<p>A conference bridge will receive incoming packet steams from multiple sources for a conference call. Packets within each of the incoming packet streams include audio signals from the corresponding source and source reference information, which uniquely identifies a source from which the packet was delivered. The conference bridge will identify one of the sources as an active source and deliver audio signals for the active source to the multiple sources in an outgoing packet stream. Packets in the outgoing packet stream will include active source reference information corresponding to the source reference information received for the active source. Based on the active source reference information, the sources may identify the source from which the audio signals in the outgoing packet stream correspond.</p> |
