METHOD FOR SERVICING AN AUTOMATIC MULTILATERAL INTERNATIONAL COLLECT CALL, ESPECIALLY RELATED TO SIMULTANEOUSLY MAKING CALLS BETWEEN AN OVERSEAS CALLER AND PLURAL DOMESTIC RECEIVERS IN COLLECT CALL SERVICE TYPE
PURPOSE: A method for servicing an automatic multilateral international collect call is provided to simultaneously connect an overseas caller with plural domestic receivers through a collect call telephone service, so that many people can simultaneously make calls while PSTN resources are saved. CONSTITUTION: When a caller is connected, an automatic multilateral international collect call system delivers another announcement for collecting desired receiving numbers to a telephone of the caller(S210,S220). If the caller presses plural receiver telephone numbers, the system decides whether the telephone numbers are available(S230,S240). If so, the system temporarily stores the telephone of the caller with telephones of receivers, and decides whether the receivers permit a collect call service(S250,S260). If so, the system simultaneously connects the telephone of the caller with the telephones of the receivers, and requests the receivers to pay for telephone charges(S270,S280).
