Abstract
A typical multi-site trunked communication system comprises communication units that are arranged into talk groups, communication resources distributed among communication sites, and a communication resource allocator. In such a system, a methodology is incorporated that allows communication units to override communication site busy conditions, where the communication site busy conditions prohibits placement of group calls until all communication sites have an available communication resource. The communication site busy condition may be overridden by a communication unit by initiating a busy override signal. Once the busy override signal is initiated, the communication resource allocator allocates, in each site, a communication resource to the communication group of the requesting communication unit.
