An ID pool server(20-1) is connected with a transmitter's terminal(21) for performing the VoIP call by an SIP manner through the Internet network. The ID pool server offers and receives the common ID to/from the transmitter's terminal. An SIP(Session Initiation Protocol) server(20-2) is connected with the transmitter's terminal through the Internet network and performs a call processing procedure relating to the transmitter's terminal for attempting a call connection by means of the common ID offered by the ID pool server. The ID pool server manages each common ID by the state display manner such as unavailable and available. A gate way is connected with the SIP server through the Internet network, connected with the receiver's terminal through the telephone network and performs the signal exchange between the Internet network and the telephone network.
