Abstract
A method (100) and system (20) for multiparty communication using at least one dual mode communication device includes a dual mode radio (11) having at least a first modem (12) for operation on a first network and a second modem (13) for operation on a second network and a processor (55) coupled to the radio. The dual mode radio can be programmed to establish (102) an interconnect call on a first network between the dual mode radio and a second communication device, receive (104) a request for a private call on a second network from a third communication device, and mix and route (106) audio from the private call and the interconnect call at the dual mode radio when a multiparty call mode is selectively chosen. The dual mode radio can be a first modem operating on a CDMA network and a second modem operating on an iDEN network.
