manager allows you to delete devices that may be associated with components such as media resource groups. To find out what dependencies the conference device may have, choose the Dependency Records link from the drop-down list box and click Go from the Conference Bridge Configuration window. If the dependency records are not enabled for the system, the dependency records summary window displays a message. For more information about dependency records, see the "Accessing Dependency Records" section on page A-2.

Using the GUI

For instructions on how to use the Cisco Unified Communications Manager Administration Graphical User Interface (GUI) to find, delete, configure, or copy records, see the "Navigating the Cisco Unified Communications Manager Administration Application" section on page 1-13 and its subsections, which explain how to use the GUI and detail the functions of the buttons and icons.

Software Conference Bridge Configuration Settings

Conference Bridge for Cisco Unified Communications Manager, a software or hardware application, allows both ad hoc and meet-me voice conferencing. Each conference bridge can host several simultaneous, multiparty conferences.

Be aware that both hardware and software conference bridges can be active at the same time. Software and hardware conference devices differ in the number of streams and the types of codec that they support.

You cannot add software conference bridges to Cisco Unified Communications Manager by using Conference Bridge Configuration. Software conference bridges automatically get added when a Cisco Unified Communications Manager server gets added (see the "Server Configuration Settings" section on page 2-1 for more information). After a Cisco Unified Communications Manager server gets added, the software conference bridge gets displayed in the Find/List Conference Bridges window (by default, the first software conference bridge gets configured during Cisco Unified Communications Manager installation) when you perform a search. You can update software conference bridges, but you cannot delete them.

See the "Conference Bridges" chapter of the Cisco Unified Communications Manager System Guide for more information about conference bridges.

Table 51-1 describes the software conference bridge configuration settings. For related procedures, see the "Related Topics" section.

Table 51-1 Software Conference Bridge Configuration Settings 

Field
Description

Conference Bridge Type

This field automatically displays Cisco Conference Bridge Software.

Host Server

This field automatically displays the Cisco Unified Communications Manager server for this software conference bridge.

Conference Bridge Name

This field automatically displays the software conference bridge name. The format of the name specifies CFB_ followed by a digit that represents the value of the software conference bridge; for example, CFB_3 represents the third conference bridge in the Cisco Unified Communications Manager system.

Description

This field automatically displays a description, but the administrator can update this field.

Device Pool

Choose a device pool that has the highest priority within the Cisco Unified Communications Manager group that you are using or choose Default.

Common Device Configuration

Choose the common device configuration to assign to the conference bridge. The common device configuration includes attributes, such as MOH audio source, that support features and services for phone users.

Device configurations that are configured in the Common Device Configuration window display in the drop-down list. See Common Device Configuration for more information.

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 conference bridge.

A location setting of Hub_None means that the locations feature does not keep track of the bandwidth that this conference bridge 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 15-1. 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.

Use Trusted Relay Point

From the drop-down list box, enable or disable whether Cisco Unified CM inserts a trusted relay point (TRP) device with this media endpoint. Choose one of the following values:

Default—If you choose this value, the device uses the Use Trusted Relay Point setting from the common device configuration with which this device associates.

Off—Choose this value to disable the use of a TRP with this device. This setting overrides the Use Trusted Relay Point setting in the common device configuration with which this device associates.

On—Choose this value to enable the use of a TRP with this device. This setting overrides the Use Trusted Relay Point setting in the common device configuration with which this device associates.

A Trusted Relay Point (TRP) device designates an MTP or transcoder device that is labeled as Trusted Relay Point.

Cisco Unified CM places the TRP closest to the associated endpoint device if more than one resource is needed for the endpoint (for example, a transcoder or RSVPAgent).

If both TRP and MTP are required for the endpoint, TRP gets used as the required MTP. See "TRP Insertion in Cisco Unified Communications Manager" in the Cisco Unified Communications Manager System Guide for details of call behavior.

If both TRP and RSVPAgent are needed for the endpoint, Cisco Unified CM first tries to find an RSVPAgent that can also be used as a TRP.

If both TRP and transcoder are needed for the endpoint, Cisco Unified CM first tries to find a transcoder that is also designated as a TRP.

See "Trusted Relay Point" and its subtopics in the "Media Resource Management" chapter of the Cisco Unified Communications Manager System Guide for a complete discussion of network virtualization and trusted relay points.

Hardware Conference Bridge Configuration Settings

Conference Bridge for Cisco Unified Communications Manager, a software or hardware application, allows both ad hoc and meet-me voice conferencing. Each conference bridge can host several simultaneous, multiparty conferences.

Be aware that both hardware and software conference bridges can be active at the same time. Software and hardware conference devices differ in the number of streams and the types of codec that they support.


Note The hardware model type for Conference Bridge contains a specific Media Access Control (MAC) address and device pool information.
