TELEPHONE NUMBER MANAGEMENT SYSTEM

PROBLEM TO BE SOLVED: To provide a telephone number management system capable of preventing the outflow of such personal information as telephone numbers, and making a telephone call to a destination efficiently and quickly. SOLUTION: In a telephone number management server 100, when a notification request of a temporary number to a destination is received, a one-time number management part 160 generates the temporary number to the destination, and transmits the generated temporary number to the telephone terminal of the destination of the request. Further, when the destination temporary number and a regular number of the caller are acquired from the telephone terminal side of the addresser, the one-time number management part 160 changes the destination temporary number into the regular number, and notifies the regular numbers of the caller and the destination to a switching system.
