Drop all conferees

The chairperson can drop all conferees from the conference, except the chairperson, by dialing *90. The ICB does not issue an announcement to the conferees before disconnecting. After the system disconnects the conferees, the ICB card issues an announcement to the chairperson indicating that there are no conferees on the conference. The announcement is followed by 60 seconds of music. The conference remains active, so conferees can dial in again.

Drop last dialed conferee

The chairperson can drop the last conferee to join the conference through dial-out by dialing *91. The chairperson can drop the last conferee to dial in by dialing *92. These commands are not repeatable (that is, the chairperson can drop the last conferee to dial in, but not the second-to-last to dial in). If the chairperson is the last to dial into the conference, the ICB card cannot execute the *92 command.

Conference duration expansion

The chairperson can expand the duration of a conference by 15 minutes by dialing *98. If the expansion is successful, the chairperson receives the voice message, “Your meeting duration has been expanded.” If the duration expansion is not successful, because there are not enough resources, such as ports or DNs, the chairperson receives the message, “Your meeting duration has not been expanded.”

The maximum conference duration, including all chairperson expansions, is 12 hours. The ICB card does not permit conference duration expansion to a conference scheduled to end within three minutes of the expansion request.
