Conference call Cisco

This document describes the steps used to set up a Meet-Me Conference and the details of how to use it in Cisco CallManager 3.x and 4.x.

Cisco recommends you have knowledge of these topics:

The information in this document is based on these software and hardware versions:

• Cisco CallManager 3.x and 4.x
• Cisco IP Phones 7910, 7940, 7960

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Complete these steps:

1. In the Cisco CallManager Administration page, go to Feature and select Meet-Me Number/Pattern.
2. Click on Add a New Meet-Me Number.
3. Configure a directory number or a pattern.

   Do not assign this number or group of numbers to any other IP phones, CTI ports, route points or pilot point. The number needs to be unique.

4. Click Insert.

Note: Cisco CallManager Software Conference Bridge supports only G.711 a-law and G.711 u-law and does not understand any other codec such as G.729. External callers cannot be added to the conference if they use a codec other than G.711. In order for calls that originate as G.729 to be connected with phones that use G.711, you need to use a transcoder.

In order to use the Meet-Me feature, go off-hook and press the Meet-Me button from your phone. Press the More softkey once in order to reach this Meet-Me. After you press the Meet-Me button, dial the conference number that you want to join. Everyone who dials the same Meet-Me number joins the conference together.

For example, some people decide to have a conference call at 17:00 hours and decide to use the conference number 1111 for the next thirty minutes. At 17:00, all the people who need to join this conference dial the Meet-Me number 1111. No one has to wait in order to be added to the conference. Also, when anyone drops out of the conference, the conference bridge still stays up.

Unlike the Meet-Me conference, the ad hoc conference is started by an initiator and only the initiator of the conference can add people into the conference.

There are two methods to use in order to initiate ad hoc conferences:

• Put a call on hold, dial another participant, and conference additional participants.
• Join established calls by using the Select and Join softkeys.
