Systems and methods for supporting dispatch communications with guaranteed talk permit and forced audio are provided. The systems and methods can include servers and communication units that operate according to the Push-to-Talk over Cellular (PoC) standard. A user of a communication unit can select a guaranteed talk permit with forced audio answer mode, and provide an indication of the answer mode to a PoC server. When the PoC server does not support a guaranteed talk permit with forced audio answer mode, this indication can be for a manual answer mode. Alternatively, the indication can be for a guaranteed talk permit with forced audio answer mode. In this case, a terminating communication unit is contacted during the dispatch communication setup even when the communication setup request is set to manual answer override.
