Abstract

PURPOSE:To inform instantly the absence to a caller by comparing subscriber information of an incoming call with subscriber information stored in a storage section so as to connect the incoming call to an annunciator when they are noncoincident. CONSTITUTION:An incoming call exists to a subscriber X when subscriber information Sx of an extension subscriber X is not registered in a storage section 81. A central processing unit 7 compares the information of the subscriber X in the information relating to the incoming call with all the subscriber information sets S1-Sn stored in the storage section 81 of the main storage device 8. After it is recognized that the subscriber information Sx of the subscriber X is not registered, the unit 7 connects the incoming call and the annunciator 6 via the switch network 4 to inform it to the caller from the annunciator 6 that the subscriber X is absent or unregistered. Thus, the absence is informed instantly to the caller.
