An exchange control portion and a service control portion are provided on the exchange network' side. The service control portion is provided with a PTN management table. When a subscriber dials a special number, the service control portion is activated. Thus, the service control portion sends to the subscriber a command for requesting him to input his PTN. When the subscriber inputs information identifying his PTN, the service control portion controls data relevant to the subscriber. When the service control portion receives the PTN of a receiving subscriber according to the input command thereof, it detects the telephone number of the receiving subscriber using the PTN management table. Thereby, the exchange control portion connects the subscriber to the receiving subscriber using the telephone number received or detected.
