Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and a device for performing a voice dispatch call in a digital communication system such as spread spectrum communication system. SOLUTION: When a call originating mobile unit sends a dispatch request and the request is received in a dispatch server (305), the dispatch call is started. A radio channel is established with each of active mobile units in a dispatch group (307). Next, the call originating mobile unit sends audio data and these data are received by the dispatch server (309). The audio data can be held in a buffer in the call originating mobile unit or dispatch server. Next, the dispatch server distributes one part of audio data to the active mobile unit in the dispatch group while utilizing the radio channel (311).
