In the following invention, the callback service of a subscriber who has subscribed to the callback service is referred to as a "code register service". It is called.

The code register service method is a method in which a subscriber applies for a service to a callback service provider in advance, registers his or her callback service number (the code register number "CRN" to be used by receiving the callback service provider from the callback service provider, and uses the service. To allow customers with frequent overseas trips, such as travelling, to use international calls at low rates to save call rates, so that subscribers can call their callback service numbers from abroad and use the low cost callback service line to exchange international exchanges. After accessing the domestic callback service system subscribed to the user, leaving the phone number to be contacted and terminating the connection, the callback service system searches the previously established database and accesses the CRN registered by the subscriber. Go out-going to your contact number It is a service that connects particle and CRN call.

3 is a view illustrating a callback service method by a non-subscriber according to another embodiment of the present invention, wherein a callback service of a user of a callback service system not subscribed to the callback service is referred to as "callback center service" in the following invention. It is called.

The method of providing a callback service to a user (CALLER) who does not subscribe to the callback service; When a non-subscribed user accesses the callback service number previously released by the callback service provider, the callback service provider sends out a message for inputting a phone number and a call request phone number to be contacted through voice mail, and also inputs a user's card number and password for billing. Send out the message. When the user terminates the connection after all of the user inputs, the callback service system connects the call by out-going to the user contact number after the user connects to the desired telephone number.

Although not shown, the services provided by the callback service system include additional services and callback machine services.

The additional service is a kind of mail service, and provides a call back service subscriber with a voice mail box, a fax mail box, a conference call, a personal registration information guide, and an automatic answering function. Such callback service subscribers can receive services at low cost in Korea or abroad.

The callback machine service is to provide a callback service to a user who wants the callback service more conveniently. The user can carry a mobile DTMF Tone Generator with a callback service number inputted in advance, Pressing a specific key on the DTMF Tone Generator (for one user's convenience), when the DTMF is generated, it automatically attempts to connect to its own callback service number or callback service center to the code register service or callback. This service allows you to use the center service.

The use of international calls for saving call rates using the above-described callback service system will be described in detail with reference to the accompanying drawings.

First, a "code register service" method, which is a callback service of a subscriber who subscribes to a callback service according to an exemplary embodiment of the present invention, will be described with reference to FIG. 2.

The callback service subscriber calls his callback service number (step 301).
