Incoming call notification apparatus

Abstract

An incoming call notification apparatus which is capable of notifying an operator of a called terminal of an incoming call received when the terminal was not capable of answering an incoming call. When a terminal calls another terminal which is in use or in communication with still another terminal, an incoming call information storage apparatus stores incoming call information of the incoming call. When the called terminal becomes capable of accepting a call, a call setup message transmission apparatus reads out the stored incoming call information, produces a call setup message containing the incoming call information, and then transmits the call setup message to the called terminal. A disconnect apparatus executes incoming call abortion processing after completion of a calling (ALERT) sequence carried out in response to the call setup message during the incoming call processing.
