PROBLEM TO BE SOLVED: To allow a number allocated to a user mobile telephone terminal to be usable for calling from an arbitrary telephone terminal.SOLUTION: A communication device includes a receiver unit, a transfer condition table, a conversion unit and a transmitter unit. The receiver unit receives a call request. In the transfer condition table, there are registered a user number, a calling source number, and a transfer destination number, each associated to a target number which is a telephone number designated to be the calling destination of a transfer processing target. The user number is a terminal number owned by a user using the target number. The calling source number is a telephone number of a use terminal, which is a terminal for use to call the target number. The transfer destination number is a telephone number allocated to the transfer destination of a call from the use terminal. The conversion unit converts the calling source to the user number on acquisition of a call request from the calling source number to the target number, to convert the calling destination into the transfer destination number. The transmitter unit transmits to the calling destination a request message to request calling from the user number to the transfer destination number. |
