Field of the Invention The present invention relates to a private branch exchange and a recording medium on which a program used for the private branch exchange is recorded, and more particularly to a calling system when one terminal user uses a plurality of terminal lines. is there.

[0002]

2. Description of the Related Art In a conventional electronic private branch exchange, when one terminal user uses a line of a plurality of terminals, for example, when a private cordless telephone is used in addition to a telephone set on a desk, a terminal is used. If the user calls the telephone set at the desk after leaving the desk, the user cannot answer. In order to answer with the telephone set at the desk when leaving the desk, call forwarding or unanswered transmission can be set to the cordless telephone number. In addition, when there are three or more telephones or lines, for example, when using a multi-function telephone and a cordless telephone having a plurality of lines, and when using a PC telephone, the user who calls the telephone is called. Respond to If the user has set functions such as call forwarding, unanswered forwarding, and the like, the terminal at the forwarding destination can respond.

According to a key telephone apparatus disclosed in Japanese Patent Application Laid-Open No. 2-90796, a cordless telephone is connected as a standard telephone to a key telephone main apparatus, and when a specific key telephone is called, the cordless telephone is simultaneously called and used.

Embodiments of the present invention will now be described with reference to the drawings. Referring to FIG. 1, an embodiment of the present invention includes a switch 1 of a private branch exchange, a central processing unit 4 for controlling the switch 1, a number storage device 6 for storing a unique number and a line number of a terminal user in association with each other. The central processing unit 4 reads out the terminal user's unique number from the number storage device 6 and reads out the line's unique number associated with the terminal user's unique number.

There are 21 to 24 telephones that can be used by the terminal user. 21 is a normal extension telephone, 22 is a multi-function telephone accommodating a plurality of lines 221 and 222, 2
Reference numeral 3 denotes a telephone using a personal computer (PC) (hereinafter referred to as PC telephone), and reference numeral 24 denotes a cordless telephone for business use. Also,
Receiving device 25 of cordless telephone 24, telephone 2 of terminal
A specific number receiving device 11 for receiving a specific line number to be dialed by telephones 1 to 24, and an external line 3 for receiving a call to telephones 21 to 24
There is provided a trunk 12 for relaying a call from the. The switch 21 has the above-mentioned 21 to 23, 25, 11, 12,.
4 are connected.

Further, the central processing unit 4 controls an operation described later according to a program recorded on the recording medium 41. As the recording medium 41, a semiconductor memory, an optical disk, a magneto-optical disk, a magnetic recording medium, or the like can be used.

Next, the operation of the embodiment of the present invention will be described.
This will be described in detail with reference to the block diagram of FIG. 1 and an example of memory allocation of the number storage device of FIG. Outside line 3 to line 222
When making a call, the trunk 12 receives the number of the line 222 and sends it to the central processing unit 4. The central processing unit 4 having received the number reads the user number of this line,
The terminal user number reading device 51 is started. The terminal user number reading device 51 is connected to the line storage 22 from the number storage device 6.
Read the user number of No. 2. Set the number of the line 222 to 345
6, the line number memory 62 in the memory allocation diagram of FIG.
Is stored in the user number memory 61 corresponding to the line number 3456.
Is read.

The central processing unit 4 that has read the terminal user number activates the line number reading device 52. The line number reading device 52 reads all line numbers corresponding to the user number from the number storage device 6. Referring to FIG. 2, the user number 1234 is found from the user number memory 61,
The line number corresponding to the number is read from the line number memory 62. In this case, 2345, 3456, 456
7, 5678, and 6789 are line numbers.

Further, the central processing unit 4 reads out, through the line number reading device 52, whether or not each line can be called from the call storage memory 63 provided corresponding to the user number from the number storage device 6. Referring to FIG. 2, line number 23
Since the memory of all the call prohibition memories 63 of 45, 3456, 4567, 5678, and 6789 is "0", all the lines can be called. When the memory of the call prohibition memory 63 is “1”, the call is prohibited.

The central processing unit 4 which has received the line numbers and the call prohibition information transmits a call signal to all the lines corresponding to all the received line numbers, and starts monitoring the responses of all the lines. If the call prohibition information is "1"
Is excluded from the line to be called. However, response monitoring is performed. The central processing unit 4, which has read out the line number and the callability, sends a call signal to all the lines that can be called and starts monitoring the responses of all the lines that can respond. In the case of the embodiment, the extension telephone 2
1. A calling signal is transmitted to all of the multi-function telephone 22 (lines 221 and 222), the PC telephone 23, and the cordless telephone 24.

After confirming the call, the user answers with an arbitrary telephone among the telephones 21 to 24 used by the user. In the case of this example, when a response is made by the cordless telephone 24, the central processing unit 4 connects the trunk 12 and the cordless telephone 24 through the switch 1. After confirming the response, the central processing unit 4 cancels the calling signal transmission and the response monitoring for all the lines that are monitoring the response.

When one of the telephones 21 to 24 dials a specific one of the line numbers of the other telephones, the specific number receiving device 11 detects this and notifies the central processing unit 4 of the dialing. In response, the central processing unit 4 calls the telephone of the specific line number and prohibits the calling of the other telephones.

As a result, the incoming call is displayed only on the telephone having the specific line number, so that it is possible to prevent the incoming call from being displayed on a plurality of telephones at the same time. At this time, by monitoring the response of the telephone that has not been called, it is possible to respond from the telephone that has not been called. These functions are convenient when, for example, a telephone that is not called is installed near a telephone of a specific line number on which the incoming call display is made.

Further, the unique number of the line used by the number storage device is stored in association with the unique number of the terminal user, and when there is an incoming call on the line of the present device, the storage device is stored in association with the unique number of this line. The unique number of the terminal user is read out, and the lines of the unique numbers of all the lines related to this unique number are called. Thus, if the terminal user using a plurality of lines sets the unanswered transfer setting for only one arbitrary line when setting the unanswered transfer, all the lines are automatically set to the unanswered transfer setting. . Therefore, there is no need to remember which line has been set for unanswered transfer and call forwarding.

[0033]

As described above, according to the present invention,
A storage means is provided for storing the line number of the line to be used in association with the user number of the terminal user. When an incoming call is received on the line, the exchange stores the use number stored in association with the line number of this line from the storage means. By reading out the user number and calling the lines of all the line numbers related to this user number, if one terminal user uses a plurality of terminals and lines, the call is received on any one line. In this case, all the lines can be called at the same time, so that the terminal user can answer the desired line at that time without being aware of which terminal or line has arrived. Also, by setting the unanswered transfer to any one line, this function can be enabled without setting the unanswered transfer to all available lines. This eliminates the need to make a troublesome determination as to whether response transfer or call forwarding is set.

Further, by monitoring the responses of the lines other than the called line and stopping the calls of the lines other than the line that has responded, it is possible to respond from any terminal having a common user number. Also, by storing the call prohibition information in the storage means, it is possible to prohibit the call of the line of the specific line number.

Further, by detecting a call of a specific line number and calling that line, only a specific terminal can be called. Further, by monitoring the response of the other line when calling the specific terminal and stopping the call of the line other than the line that responded,
A response can be made from a terminal other than a specific terminal.
