Abstract
A cellular telephone having a transceiver for making cellular telephone calls is equipped with a second transceiver for establishing communication with other devices having similar capabilities. The cellular telephone uses the second transceiver to establish a local voice channel with another communication device, and combines it with a cellular call to create a multiparty conference call. A mixer mixes voice from the call and local voice channel. The second transceiver implements a local area wireless protocol.
