A method of and system for managing a conference call among participants and a moderator provides a control mode in which only one participant can speak at time. All participants other than the speaker are muted. The system maintains a talk queue. When a participant requests to speak, the system places the participant in the talk queue. The system may announce to the moderator that the participant has registered to speak. The system may also announce to the moderator the participant's position in the talk queue. When a speaking participant relinquishes, or is preempted from, the speaking position, the system mutes the speaking participant. The system informs the participant at the top of the talk queue that it is his or her turn to speak and unmutes that participant, whereby that participant becomes the new speaking participant. The system removes the new speaking participant from the talk queue. The system may announce their respective positions to the other participants in the talk queue. The system may include priority codes. If a participant enters a priority code when he or she requests to speak, the system places the participant at the top of the talk queue. If the participant does not enter a priority code, the system places the participant at the bottom of the talk queue.
