Chapter 4 - Operations Performed During On Going Conferences

Using DTMF Codes in Cascading Conferences

During Cascaded conferences, the chairperson can control all the participants in the cascaded conference by performing the following tasks using DTMF codes:

•Set the chairperson as the conference’s exclusive speaker while muting all the other conference participants

•Terminate the conference

•Lock or unlock the conference to undefine dial-in participants

•Secure a conference and release a secured conference

•Place the conference on-hold and reinstate the conference

If the chairperson uses any other DTMF codes, only the participants in the chairperson’s local conference will be affected.

For more information on simple cascading, see the MGC Manager User’s Guide, Volume II, Chapter 1.

For a detailed description of H.243 Cascading conferences, see the MGC Manager User’s Guide, Volume II, Chapter 5.

Modifying Conference and Chairperson Passwords

During an On Going Conference, the Conference and Chairperson passwords can be modified by the chairperson or a participant (depending on the configured permissions) using DTMF codes from their endpoints (default DTMF code is *77). Passwords can also be modified by the operator via the MGC Manager. For more details, see “Modifying Conference and Chairperson Passwords” on page 4-68

When the chairperson activates the password modification process, the chairperson can select whether to modify the conference password or the chairperson password.

A sequence of voice messages and chairperson actions follows, to complete the password modification. Table 4-5 describes this sequence

If the chairperson or a participant exits without the password confirmation, the password is not updated.
