A communication system ( 100 ) includes a first communication unit ( 101, 102, 103, 104 ) capable of communicating over a full-duplex persistent-connection link provided by a full-duplex network ( 105 ) and a second communication unit ( 151, 152 ) capable of communicating over a half-duplex dispatch link provided by a dispatch RF system ( 150 ). The system ( 100 ) also includes a dispatch gateway ( 120 ). The dispatch gateway ( 120 ) receives signals from a first communication unit ( 101, 102, 103, 104 ) over a full-duplex persistent link through a full-duplex network ( 105 ) and provides communication between the first communication unit and a single dispatch communication unit ( 151, 152 ) or a group of dispatch communication units ( 151, 152 ) over a half-duplex communication link through a dispatch RF system ( 150 ). The gateway operates in a manner so as to permit communication between full-duplex terminals ( 101, 102, 103, 104 ) and half-duplex terminals ( 151, 152 ).
