| 1. A method for managing a packet switched, centralized conference call between terminals, said method comprising:
receiving streams of data packets from each of a plurality of terminals participating in a conference call, wherein each data
packet includes voice data or background noise information, and further wherein each data packet includes an identifier associated
with a respective terminal providing the data packet;
determining, based on the received data packets, if any of the plurality of terminals participating in the conference call
are currently providing voice data, and, if so, identifying each terminal currently providing voice data;
mixing voice data and background noise information included in the received streams of data packets to generate encoded combined
data;
inserting the encoded combined data into outbound data packets together with indicia identifying each terminal that provided
any voice data associated with the encoded combined data for each outbound data packet; and
streaming the outbound data packets to the plurality of terminals participating in the conference call.
