Among the changes in the role of the digital portable terminal, the first proposed, implemented and widely applied function is a phonebook management function called a phonebook function. The function is to pre-register a phone number and corresponding name information required by a user in advance. After storing, it was performed as an operation performed to retrieve and use the stored phone number as needed.

By the way, these mobile communication terminals are relatively expensive compared to landline telephones, but since the phone book of the mobile communication terminal stores a lot of phone numbers, the user can conveniently search for the desired phone number from the mobile terminal and make the call immediately. Because of this, I don't use a landline phone to intentionally dial a phone number separately.

Accordingly, an object of the present invention is to provide an automatic call method of a wired network telephone that can call a phone number of a mobile communication terminal or a personal digital assistant (PDA) phonebook without manually dialing a general wired network telephone using Bluetooth communication. .
