ABSTRACT:
An apparatus and method for issuing busy call-backs (146) on the voice channel to busied communication units (209,211) on a trunked radio communication system (200) is disclosed. This is accomplished, in part, by issuing a busy signal (104), via a control resource (203), to a communication unit when a requested communication resource is unavailable. Additionally, the radio communication unit (209,211) is capable of receiving the busy signal via the control resource (213) and participating in a second communication while in a busied state. The resource controller (201) is capable of allowing the busied communication unit (209,211) to participate in a second communication on a second communication resource (215) and issuing the call-back signal during the second communication.
