US Patent 7751543 System and method for button-independent dispatch communications

Systems and methods for button-independent dispatch communications are provided. A dispatch station monitors a microphone input to determine whether it provides voice information. When the input provides voice information, the dispatch station then determines whether the floor of the dispatch communication is open. When the floor is open, the dispatch station seizes the floor and transmits the voice information. When the floor is not open, the dispatch station can store the voice information and transmit it once the dispatch station is able to seize the floor.
