Abstract

PURPOSE:To provide an extension number for each person by setting plural extension numbers to one extension telephone set. CONSTITUTION:When a program switch of an extension telephone set 2 is depressed and a function switch is depressed to enter a station key registration code and an extension number from a dial, the code and the number are stored and registered in a main storage device 15 from an extension control section 23 via a data transmission line 22, an extension circuit section 11 of a master set 1, and a master device control section 14. A function such as absence transfer and incoming reject is stored in the main storage device 15 acting like each extension number.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to automatic private branch exchanges.

0002

[Prior Art] Conventionally, even if one extension telephone had multiple users, only one extension number could be assigned, and incoming call processing was based on the attributes of the extension telephone, not the attributes of the individual. .

0003

However, the above conventional method has the following drawbacks. Firstly, even if a call comes in, you do not know who the call is going to until you answer it, and secondly, if you use call forwarding or call rejection functions, you have to get everyone's consent.

The present invention was made to improve the problems of the prior art described above, and even if there are multiple users of one extension telephone, it is possible for each individual to have a unique extension number. , the number is assigned to a key on the telephone (hereinafter referred to as the station key), and incoming calls appear on the station key, and by registering call forwarding or call rejection using the station key, the number can be exchanged according to the attributes of the individual's extension number. The purpose is to enable processing.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a station key assignment means for assigning an extension number for each individual to a key as a multi-station function, and an incoming call means for making an appearance on the station key when an incoming call is received. and station function registration means for registering call forwarding and call rejection in correspondence with extension numbers.

[0006]

[Function] With the above-described configuration, when the present invention receives a call, an incoming call display appears on the station key for each individual, and call forwarding and call rejection registered with a station key are effective only when the call arrives at that station key. It will not be given to the phone, but to the individual.
Even if one telephone is used by multiple people, it can be used without any inconvenience as if there were multiple extension telephones.

[0007]

Embodiments will be explained below based on the drawings.

FIG. 1 is a functional block diagram of an automatic private branch exchange according to an embodiment of the present invention. In FIG. 1, in a main device 1 that performs connections between a plurality of extension telephones and a central office line and various other controls, 11 is an extension circuit section for connecting extension telephones, and 12 is an extension circuit between an extension telephone and a central office line, or between extensions. 13 is a station line circuit section for connecting office lines; 14 is a main device control section for realizing a multi-station function; and 15 is a main device storage section. In addition, in the extension telephone 2, 21 is a voice transmission line;
2 is a data transmission section, and 23 is an extension control section that controls incoming call bells, lamps, etc. FIG. 2 is an external view showing an example of the extension telephone 2, in which 201 is a program switch, 202
is a function key, 203 is a call forwarding key, 204
205 is a dial key, 205 is a handset for making a call, and 206 is a call rejection key. Here, in order to reduce the number of keys, a case will be explained in which the function key used for receiving an outside call is also used as a station key for registering an individual's extension number.

[0009] Consisting of the above-mentioned components, the operation thereof will be explained next. First, when a personal extension number is registered in a certain function key 202 as a station key allocation means and used as a station key,
By turning on the program switch 201, the function as a function key is switched to a state where registration is possible, and a certain function key 202 is pressed, the call forwarding key 303 is pressed, and (instead of the call forwarding key 303, the station key registration code is may also be input using the dial key 204) If the extension number is input using the dial key 204, the data transmission line 22, extension circuit section 11, and
The information is stored in the main device storage section 15 via the main device control section 14 . After the registration is completed, by turning off the program switch 201, the function key 202 can be used as a station key from now on.

[0010] Next, when there is an incoming call,
An incoming call will be displayed on the corresponding station key, and you can answer the incoming call by picking up the handset or directly pressing that key.

[0011] Also, as a station function registration means, the registration operation of missed call forwarding is performed by pressing the station key 202 and
When the call forwarding registration special number and forwarding destination number are input using the dial key 204, they are stored in the main unit storage unit 15 through the main unit control unit 14, and the next call to that extension number will have the call forwarding function. Incoming calls to other station keys are as normal. You can also set call rejection in the same way as call forwarding. Here, we explained an example of using a function key as a station key, but
A dedicated station key may also be provided.

Next, the station key registration program of this embodiment will be explained based on the flowchart shown in FIG. In step 301, the input extension number is stored in the key/extension number correspondence memory shown in FIG. 5, and the process proceeds to step 302. In step 302, the telephone number of the extension is stored in the extension number management memory shown in FIG. Even when a call is forwarded or a call is rejected, it is stored in the extension management memory shown in FIG. 6. In FIG. 6, extension numbers 100 to 103 are set for telephone number 0, and extension number 104 is set for telephone number 1.

Next, the incoming call processing program of this embodiment will be explained based on the flowchart shown in FIG. When an extension call is made, the physical extension number is extracted from the extension management memory shown in FIG. 6 in step 401, and the process proceeds to step 402. In step 402, the presence or absence of call forwarding registration or call rejection registration is checked. If registered, call forwarding processing or call rejection processing is performed; if not registered, step 403
to move to. In step 403, the key position is extracted from the key/extension number correspondence memory shown in FIG. 5, and the process moves to step 404. In step 404, a call is received for that key.

As described above, in the present invention, a plurality of extension numbers can be assigned to one telephone as a multi-station function using the station key assignment means, the call receiving means, and the station function registration means.

[0015]

As described above, the present invention provides a station key assignment means for assigning an extension number for each individual to a key as a multi-station function, an incoming call means for making an appearance on the station key when an incoming call is received, and a station key assignment means for assigning an extension number for each individual to a key. It has a station function registration means for registering call forwarding and call rejection, and when a call arrives, an incoming call display appears on the station key for each individual, and call forwarding and call rejection registered with a station key are valid only when the station key receives a call. By configuring this, one extension telephone can be used like multiple telephones, and lines can be used effectively.
