Nortel Integrated Conference Bridge Service Implementation Guide
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.
