Description

How to connect a phone to an extension phone that is called a pager on a simple electronic exchange

The present invention relates to a method for connecting a telephone to an extension telephone in which a call to a pager or pager has been made in a simple electronic exchange.

Conventionally, in a simple electronic exchange where a plurality of trunks are shared, when a caller waits for a call of a callee after calling a pager of a callee, when a callee calls, ) Or telling the caller to dial a phone call saying "Get a phaser caller" in a loud voice. Therefore, the process of connecting the telephone to the caller of the phaser is troublesome, and there are problems such as inconvenience to the people around him or irritation caused by the noise.

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and it is an object of the present invention to provide a simple electronic switching system in which an extension number of a telephone call in which a pager has been called is stored and an extension number of the telephone, And to easily connect to an extension telephone where a call is made.

In order to achieve the above object, a method for connecting a telephone to an extension telephone that is called a pager in a simple electronic exchange according to the present invention is characterized in that, when a pager is called by an extension telephone, A step of inputting a telephone number and an extension number of a caller, storing an extension number and a pager number input in the input step, and a step of, when a call is received from a callee to find a caller who made a pager call, Pressing a specific key, and connecting to the extension telephone calling the pager in the simple electronic exchange.

The method according to the present invention further includes a step of determining whether or not there is one pager-called extension following the step of pressing the specific key, and a step of determining whether one pager-called extension is one or not Determining whether or not the extension number is 2 or more; if the number is 2 or more, displaying an extension paged in the connection step before the connection in the connection step and pressing an extension number of the list; Determining whether or not there is a paging-called extension, if the number is not equal to or greater than 2 in the determining step, and automatically notifying the calling party of the pager call when there is no called extension.

These and other objects and advantages of the present invention will become more apparent from the detailed description of the embodiments of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 to 3.

FIG. 1 is a block diagram illustrating the configuration of a typical keyphone system and the internal configuration of a main component. The key telephone system of FIG. 1 is composed of a key telephone system 10, which is a simple electronic telephone exchange, a key telephone 20 connected to the key telephone system 10, and a general telephone 30. The internal configuration of the keyphone system 10 is configured to receive signals transmitted from a CO line interface board 11 for receiving a signal transmitted from a telephone station and to process and control signals transmitted from the CO line interface board 11, A central processing / switching device 12 for switching to the corresponding telephone among the installed extension telephones 20 and 30 and an extension interface board 13 for transmitting the signal to the extension telephones 20 and 30. The internal structure of the key telephone 20 includes an extension line interface circuit 21 for receiving a signal from the extension interface board 13, a microprocessor 22 for processing the received signal, a liquid crystal display A light emitting diode (hereinafter referred to as LED) / a keyboard circuit section 23 and a handset / speaker / microphone circuit section 24.

In the key telephone system configured as above, a process in which a caller calls a called party's pager to an extension phone 20, 30 and then receives a call from a called party will be described with reference to FIGS. 2 and 3.

FIG. 2 is a flow chart for explaining the operation of the key telephone system 10 shown in FIG. 1 when a caller calls a called party's pager with an extension telephone according to the method of the present invention. FIG. FIG. 5 is a flowchart illustrating a process of notifying a caller of a call from a callee to an extension pager-called by the keyphone system 10. FIG.

First, in order for the caller to call the pager of the called party using any of the extension telephones 20 and 30, the handset 24 of the extension telephones 20 and 30 is first picked up (step 1) as shown in FIG. 2, Press the number key of the telephone corresponding to the callee's pager number or enter dialing to enter the callee's pager number and then enter the callee's telephone number (step 2). Subsequently, in step 3, the keyphone system 10 determines whether the person who called the extension telephone 20, 30 is making a normal call or a pager call. At this time, when the first digit of the number input to the keyphone system 10 is, for example, 012 or 015, it is recognized as a pager call. If the pager call is determined in step 4, the extension number and the pager call number are recorded and stored in the pager call list table (not shown) in the keyphone system 10.

Next, when a call is frequently made to the caller from the callee (step 1), as shown in FIG. 3, if the call is a call for a call with the caller, the call is notified in step 2 (Not shown) of the key telephone system 11D.

If there is only one extension to which a pager call has been previously performed (step 3), the ring is automatically switched to the extension number of the telephone in which the pager call was made in step 4. As a result, the ring tone of the telephone number of the called extension will be sounded and the ring tone of other telephone will not be sounded. At this time, if the called extension is busy, the extension becomes a Hold and an extension call is made, and the caller informs the caller that the call is received. In this case, the LCD or the LED of the key telephone 20 may be used to notify the caller that a response call has been received from the callee.

(Step 5), the keyphone system 10 reads out the pager call list stored in Step 4 of the second figure from the pager call list table and stores the pager call list of the key phone telephone 20 Display it on the LCD and press the extension number of the list (step 6). At this time, the pager call list of the called extension is displayed on the LCD, for example, as follows.

1 0127135114

2 0128223950

3 0121112222

4 0155555654

5 0155559735

Here, the first number is the extension number, and the next three digits, 012 or 015, is the service number indicating the pager call, and the remaining numbers are the caller's pager number.

Subsequently, after the execution of Step 6, the process proceeds to Step 4, and the ring is automatically switched to the extension number of the telephone in which the pager has been called. As a result, the ring tone of the telephone number of the called extension number rings. At this time, if the called extension is busy, the extension becomes a Hold and an extension call is made, and the caller informs the caller that the call is received.

However, if there is no extension to which a pager call has been made (step 7), it is indicated on the LCD or LED that there is no extension to which the pager has been paged and the caller has not been called to the pager That is, by using the automatic voice response function, or it can be manually notified by the person who received the call manually.

According to the method of the present invention as described above, the extension number of the telephone in which the pager has been called is stored in the simple electronic exchange, and when a telephone call to find the caller is received, one button is selected in accordance with the display of the extension number of the telephone You can automatically notify the extension phone through the ring or speakerphone when the call is made. If there is no extension, it indicates that there is no extension and it is not called. To the other party.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be determined by the claims.
