Abstract

PURPOSE:To make it possible that the operator of an absent extension calls the calling subscriber of incoming call in absence at an arbitrary time, by storing the calling extension and the terminating extension concerning incoming call to the extension telephone which performed absence registering. CONSTITUTION:Absence registering to cause control unit CCU to recognize that extension STA-A to be absent is absent after that is performed for memory unit MEM of the automatic private branch exchange unit, and calling extension STA-B and terminating extension STA-A are stored in MEM concerning incoming call to extension STA-A which performed absence registering. Then, the operator who performed absence registering discriminates whether incoming call to the extension, which performed absence registering, in absence exists or not from an arbitrary extension on the basis of contents of memory unit MEM, and calls the calling subscriber of incoming call if incoming call exists.
