Abstract
In a trunked communication system with at least two communication sites, a call hand-off mid-call may occur when a mobile radio (109) moves from the coverage area of one site to the coverage area of another site. This second site may not have any communication resources available for this hand-off, and the radio (109) is issued a busy message. With user selectable site switching, the user may enter into the radio (221) the desire to return to the previous site, and the radio moves to the previous channel to continue (229) receiving the call.
