Lock or unlock the conference
The chairperson can lock the conference to prevent any new conferees from joining by dialing *4. The chairperson can unlock the conference allowing new conferees to join by dialing *4 again. A caller trying to join a locked conference hears an announcement indicating that the conference is locked. The system then disconnects the call. The chairperson can
Because there is one command for lock and unlock, the system announces to the chairperson one of two possible voice messages: “Meeting is locked” or “Meeting is unlocked.” Only the chairperson that activates the command hears the lock/unlock announcement.
Count conferees
The chairperson can count the number of conferees that have joined a conference by dialing *69 (for announcing to the chairperson only), or *60 (for announcing to the whole conference). The ICB card issues a string of voice prompts, one for each conferee in the conference, that only the chairperson hears. If a new conferee joins the conference after the chairperson activates the command, the ICB card does not count that new conferee. If the system drops a conferee after the “count the conferees” or “play list” command, they are counted, but not named.
When the chairperson dials *69/*60, the conferees hear a quiet click.
Table 35 on page 143 lists the TUI subcommands available to the chairperson when counting conferees.
