A Meet-Me Conference has four states:
Conference inactive: Currently, there are no callers in the conference.
Conference not started: Participants have arrived, but the moderator has not joined the conference. In this phase, participants wait on hold and cannot speak to one another.
Conference in progress: The moderator enters the conference. An entry tone is heared when individual participants joins into the conference in the order in which they dialed into the conference. Participants can now speak to each other, subject to mute and other moderator functions.
During the conference, the status displays the elapsed time of the conference (in minutes) and the number of participants. New participants can join the conference unless the moderator locks the conference. See Enabling lock meeting in Meet-Me Conference.
Conference terminated/ended: A conference ends after the last person hangs up.
By default, the conference ends as soon as the moderator leaves the conference.
When the Conference Continuation option is enabled, conferences continue after the moderator leaves the conference.
