ABSTRACT:
In a radio communication system (100), radios initiating calls have their radio IDs stored by other radios in the radio communication system. The radio initiating the call can then send a voice request to a select one of the other radios in the system to establish a private conversation or other type of radio call (e.g., call alert, etc.) requiring the ID of the initiator radio. Since the other radios in the system automatically stored the ID of the radio initiating the call, they can establish a call with the initiator radio without even knowing that radio's ID number.
