1. A method of controlling a conference call comprising the steps of: during a peer-to-peer, unmoderated conference call, detecting an in-band interrupt request signal initiated by a non-speaking conferee; automatically determining at least one conferee who is currently speaking; sending an alert signal to said currently speaking conferee, while preventing transmission of said alert signal and interrupt request signal to all non-speaking conferees; continuing to send said alert signal until a determination is made that said currently speaking conferee has taken a predetermined action; and discontinuing sending said alert signal upon determining said predetermined action has been taken.
