ABSTRACT:
In the present invention, a target receiver terminal information storage unit stores a plurality of target receiver terminal numbers corresponding to a plurality of target receiver terminals. The control unit determines idle/busy information stored with a corresponding terminal number as a pair, selects a target receiver terminal number according to a predetermined priority, and outputs the selected number. A sender can thereby automatically call up an appropriate target receiver terminal by dialing a registered receiver identification number. The control unit uses connection information as well as idle/busy information as a determining element in selecting a number. Therefore, a registered number conversion service user can distribute calls to a plurality of target receiver terminals. Besides, the user can select a plurality of target receiver terminal numbers through an inquiry to a switching unit about the idle/busy state without storing idle/busy information or connection information in the storage unit.
