The present invention makes it possible to connect to and communicate with a connect destination by using a temporary number. In the present invention, a temporary number user terminal (100) registers a temporary number acquired from a SIP account server (300) in a SIP proxy server (400), and connects to and communicates with a connected user terminal (200) by using the temporary number. After the communication is finished, the temporary number is unregistered from the SIP proxy server (400), thereby disabling a connection from the connected user terminal (200). Also, connection conditions are provided by specifying the validity period of connection using a temporary number, the number of times connection can be made, the connect destination to which connection can be made, and the like, and only those calls which meet the connection conditions are accepted, thereby making it possible to restrict the uses of the temporary number.
