A method of controlling conference calls includes initiating a conference call between multiple conferees using a conferencing controller, placing each of the multiple conferees in a listen only mode using the conferencing controller, receiving a signal at the conferencing controller from a plurality of the conferees requesting active participation in the conference call, displaying a list of the plurality of conferees requesting active participation in the conference call, receiving from a user a selection of one of the plurality of conferees who have requested active participation in the conference call, and placing the one of the plurality of conferees in a talk mode using the conferencing controller. The method may also include monitoring a connection between the conferencing controller and a controlling application and notifying an operator if the connection is disrupted.
