Description

How to send a voice message when the extension is switched on the key phone system

The present invention relates to a method for transmitting a voice message during extension switching in a key phone system, and more particularly, to a method for transmitting a stored voice message during extension switching in a key phone system.

In the conventional key-phone system, if a caller receives a call from someone other than the caller, the paging button is pressed during the extension, and the caller is called ○○. do. Therefore, there is a problem in the subscriber system that the subscriber must speak the extension subscriber directly, as described above, every time the extension is switched in the key phone system. In addition, there is a problem that the listener does not hear well when the voice of the person speaking the voice message is small when the extension.

Accordingly, an object of the present invention is to provide a method for transmitting a voice message during extension switching in a key phone system.

Another object of the present invention is to provide a method for storing a voice message frequently used in a key phone system in advance and transmitting the voice message when the extension is switched.

The present invention to achieve these objects is stored in advance in the voice message frequently used in the key phone system, if the voice call button for playing the stored voice message is pressed, when the extension is corresponding to the telephone extension number The voice message is transmitted through the voice output unit of the key phone terminal.

1 is a block diagram of a key phone system to which the present invention is applied.

2 is a view showing a control flow for transmitting a voice message when the extension in the key phone system according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings according to a specific embodiment of the present invention will be described in detail.

1 is a block diagram of a key phone system to which the present invention is applied, and includes a key phone main device 100 and key phone terminals 110, 120, ..., 12 n.

Referring to FIG. 1, the key phone main device 100 includes a trunk line connection unit 101, a switching unit 102, a control unit 103, a ROM 104, a RAM 105, and a message storage unit 106. The switching unit 102 measures the trunk line through the trunk line connecting unit 101, and connects the key-phone terminal of the corresponding extension number under the control of the controller 103. The controller 103 performs an overall control operation of the key phone main device 100. That is, the controller 103 controls the operations of the switching unit 102, the RAM 105, and the message storage unit 106. The ROM 104 stores programs necessary for the operation of the key phone main device 100, and the RAM 105 stores or outputs various data according to the operation of the key phone main device 100. The message storage unit 106 stores and outputs a voice message under the control of the control unit 103. The message storage unit 106 according to an embodiment of the present invention stores a voice message repeatedly used by an extension subscriber in extension switching in a key phone system. For example, the message storage unit 106 according to an embodiment of the present invention stores a voice message, such as Mr. Mr. ** call.

On the other hand, the key phone terminals 110, 120, ... 12n are key phone telephones or general telephones, and are composed of a main device connecting portion 111, a control portion 112, a ROM 113, a RAM 114, an operation portion 115, and an audio output portion 116. The main device connecting section 111 is connected to the trunk line connecting section 101 in accordance with the switching operation of the switching section 102 of the key phone main device 100. The controller 112 performs an overall control operation of the keypad terminal 110. That is, the control unit 112 controls the operations of the main unit connecting unit 111, the RAM 114 and the audio output unit 116. The ROM 113 stores a program necessary for the operation of the key phone terminal 110, and the RAM 114 stores or outputs data according to the operation of the key phone terminal 110. The operation unit 115 is composed of a plurality of buttons for selecting the operation of the keypad terminal 110. The operation unit 115 according to the embodiment of the present invention includes a voice call button for requesting to reproduce and output a voice message. The voice output unit 116 is a receiver of a speaker or a telephone and transmits voice data and a ring signal. That is, the voice output unit 116 transmits a voice message according to an embodiment of the present invention.

2 is a flowchart illustrating a control flow of transmitting a voice message during extension switching in a key phone system according to an exemplary embodiment of the present invention.

1 and 2, in step 202, the controller 103 detects that a trunk line is received by the trunk line connecting unit 101 through the switching unit 102. In step 204, the control unit 103 detects that the phone terminal 110 occupies the trunk line. That is, the keypad terminal 110 is connected to the trunk line connecting unit 101 according to the switching of the switching unit 102 through the main unit connecting unit 111 to occupy the incoming trunk line. In step 206, the controller 103 determines whether the extension is switched at the key terminal 110 occupying the incoming trunk line. That is, the phone terminal 110 detects that the hook-off switch or the extension button is pressed for another extension. If the hook-off switch or extension switch button for extension is not pressed, it is determined that there is no extension according to the embodiment of the present invention, and the control operation for transmitting the voice message is terminated.

On the other hand, when the hook-off switch or the extension button to switch the extension according to an embodiment of the present invention is pressed in step 208, the control unit 103 determines whether the voice call button is pressed in the key phone terminal 110. When the voice call button is not pressed, the control unit 103 detects that the corresponding extension telephone number for extension switching is input and applies a ring signal to the key terminal of the extension telephone number. That is, if the corresponding extension number is 102 and the key phone terminal of the corresponding extension number is 120, the controller 103 controls the switching unit 102 to transmit a ring signal to the key phone terminal 120. In addition, when the voice call button is not pressed, the controller 103 ends the control operation for transmitting the voice message when the extension is switched in the key phone system according to the embodiment of the present invention.

In contrast, when the voice call button is pressed, the controller 103 detects that the corresponding extension telephone number for the extension is input in step 212 and applies a ring signal to the key phone terminal of the extension number. That is, if the input extension number is 102, the controller 103 controls the switching unit 102 to transmit a ring signal to the key terminal 120 of the extension number. In step 214, the controller 103 detects that the extension is switched to the key terminal 120 of the corresponding extension number. That is, the controller 103 detects that the key terminal 120 of the corresponding extension number is hooked off and determines that the extension switch has occurred. In step 216, the control unit 103 transmits the voice message stored in the message storage unit 106 to the key phone terminal of the corresponding extension number. In other words, the control unit 103 call ** which is the most used during the extension. A voice message, such as a voice message, is read from the message storage unit 106, and the voice message is sent to a key phone terminal of the extension number which is switched after the voice call button is pressed. Accordingly, the voice output unit 116 of the key-phone terminal of the corresponding extension number receives the voice message from the message storage unit 106 through the host device connection unit 111 and transmits the voice message. The controller 103 transmits the voice message to the voice output unit of the extension phone number 120 of the extension number, and ends the control process according to the embodiment of the present invention.

As described above, the present invention can store the voice message most used when the extension is switched in the keyphone system, and can transmit the voice message when the extension is switched.
