A system and method of retrieving dispatch call information from a dedicated database by using interconnect call information. Interconnect call information from an interconnect communication system is obtained. The information identifies a target dispatch subscriber unit in a dispatch communication system. A request is received from a source dispatch subscriber unit. The request includes the interconnect call information. The interconnect call information identifying the target dispatch subscriber unit is extracted from the request. The interconnect call information of the target dispatch subscriber is related to unique dispatch call connection information of the target dispatch subscriber in a dedicated database. The unique dispatch call connection information concerning the target dispatch subscriber unit from the dedicated database in the dispatch communication system is retrieved using the extracted interconnect call information from the request.
