PROBLEM TO BE SOLVED: To provide a telephone terminal which can be used for a purpose for making terminal equipment connected to the Internet join in a sound call between two persons and making the sound call among three persons. SOLUTION: In a compound machine functioning as the telephone terminal, a transfer operation is performed in a processing of s240 in a state where a line with the telephone terminal is connected in a processing of s170. Thus, connection is requested from an Internet terminal in a processing of s270. When an Internet terminal response is given for the request (in a processing of s280), the line with the terminal can be connected. Sounds based on sound signals inputted/outputted between both terminals are inputted/outputted to/from a transmitter and the like after such a state. Thus, the sound call among the three persons by the compound machine and both terminals is realized. COPYRIGHT: (C)2004,JPO
