Managing an MCU conference call

Last Updated : Dec 10, 2025 |

About this task

With an MCU license, you can use the codec as the conferencing unit and manage conference calls from the GUI menu. You can create a conference by establishing a two-party call and then adding more participants from the codec Conference menu. You can access conferencing options by pressing the Menu button on the remote control during a conference call.

From the Conference menu, you can add or remove participants, select the conference mode, mute codec and participant audio, disable or enable the camera, and send a presentation from the connected video source. You can also view the list of participants and general call information.

You can join a conference call in the following ways:

  • By accepting an incoming call from the codec. The conference host adds participants during an active conference call.

  • By directly calling the codec with an installed MCU license using the codec IP address or registered SIP or H.323 account.

Before you begin

Ensure that you have done the following:

  • Purchased an MCU license from Avaya. For more information about purchasing the MCU license, contact Avaya Support.

  • Joined or started a conference call from the Meeting menu.

  • Connected a video source for presentation sharing, such as a computer or HD camera, if you want to send a presentation to the conference call participants.
