Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an extension call restriction device used in digital electronic exchanges, key telephone main units, and the like.

Conventional technology FIG. 2 shows the configuration of a conventional extension call restriction device.

In FIG. 2, 1 is a multi-function telephone with a button that can register an extension calling function, 2 is a call path,
3 is a central control unit that controls the telephone 1 and the call path 2, and includes a function registration area 4 that corresponds to the buttons on the telephone 1, and a registration area that realizes the extension calling function when the button to which the extension calling function is registered is pressed. It has a function access means 5 and an incoming call restriction extension number storage area 6 for storing an extension number for which extension incoming call restriction is to be performed.

Next, the operation of the above conventional example will be explained.

As is well known, when a user dials the extension number of a desired telephone set 1 or presses a button in which a function to call a specified extension is registered, the central controller 3 uses the registered function access means 5 to call the telephone line 2. Call the other party's extension via . At this time, if the extension number registered in the incoming call restriction extension number storage area 6 of the central control device 3 matches the extension number to be called, the central control device 3 restricts incoming calls.

In this way, even with the conventional extension call restriction device, incoming calls can be restricted by registering the extension number to be restricted in the call restriction extension number storage area 6 of the central control unit 3.

Problems to be Solved by the Invention However, in the above-mentioned conventional extension call restriction device, when an extension number is registered in the incoming call restriction extension number storage area 6 of the central control device 3, when dialed, the button to which the extension calling function is registered is activated. In either case, there was a problem in that incoming calls were restricted when the button was pressed.

The present invention solves these conventional problems, and even if a telephone is restricted from receiving calls, the extension will only be called when a button is pressed on a specific terminal (telephone) that is registered with the extension calling function. It is an object of the present invention to provide an extension call restriction device that can receive calls and prevent calls due to incorrect dialing.

Means for Solving the Problems In order to achieve the above object, the present invention provides function registration means corresponding to each button on the terminal, and realizes an extension calling function when a button in which the extension calling function is registered is pressed. A registration function access means for controlling an extension call, a means for storing an extension number for restricting incoming calls, and an internal call function for determining whether an extension call is called by dialing or by pressing a button to which the extension call function is registered. The apparatus includes a method determining means and a means for storing an extension number that permits incoming calls only when an extension call is made by pressing a button in which an extension call function is registered.

Therefore, according to the present invention, when calling an extension, it is determined whether the extension is called by dialing or by pressing a button in which the extension calling function is registered. However, it is possible to restrict incoming calls, and to allow incoming calls to an extension called by pressing a button in which the extension calling function is registered.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, 1 is a multifunctional telephone (terminal) with a button that can register an extension calling function, 2 is a call path, and 3 is a central control unit that controls the telephone 1 and the call path 2. Function registration area 4 corresponding to the buttons on the phone
, a registered function access means 5 that realizes the extension calling function when a button in which the extension calling function is registered is pressed in a so-called one-touch operation, and an incoming call restriction extension number storage area 6 that stores the extension number for which the extension call restriction is to be performed. , an extension calling method determining means 7 for determining whether the extension is called by a dial operation or by a so-called one-touch operation of the above-mentioned button; and a specific incoming call that stores an extension number that allows incoming calls only when the extension is called by the one-touch operation. It has a restriction release extension number storage area 8.

Next, the operation of the above embodiment will be explained.

When an extension is registered in the incoming call restriction extension number storage area 6 and is restricted from receiving calls, when the extension is called by a so-called one-touch operation of pressing the button on the telephone 1 to which the function to call the extension is registered, the extension calling method is changed. The determining means 7 determines that it is a one-touch extension call,
It is checked whether an extension number that matches the extension number in question exists in the specific incoming call restriction release extension number storage area 8.

If the extension exists, the registered function access means 5 calls the other party's extension via the communication path 2, and the call reception state is established.If the extension does not exist, the reception is restricted. On the other hand, in the telephone l,
When an extension registered in the incoming call restricted extension number storage area 6 is called by a dial operation, the extension calling method determining means 7 determines that the call is due to a dial operation and restricts the incoming call.

In this way, according to the above embodiment, the incoming call restriction can be canceled only when an extension is called by one-touch operation of a button in which the function of calling an inside is registered, and the extension can be called only from a specific telephone 1. has advantages. Further, according to the above-mentioned embodiment, it is possible to restrict calls to extensions due to dialing operations, so there is an advantage that incoming calls due to incorrect dialing can be prevented.

Effects of the Invention As described above, according to the present invention, when an extension call is made, it is determined whether the extension call is made by dialing or by pressing a button in which the extension calling function is registered, so that the extension call can be made by dialing. It is possible to restrict incoming calls from certain terminals (telephones), and allow calls to be received by pressing a button on which the extension calling function is registered. It is also possible to prevent incoming calls due to incorrect dialing.
