摘要

A transfer unit transfers a message between a network and an external terminal. An input unit inputs a user ID for identifying a user. A generating unit generates a registration message requesting a registration of address information of the user. A transmitting unit transmits the registration message to a server. A receiving unit receives a response message including registration information and connection information from the server. When the connection information indicates a permission of a connection of the external terminal to the network, a control unit controls the transfer unit to transfer the message between the network and the external terminal.

主权项

1. An Internet-protocol phone terminal that mediates a connection between a computer terminal and a network comprising:
an Internet-protocol phone processing unit that provides an Internet-protocol phone function by registering address information, which is information for identifying a user, for specifying the user as a communication destination to a server that is connected to the Internet-protocol phone terminal via the network; a first interface that connects to the network; a second interface that connects to the computer terminal; and a transfer unit that
transfers a message between the network connected through the first interface and the computer terminal connected through the second interface,transfers a message between the network connected through the first interface and the Internet-protocol phone processing unit, andtransfers a message between the computer terminal connected through the second interface and the Internet-protocol phone processing unit, wherein the Internet-protocol phone processing unit includes:
an input unit that inputs a user identification not from the computer terminal, which is information for identifying the user, to be used for an authentication of the user;a generating unit that generates a registration message requesting a registration of the address information of the user identified by the user identification input by the input unit;a transmitting unit that transmits the registration message to the server;a receiving unit that receives a response message including registration information indicating availability of the registration of the address information and connection information indicating availability of a connection of the computer terminal to the network from the server, the response message indicative of a permission for connection of the computer terminal to the network, and the connection being a connection for transmitting a message other than a message that is transmitted by the Internet-protocol phone function; anda control unit that
controls the transfer unit not to transfer a first message between the network connected through the first interface and the computer terminal connected through the second interface before the receiving unit receives the response message, the first message being a message other than the message that is transmitted by the Internet-protocol hone function, andcontrols the transfer unit to transfer the first message between the network connected through the first interface and the computer terminal connected through the second interface after the receiving unit receives the response message; and the Internet-protocol phone processing unit provides, when the registration of the address information is permitted, the Internet-protocol phone function, which is specific to the user that is identified by the address information.
