The present invention relates to a call storing method of a keyphone system, and more particularly, to store a call of an incoming call, and to connect with a call of a stored call that is received and stored in a general telephone or a key phone. It relates to the storage method of the lake.

The user of the conventional key phone system used to switch to a key phone phone to talk to the trunk line received from a general phone in addition to the key phone during the call.

However, the other party using the CO line has a problem in that the call to be diverted is busy or if the wrong number is entered, the current CO line should be terminated and redialed to connect the call.

Accordingly, an object of the present invention is to provide a call storage method of a key phone system capable of storing a call of a trunk line received in a key phone system and performing a call with a call of a trunk line received and stored in a general telephone in addition to the key phone telephone. Call storage method of a key phone system according to the present invention for achieving the above object comprises the steps of restarting when the call is not busy by determining whether the trunk line of the key phone telephone; Determining whether a call storage signal is input when the key phone is busy and restarting when the call storage signal is not input; Notifying a code for storing a call to the outside through the output unit when the call storing signal is input in the step so that the user of the key-phone telephone can recognize it; Storing a call of a trunk line received at the code when a code for storing a call is generated from the outside; Determining whether the hook of the general telephone is 'off' after storing the call of the trunk line received at the step; Judging whether the extension signal is input when the hook of the telephone is 'off' as a result of the determination in the above step, and restarting when the extension signal is not input; Determining whether a storage code is input by a key-phone telephone user or a general telephone user when the hook of the telephone is 'off' or an extension signal is input, and restarting when the stored code is not input; When the code stored in the above step is input by the key-phone telephone user or the general telephone user, it is provided with a step of connecting a call of the trunk line which is received and stored.

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

1 is a block diagram for call storage of a key phone system according to the present invention.

The block diagram of the key phone system includes a key phone telephone 100 including a main device 10, a general telephone 20, an input unit 30, a control unit 40, a storage unit 50 and an output unit 60. .

In the above, the main device 10 is connected to the trunk line to receive the trunk line from the outside. In addition, the main device 10 is connected to the general telephone 20 is given a plurality of predetermined unique number. Therefore, a call is made by connecting with a predetermined unique number according to a signal input from the outside through the trunk line.

The general telephone 20 is connected to the main device 10 and receives a call signal output from the main device or transmits a signal generated according to a manipulation of the dial part of the user of the keypad phone 100 to the main device. The input unit 30 mounts a plurality of buttons and outputs a signal corresponding to the operation of the user of the keypad phone 100. In particular, a call storing button is mounted, and the trunk line to which the user of the keypad phone 100 is received. When the user wants to store the call of the phone 100, the user operates the call storing button and outputs a call storing signal for storing the incoming call.

The controller 30 receives each signal output from the input unit 20 and outputs a control signal. If a signal for storing a call of an incoming call is input for the user's manipulation of the key-phone telephone 100, a code to be stored is read to output a control signal for storing the call of the incoming call. The controller outputs a control signal so that the call can be made by connecting with the stored CO line.

The storage unit 50 receives a control signal from the control unit 30 and stores a call of the incoming trunk line in a predetermined code, so that a user of the keypad phone 100 who wants to receive a call with the incoming trunk line is stored in a keyphone telephone or a general telephone. When the preset code is input, the incoming and stored call of the CO line is read.

The output unit 60 receives a control signal from the control unit 40 and uses a liquid crystal display (LCD) or the like so that the user of the key-phone telephone 100 can recognize the code storing the incoming call. Indicates.

2 is a flowchart illustrating a call storage method of a key phone system according to the controller 40 of FIG. 1 step by step.

First, when a CO line signal is input from the outside via a CO line, it is operated by a key-phone telephone user to determine whether a call is made and restarts when the CO line is not in a call.

Next, in step 200, the caller using the keyphone determines whether a call storing signal is output by operating a call storing button mounted on the input unit 30 to store the call of the incoming call when the CO line is busy. If the call storage signal is not input, it is restarted. (202) Then, when the call storage signal for storing the incoming trunk line is input in step 202, a code for storing a call of the incoming trunk line is stored in the storage unit 50. It reads out and displays the screen so that the user of the keypad phone can recognize it through the liquid crystal display of the output unit 60 (204).

Next, in step 204, the storage unit 50 reads the storage code, outputs it to the outside through the output unit 60, and stores the call of the incoming trunk line in the predetermined code of the storage unit 50. (206) Then, after the call of the trunk line received in step 206 is stored in the storage code of the storage unit 50, the hook of the ordinary telephone 20 connected to the main device 10 is connected to the ordinary telephone 20 user. Determine if 'off' by (208).

Next, as a result of the determination in step 208, when the hook of the general telephone is not 'off', the user of the keypad phone operates the input unit 30 to determine whether an extension signal is generated and restarts when the extension signal is not input. (210)

Subsequently, when the hook of the ordinary telephone is 'off', as determined by the step 208, the stored code pre-stored the call of the trunk line received through the input unit 30 by the user of the keypad telephone or the telephone user. It determines whether it is input and restarts when the storage code is not input (212).

Then, when the code storing the call of the incoming trunk line in step 212 is input by the key-phone telephone 100 user or the general telephone user, the incoming trunk line and the key-phone telephone 100 user or the general telephone user are connected. Enable Calls. (214)

Therefore, the present invention has the advantage of storing the call of the trunk line received in the key phone system to conduct a call with the incoming trunk line in a general telephone in addition to the key phone.
