A communications system and method, which may be used, for example, within a conferencing communication system, is provided. A plurality of communicators may transmit, via a network, audio streams bound from any other communicator. A server receives from the plurality of communicators a plurality of incoming streams and for each communicator transmits any mixed combination of the incoming streams. The system also may control any of the mixers to independently control a volume level of any of the incoming streams being mixed at any of the mixers to create the required mixed combination of the incoming streams. Various conference call features may be effected using such mix capacities.
