Conference Bridge


Conference Bridge for Cisco CallManager Release 3.0 is a software application designed to allow both Ad-Hoc and Meet-Me voice conferencing. The conferencing bridge is capable of hosting several simultaneous, multi-party conferences.


Note The hardware model type for Conference Bridge contains a specific Media Access Control (MAC) address and device pool information. A MAC address is a standardized data link layer address that is required for every port or device that connects to a LAN.


The Cisco CallManager Release 3.0 Conference Bridge administration configuration provides you with the following:

For Conference Bridge configuration:

A list of configured Conference Bridge devices

Ability to insert, update, and delete devices

Ability to confirm all deletions

Ability to modify device parameters

Ability to select the software model type

Ability to input a device name

Ability to select Multicast or Unicast conference type

Ability to select a configured server in the system

Ability to select a configured device pool

Ability to input any other necessary parameters for the software device

For Device Pool configuration:

A list of configured device pools

Ability to select a device pool and view all the Cisco CallManagers associated with the device pool

Ability to select a configured Cisco CallManager and modify the conference-related parameters

Ability to disallow any deletion of device pools, Cisco CallManagers, or parameters

For Meet-Me Number/Pattern configuration:

A list of configured Meet-Me numbers/patterns

Ability to insert and delete Meet-Me numbers/patterns

Ability to confirm all deletions

Ability to select a configured Meet-Me number/pattern and modify its parameters

Ability to select the conference type, Multicast or Unicast

Ability to select the route partition

Understanding Conference Devices

For conferencing, you must determine the total number of concurrent users (or audio streams) required at any given time. Then you create and configure a device to support the calculated number of streams. These audio streams can be used for one large conference, or several small conferences. For example, a conference device that was created with 20 streams would provide for one conference of 20 participants, or five conferences with four participants each (or any other combination that adds up to 20 total participants). The total number of conferences supported by each conference device is calculated by taking the total number of streams (for example, 20) and dividing by three. Therefore, in the example, you can have twenty divided by three (20/3) or six conferences supported by the conference device.


Caution Although conference devices can be installed on the same PC as the Cisco CallManager, we strongly recommend against this. If conference devices are installed on the same PC as the Cisco CallManager, it can adversely affect the performance on the Cisco CallManager.


Note Conference devices configured for software only support G.711 codecs, however, configuring for hardware provides transcoding for G.711, G.729 and G.723 codecs.

Two Types of Conferences: Meet-Me and Ad-Hoc

Cisco CallManager supports both Meet-Me conferences and Ad-Hoc conferences. Meet-Me conferences allow users to dial into a conference. Ad-Hoc conferences allow the conference controller to let only certain participants into the conference.

Meet-Me conferences require that a range of directory numbers be allocated for their exclusive use. When a Meet-Me conference is set up, the conference controller selects a directory number and advertises it to members of the group. The users call the directory number to join the conference. Anyone who calls the directory number while the conference is active, joins the conference. (This is true provided that the maximum number of participants specified for that conference type has not been exceeded, and sufficient streams are available on the conference device.)

Ad-Hoc conferences are controlled by the conference controller. The conference controller individually calls and adds each participant to the conference. Any number of parties can be added to the conference up to the maximum number of participants specified for Ad-Hoc conferences, and provided that sufficient streams are available on the conference device.

Ad-Hoc: How it Works

The user who initiates an Ad-Hoc conference is considered the conference controller. In an Ad-Hoc conference, only a conference controller can add participants to a conference. If other participants in attempt to conference, the Cisco CallManager ignores the signals.

When the conference controller initiates a conference call, the Cisco CallManager places the current call on hold, flashes the conference lamp, and provides dial tone to the user. At the dial tone, the conference controller dials the next conference participant and when the user answers, presses Conference again to complete the conference. The Cisco CallManager then illuminates the conference controller's conference lamp and connects the conference controller, the first participant, and the new conference participant to a conference bridge. Each participant's Cisco IP Phone display reflects the connection to the conference.

Participants can leave a conference by hanging up the conference call.

A conference continues even if the conference controller hangs up, although the remaining conference participants cannot add new participants to the conference.

Meet-Me: How it Works

The user who initiates a Meet-Me conference by pressing Meet-Me on the phone is considered the conference controller. The conference controller provides the directory number for the conference to all attendees, who can then dial that directory number to join the conference. If other participants in a Meet-Me conference press Meet-Me, the Cisco CallManager ignores the signals.

The conference controller selects a directory number from the range specified for the conference device. The Cisco CallManager Administrator should provide the conference directory number range to users so they can access the feature.

When the conference controller initiates a conference call by pressing Meet-Me, the Cisco CallManager flashes the conference lamp and provides dial tone to the user. At the dial tone, the conference controller can dial the conference directory number to create the conference. The Cisco CallManager then illuminates the Meet-Me lamp for the conference controller and connects the controller to the conference.

Participants can join the conference by dialing the specified directory number. The conference controller hears a tone each time a participant joins the conference. Participants can leave a conference by hanging up the conference call.

A conference continues even if the conference controller hangs up.
