Internet telephone system, access point apparatus, and communication system using access point apparatus and broad-range data communication network

摘要

In an Internet telephone system, even though a user need not enter a user ID and a password, this internet telephone system can judge as to whether or not a telephone user is an authorized telephone user. To achieve this function, an Internet access point apparatus includes: a network interface unit functioning as an interface with a telephone line; a reception control unit for controlling the telephone line; a user data detecting unit for detecting user data and system data to thereby separate the user data from the system data; a calling telephone number detecting unit for detecting a calling telephone number sent via the telephone line to thereby recognize the telephone number of the telephone caller; an individual identifying unit for determining whether or not a telephone connection request is issued from an authorized telephone user on the basis of a detection result made by the calling telephone number detecting unit; and an output unit functioning as an interface with the Internet.
