Abstract: A method of setting up a teleconferencing system using mobile devices is disclosed. Participants with mobile devices in multiple rooms may communicate based on the disclosed teleconferencing application executed on the mobile devices. Each room has one of the mobile devices designated as a leader device for that room. The leader devices may communicate using VoIP over the Internet. Other mobile devices in a room are designated as client devices associated with the leader devices. Participants operating the client devices can talk to other participants in that room and the other rooms through the client device communicating through the leader device of the room. The leader device synchronizes the playing of received audio between all of the client devices in the room. The leader device includes a selection algorithm that selects one of the devices to act as the microphone for audio signals generated in the room.
