Abstract

PURPOSE:To control the individual level of a user and to execute call origination with high efficiency by regulating the call origination by the users of telephone sets. CONSTITUTION:A memory part 4 is provided to store an ID code for each user and number for call origination regulation corresponding to this ID code. When the user inputs the ID code and the number of a called party, a control part 5 collates this ID code with the ID code which is stored in the memory part 4. When the ID code corresponds to the stored ID code, the number for call origination regulation corresponding to the ID code is retrieved. When the call origination regulation is executed to the number of the called party, the call origination is executed and when the call origination regulation is not executed to the number, a call is originated. Accordingly, the individual level of the user can be controlled and when the user is the called party, tor which the call origination is not regulated, the call can be origination from an arbitrary telephone set. Thus, the call origination can be executed with the high efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a button telephone device that is capable of restricting outgoing calls.

2. Description of the Related Art Conventionally, key telephone devices have been known that restrict calls from telephone numbers other than specific telephone numbers.

In any case, this conventional button telephone device is configured to restrict outgoing calls to telephone numbers other than a specific telephone number for each telephone. That is, for example, telephone A cannot make calls to anything other than internal numbers, telephone B can make calls to both internal and external numbers, but cannot make calls outside the local area, and telephone C cannot make outside calls. Although it is possible, there are some areas where calls are not possible, and a call restriction number is stored in the memory section for each telephone. Further, for example, a telephone set does not store a call restriction number in its memory so that calls can be made in any of the above cases. Then, when the user dials the destination number using the dial keys, the control unit searches the memory unit and determines whether or not the telephone number is restricted from making outgoing calls, and if it is determined that the number is restricted from making outgoing calls The system restricts outgoing calls, and if it is determined that the number is not restricted from outgoing calls, that phone number is sent out.

Problems to be Solved by the Invention However, in the above-mentioned conventional button telephone device, since it is the telephone itself that can restrict outgoing calls, anyone can make calls to a desired area by using a telephone that is not restricted from making outgoing calls. It is possible to make calls to a desired area, and it is difficult to completely restrict calls for each user. On the contrary, when a user wants to make a call to a desired area, he or she must use a designated telephone set that is not subject to call restrictions for that area, which is inconvenient.

The present invention solves such conventional problems, and makes it possible to restrict outgoing calls for each telephone user, and thus to manage each user at an individual level.
Another object of the present invention is to provide a button telephone device that allows the user to make calls using any telephone if the user is not restricted from making calls, thereby increasing the efficiency of outgoing calls. That is.

Means for Solving the Problems In order to achieve the above object, the present invention provides (7)
A memory section that stores an ID code and a call restriction number corresponding to this ID code, and an ID that stores an ID code and a destination number input by the user in the memory section.
The device is equipped with a control unit that checks the code and the call restriction number and restricts dialing if the call is restricted.

Effects The present invention has the following effects due to the above structure. That is, when the user inputs the ID code and the other party's number, the control unit compares this ID code with the ID code stored in the memory unit, and if they match,
It is possible to search for the call restriction number corresponding to the ID code, restrict calls if the number to which the other party is calling is a number that is restricted, and allow calls to be made if the number is not restricted. You can restrict outgoing calls for each user.

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

FIG. 1 is a schematic block diagram showing a key telephone device according to an embodiment of the present invention. In Figure 1, l is a dial key for inputting an ID code and dialing the other party's telephone number, etc. 2 is an ID input using dial key 1
Key manual reading unit for reading codes, destination numbers, etc.
Reference numeral 3 indicates a call restriction means into which the destination number read by the key manual reading unit 2 is input, and is capable of regulating outgoing calls from this destination number; 4 indicates an ID code for each user of this device and an ID code for this ID code; This is a memory unit that stores the corresponding call restriction number. For example, user A cannot make calls to anything other than extension numbers, and user B can make calls to both extension and outside numbers, but cannot make calls outside the city. Yes, user C is able to make calls outside the city, but there are areas where calls are not possible. For example, the user can make a call in any of the above cases, that is, the call restriction number corresponding to the user's ID code is not stored. Reference numeral 5 denotes a control unit consisting of a CPU, which compares the ID code and destination number read by the key manual reading unit 2 with the ID code and call restriction number stored in the memory unit 4, and if they match. The transmission restriction means 3 is operated to restrict transmission, and if they do not match, the transmission restriction means 3 is activated.
control so that it does not operate. In this device, an ID code is assigned to each user, and when making a call, the user must first dial the ID code using the dial key 1 and then dial the destination number before making a call.

Next, the operation of the above embodiment will be explained with reference to the flowchart shown in FIG.

When the user first inputs an ID code using the dial key 1 (step a), this ID code is read by the key reading unit 2 (step b), and the information is added to the control unit 5. The control unit 5 searches whether the ID card is registered in the memory unit 4 or not (step c).
, if it is not registered, the control unit 5 determines that the call is not possible, and controls the call restriction means 3 so that the -cut call is not made (step e). On the other hand, if the ID code is registered in the memory section 4, the control section 5 corresponds to the ID code the other party's number dialed following the ID code using the dial key 1 and added via the key reading section 2. If the number is a restricted number, the calling restriction means 3 is controlled to restrict calling, and the destination number is not sent, and the number that is not restricted is checked. If so, the call restriction means 3 is controlled to be in a callable state and the destination number is sent. (Step f). .

In this way, according to the above embodiment, the user can input the ID code assigned to him/herself, followed by the destination number, and make a call only if the destination number is not restricted from making calls. , it is possible to manage calling areas for each user and easily manage telephone charges, etc. Further, as described above, the user can make a call by inputting the ID code assigned to him/herself, so that the user can make a call using any telephone connected to this device.

Note that the call restriction number itself may be a number subject to call restriction, or the number excluding the number may be a number subject to call restriction.

Effects of the Invention As described above, according to the present invention, when a user inputs an ID code and a destination number, the control unit compares this ID code with the ID code stored in the memory unit and takes appropriate action. If the number of the other party is a number that is restricted from calling, it is possible to restrict calls, and if the number is not a number that is restricted, it is possible to make calls. . In this way, it is possible to restrict outgoing calls for each telephone user, and therefore, it is possible to manage each user on an individual level. , it is possible to make a call using any telephone, and it is possible to improve the efficiency of the call.
