As society develops, the amount of information that individuals manage increases. With this increase in information, it is difficult for each individual to manage his or her information, which is difficult to manage depending on his memory. In addition, you can manage the database by using a document or a computer by yourself. Building a database using a document can be cumbersome when the contents of the information change, and the document becomes messy. It may be missing. There is also a risk of documents being lost.

And while using a computer to manage data can be very effective, it's not so effective for people who aren't used to it.

But the phone is a tool that many people find handy. On the other hand, telephone is not enough to handle a lot of information. Therefore, in order to solve this problem, a conventional computer telephony integration (CTI) has been proposed to manage information by integrating a telephone and a computer. Or, the user is configured to be serviced by operating the phone button. When a user is provided with information through a guide, the user himself or herself delivers the information to the guide, which may cause information leakage, and may cause inconvenience and disputes due to an error in the guide. In addition, when a user operates a button to receive a service, it is inconvenient to reoperate the button in case of an input error.

In addition, the user should have all the relevant information directly when the user operates a guide or operates a button. When a telephone connection request is not remembered, many telephone numbers are not remembered, so it is inconvenient to own and find by using a document or other storage method, and information inconvenience is caused.

In addition, the service provider needs training for the guide when the new service is introduced, and there is a disadvantage in that the cost is further generated because the adaptation period is required in addition to the training cost when the guide is replaced.
