Abstract

Methods, apparatus and computer system for efficiently utilizing a conference bridge capacity in order to support a multipoint conference call are described. Each conference bridge within multiple communication groups determines which local communication unit is a dominant local communication unit, quantizes that dominant local communication unit's signal, and transmits the quantized signal of the dominant local communication unit via signaling channels to the other conference bridges. Each conference bridge then compares the various quantized signals of the various dominant local communication units to determine an overall dominant communication unit of the multipoint conference. Then the signal of the overall dominant communication unit is then transmitted to all communication units participating in the conference call in various ways for different embodiments of the invention.
