Abstract

PURPOSE:To reject the reception by registering a prescribed caller number as an incoming reject number and registering a malicious call as an incoming reject number when the malicious call including a caller number in a setup message is received. CONSTITUTION:A caller number detection means 661 detects a caller number in a setup message at the arrival of a call, stores the caller number and registers the number to a caller number registration means 664. When the caller number is registered, a caller number check means 663 compares a number already registered with the caller number in the setup message at the arrival of the call. When the detection means 661 detects that the caller number is included in the setup message and the number is coincident with the registered number, a call release means 662 sends a message to reject the acceptance of the call. When the caller number is not included in the received message at the arrival of the call, the arrival of the call is rejected and when a malicious call including the caller number is received, the number is registered as the incoming reject number. When the setup message including the caller number is received, the arrival of the call is rejected.
