Abstract
Abstract A combination radio/telephone transceiver (40) receives a selective call signal over a selective call channel and searches for its assigned address (415). When the assigned address (415) is found, a message (405) associated therewith is decoded and stored, and the signal is further examined to determine whether the message (405) has been flagged for acknowledgment, such as by appending a predetermined ackback flag (425) or a predetermined ack address to the address (415) assigned to the combination radio/telephone transceiver (40). When no acknowledgment is requested, i.e., when the message (405) has not been flagged for acknowledgment, the combination radio/telephone transceiver (40) does not acknowledge reception of the message (405). When the message (405) is flagged for acknowledgment, the combination radio/telephone transceiver (40) acknowledges reception of the message (405) via a telephone network rather than over the selective call channel.
