Abstract (en)
[origin: WO0225908A2] Numerous packet-based terminals coupled within a packet-based network can establish a voice conference without the use of a conference bridge if the packet-based terminals can support specific operations. These specific operations include receiving voice data packets from each of the other packet-based terminals within the voice conference, determining a set of talkers within the voice conference and processing the received media data packets appropriately for the selected set of talkers so as to output uncompressed voice signals corresponding to the talkers to a speaker coupled to the packet-based terminal. the removal of the conference bridge can allow the packet-based apparatus to become independent from the packet-based network administration. Further, the removal of the conference bridge allows a reduction in transcoding and hence, allows a better quality signal to be received at the individual apparatus.
