Abstract

PURPOSE:To allow the system to recognize an incoming call from a specific caller during talking to be a specific call by registering incoming call control information stored on an IC card possessed by an extension subscriber to a storage device. CONSTITUTION:When an extension subscriber registers the incoming call control information, extension telephone sets 1-3 with a reader 11 are selected and a carried IC card is loaded to the selected telephone set. The incoming call control information commanding the control of incoming call to the telephone sets 1-3 is stored on the IC card. Then a selected extension telephone number and the incoming call control information are registered to a storage device 7 via an incoming call controller 15. While the telephone sets 1-3 whose incoming control information is stored in the storage device 7 are busy, when other incoming call comes, the incoming call processing is implemented and the content is displayed on a display device 12. Since the incoming call only by a specific caller registered in the storage device 7 is displayed, the call is recognized to be a specific call and the call is immediately replied.
