In extending wireless dispatch voice services to Internetworking Protocol (IP) client devices (such asPC's), a means of arbitrating push-to-talk is required to assure that only one participant in a dis- patch call can transmit at any given time. This arbi- tration should not be specific to a wireless system or systems which may or may not be present in an IP network dispatch call. IP clients should be able to conduct dispatch conversations with an arbitrary mixture of other IP clients and clients on wireless systems without requiring the presence of a specific wireless system. This calls for a distributed, peer- to-peer means of push-to-talk arbitration.
