CONSTITUTION: A reception-side terminal registers a telephone number and bell sound list having authority capable of changing a bell sound in a service provider server(S101,S102). If a caller inputs a reception-side telephone number(S103), the service provider server detects a caller's number and judges whether the caller's number is a telephone number having the bell sound change possible authority(S104). If the caller's number is the telephone number having the bell sound change possible authority, the service provider server outputs a bell sound selection guiding message(106). If the caller listens to the bell sound selection guiding message and selects a desired bell sound number(107), the service provider server loads the selected bell sound from a database(108) and transmits the loaded bell sound together with a call connection signal to the reception-side terminal(S109). The reception-side terminal reproduces the bell sound as soon as the bell sound is received(110).
