2. Description of the Related Art In recent years, a service called groupware, which allows a registered group to share a schedule on a Web and access a telephone directory, an address book, and the like by using an ASP (Application Service Provider) method, has become widespread. Most mobile phones will be equipped with a web browser, and with the standardization of compact HTML (Hyper Text Markup Language) for mobile phones, it will be possible to create web pages that can be accessed by any business. Because of this, the sharing of schedules, telephone directories, address books, and the like on mobile phones is becoming widespread. Such a method of sharing a telephone directory and a method of registering and referencing data in a telephone directory are disclosed in Patent Document 1 and the like.
Applying these forms of mobile phone use to employees of companies and organizations is not only providing the necessary information to the necessary departments such as telephone books for customers, telephone books for internal use, etc. It is convenient to always provide new information.
[0003]
On the other hand, there is a problem that it is difficult to charge privately and publicly when a mobile phone is used by a company employee or an organizational staff, and as a solution, there is a method of connecting to a called party by callback.
Although it is different from callback, in order to prevent the user of the mobile phone from paying a charge, a toll-free service for the mobile phone is also provided, for example, when calling a call center from the mobile phone. However, at present, there are cases in which the service usage fee is high and the user bears the cost, and is not widely used.
In order to provide free or low-cost calls to mobile phone users from such a background, a system has been developed in which a line to be used is borrowed in advance at a low cost and a call back is made to connect to the call destination. Such a callback device is found in Patent Document 2 and the like.
