The present invention relates to a keypad phone, and more particularly to a method for displaying an extension number of a keypad phone to display the extension number.

In recent years, with the development of software technology and hardware technology, the functions of the key system and the key phone are increasingly diversified, and the use of the key system and the key phone in the offices and hotels has been widely expanded.

And, by connecting a plurality of trunk lines, a plurality of extensions, and a plurality of extensions by one function of the above-described keyphone telephone, when a call is received from the outside through one trunk line, a keyphone telephone among the keyphone telephones sharing the curve. Even if the user can receive an incoming call.

In addition, as another function of the key-phone telephone as described above, when a call is received from another person, the caller enters the extension number of the key-phone telephone that the other person is using, so that the call is received from the outside. You can switch to the phone phone that the person is using.

For example, if the telephone number used by A is 100, the telephone number used by B is 200, and the call is made from the outside to the telephone used by B, and A is found. Since B knows the extension number of A, he enters extension number 100, and converts an incoming call from the outside to the phone phone A uses.

On the other hand, if you do not know the extension number of the key-phone phone to be switched, the person to be switched asks for the extension number of the key-phone phone of the person to be switched, and then switches the call from outside, or switches using a memo with the recorded extension number. Find out the extension of the phone you want to use.

At this time, when the person to be diverted is located in another place, and there is no knowing the extension number of the key-phone in the place, there is a cumbersome point to come to the place where the call is received from outside and to answer the call or to look up the note with the extension number recorded. .

For example, in the above example, if A is in the seat of another person C and does not know the extension number of the key-phone telephone used by C, A comes directly to the seat of B to answer the call, or B Find a note with the extension number and check the extension number of the C-phone that C is using to switch the call from outside to C's seat.

In addition, although there is a function of displaying an extension number by a user's operation among the functions of a keypad phone, there is a problem that the operation is complicated and inferior in speed.

Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide an extension display method of a key phone that displays an extension number when the key phone is in a call waiting state.

In order to achieve the above object, the present invention provides a method for displaying an extension number of a keypad telephone by a user's operation, the method comprising the steps of: storing the extension number transmitted from the key system in a memory; Checking that the keyphone phone is in the call waiting state provides an extension number display method of the keyphone phone, characterized in that the step consisting of displaying the extension number of the phone phone.

Other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a key-phone telephone capable of displaying an extension number according to the present invention, and is composed of a microcomputer 10, a memory 20, and an LCD 30 (Liquid CRYSTAL DISPLAY). do.

In the figure, the microcomputer 10 inputs an extension number transmitted from the key system to generate a control signal for storing in the memory 20, and checks whether the key-phone telephone is busy and is in a call waiting state. A control signal is generated for displaying the extension number from the key system stored in 20).

In addition, the memory 20 stores the extension number of the key-phone telephone based on the control signal for storage from the microcomputer 10, and the LCD 30 stores the keyphone based on the control signal for display from the microcomputer 10. The phone's extension number is displayed on the LCD.

2 is a flowchart illustrating an operation process of displaying an extension number of a key-phone in accordance with a preferred embodiment of the present invention. Hereinafter, the operation process of the present invention will be described in more detail with reference to FIGS. 1 and 2. do.

First, when a key phone is connected to the key system, the key system transmits the connected extension to the key phone.

Then, the microcomputer 10 of the keypad phone inputs an extension number transmitted from the key system (step 210), stores it in the memory 20 (step 220), and checks whether the keypad phone is busy (step 230). .

As a result of the check in step 230, if the key phone is in a call waiting state, the microcomputer 10 generates a control signal for displaying the extension number of the key phone stored in the memory 20, and returns to the microcomputer 10. The extension number of the key-phone telephone is displayed on the LCD 30 based on the control signal for display from step S240.

As described above, when the keypad phone is in a call waiting state, the extension number of the keypad phone is displayed on the LCD 30.

Therefore, by using the present invention, since the user can easily know the extension number of the key-phone telephone, there is an effect that can provide the user's convenience when the call is transferred during the key-phone telephone period.
