Abstract
A telecommunication conferencing system and method are described. Three or more telephone sets connected to one of the networks can concurrently participate in a conference call. Each telephone set engaged in the conference call receives a list of participants in the call and an identifier associated with that call. Each telephone set generates voice data packets that include the identifier and forwards the generated packets to the network. In one embodiment, the telephone set generates a unicast packet for each other telephone set engaged in the conference call. In another embodiment, the packets generated by the telephone set are multi-cast packets that include the identifier associated with the conference call. Each telephone set locally produces a combination of the packets received and outputs audio signals corresponding to the voice data of the combination.
