A method and apparatus are provided for reducing truncation of time sensitive information such as audio in a trunked radio system having a plurality of zone controllers. The method includes the steps of receiving a call request from a calling radio or wireline console by a controlling zone controller of the plurality of zone controllers and measuring a time necessary to set up a call connection between the controlling zone controller and a plurality of called radios or wireline consoles where the call connections of the plurality of called radios or wireline consoles are each set up through a different participating zone controller of the plurality of zone controllers. The method also includes the steps of determining a largest relative measured time among the measured times and buffering audio information from the calling radio for a time period proportional to the determined largest relative time.
