ABSTRACT:
When an optional communications device connected to a public network is entered as an extension terminal accommodated by a private network, the communications device sends a predetermined special number. If the service control device provided in the public network receives the special number, then it prompts the communications device for the identification information of a user of the communications device. At the prompt, the user transmits the user identification information from the communications device to the service control device. If the identification information is preliminarily entered, then the communications device sends a user number in the number system of the public network assigned to the communications device to the service control device. The service control device enters the user number as being associated with a predetermined number in a number system in the private network.
