Abstract
A telephone system using terminals in computer network connected via servers to transmit data containing at least audio data through the computer networks. A server is provided with a data base storing call-out information used to connect to a destination terminal. When a source terminal makes a call to a destination terminal, the server of the computer network searches out the connection address of the destination terminal from the data base. Then, the server calls up the destination terminal and establishes connection between the server of the computer network and the destination terminal.
