Abstract
Abstract A communication unit (103) transmits a concurrent monitoring request to a base station (102). Responsive to the concurrent monitoring request, the base station provides multiple communications from at least one dispatch position (101) and at least one other communication unit (104) to the communication unit. Upon reception of the multiple communications, the communication unit simultaneously renders the multiple communications audible, allowing an operator of the communication unit to concurrently monitor the multiple communications.
