A processor converts information signals into packet data suitable for transmission over a distributed network. The processor has identification information, and updates its identification information when the current identification information has to or is about to change. The processor then transmits its new identification information to the controller 104. The push-to-talk communication devices also comprise a transmitter to transmit packet data through a first channel to the controller. A receiver receives packet data through a second channel from the controller.
