Abstract
Processing of dispatch calls in a multi-site communication system begins when a source communication unit initiates a request for a dispatch call. The request is routed to a controller which assigns a controlled device to support the request. In addition, the controller identifies the destination communication units, which site each of the destination units are in, and what controlled devices are needed to support the dispatch call. Having identified the controlled devices, the controller assigns all of the controlled devices needed the same temporary network address. With all the controlled devices having the same temporary network address, the controlled device assigned to support the request can transmit the messages generated by the source communication unit to other controlled devices using the temporary network address. Thus only one representation of a message produced by the source communication unit is transmitted from the assigned controlled device.
