Reservation system and method

A reservation system and method are provided that allow a user, who wants to receive a telephone inquiry or consultation service but cannot get through because an operator's line is busy, to reliably receive the service by making a callback reservation with a time or condition specified over the Internet without needing further telephone calls. The user enters customer information, such as a customer ID, name, and telephone number, and a reservation time or a reservation condition and makes a reservation. A reservation acceptance unit accepts the reservation from the user and notifies the user of reservation completion. When a user-specified time has come or a user-specified condition is satisfied, a reservation monitor unit notifies an operator of the reservation request to prompt the operator to call up the user. After the operator starts request processing, a reservation-request-processing update unit updates a processing status of the reservation request.
