Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ISDN telephone having a function of preventing an erroneous call when a call is made.

[0002]

2. Description of the Related Art Usually, the ratio of making a first call to a destination is relatively low, and there are many cases where a destination that has been called has been dialed. By the way, it is often the case that one person accidentally makes a mistake and makes a mistake, or makes a mistake in the area code. It has been desired to realize a telephone that can recognize such an error in dial operation.

[0003]

On the other hand, in a telephone using ISDN which is a high-speed data transfer line, the receiving party can know the telephone number of the called party.
By storing this as the registration number, it is possible to collate the telephone number with the registration number when making a call to the other party next time. The present invention has been made in the background described above. The incoming call destination telephone number and the incoming call destination telephone number from the own station are stored as registration numbers, and this registration number and the dialed telephone number are stored. An object of the present invention is to provide an ISDN telephone having an erroneous outgoing call prevention function for automatically checking the user and notifying the user when a part of the telephone number is mistakenly dialed and for preventing a wrong telephone call. And

[0004]

In order to achieve the above object, the present invention provides a memory for storing the telephone number of the other party included in a call setting message of the ISDN communication protocol at the time of incoming and outgoing calls, and a telephone at the time of outgoing call. A check means for checking whether the number is in the registration number already stored in the memory, and if not, a determining means for checking whether or not there is a part of the registration number that is different from the telephone number at the time of calling; As a result of the determination of
If there is a part of the registered number that is different from the telephone number at the time of calling, it is considered that there is an error in the call input, and warning means for issuing a warning and the warning by the warning means are issued.
Nevertheless, if the call is continued, the new telephone number will be updated.
It is also an ISDN telephone having an erroneous call prevention function, which is provided with registration control means for registering in the memory .

[0005]

According to the above construction, the telephone number of the other party is stored in the memory at the time of incoming and outgoing, and the discrimination means determines whether or not the telephone number at the time of calling is among the registration numbers already stored in the memory. If not, check if there is a number in the registration number that is partially different from the telephone number at the time of calling. As a result, if there is a part of the registered number that differs from the telephone number at the time of calling, it is considered that there is an error in calling input,
A warning is issued. In addition, even if the call input is partly different from the telephone number in the registration number, if it is not an error,
By ignoring the warning, a normal call can be made. And in that case, please add the telephone number newly
Register in memory.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An ISDN telephone having an erroneous call preventing function according to an embodiment of the present invention will be described with reference to FIG.
This telephone is a digital high-speed data transfer line I
It has a layer 1 processing unit 11, a layer 2 processing unit 12, a layer 3 processing unit 13 connected to the SDN line 10 and a management unit 14 for controlling the system. Further, the system control unit 15 (discriminating means) for checking the number and I
A memory unit 16 for storing the telephone number of the other party included in the call setting message of the SDN communication protocol at the time of incoming and outgoing calls, and an interface unit 17 are provided. The interface unit 17 has a keyboard 18 for inputting numbers.
And alarm 19 to give a warning when the number is wrong
(Warning means) is connected.

In the above structure, the signal received through the ISDN line 10 is sequentially processed by the layer 1 processing unit 11, the layer 2 processing unit 12, and the layer 3 processing unit 13, and the signal is received via the management unit 14. The effect is transmitted to the interface unit 17. At this time, the telephone number of the other party transmitted as a call setting message from the layer 3 processing unit 13 is passed through the system control unit 15 to the memory unit 1
Take in 6. Similarly, when making a call, the keyboard 18
The destination telephone number input via the interface unit 17 is loaded into the memory unit 16. System control unit 1
If the input number of the outgoing call is highly likely to be incorrect based on the telephone number stored in the memory unit 16, the device 5 issues a warning by the alarm 19 via the interface unit 17.

The procedure of registration processing upon receipt of an incoming call by the management unit 14 and the system control unit 15 will be described with reference to the flowchart of FIG. The management unit 14 and the system control unit 15 extract the calling number from the call setting message of the layer 3 processing unit 13 (# 1). Next, it is checked whether or not this number is already registered in the memory unit 16 (# 2). If it is not a registered number, it is registered in the memory unit 16 (# 3), and if it is a registered number. , And ends the process.

Next, the operation procedure at the time of making a call will be described with reference to the flowchart of FIG. After waiting for the input of the calling number (# 5), it is checked whether or not the same number exists in the registration numbers stored in the memory section 16 (# 6). If there is the same number, this process ends, and if there is no same number, then it is checked whether or not the registration number has a one-character difference or a slight difference (# 7). If this is not the case, this calling number is considered to be the first number, so the number is registered (# 10). If there is, there is a high possibility of an input error, so it is regarded as an input error and the alarm 18 is driven to issue a warning (# 8). If the caller becomes aware of the mistake with this alert, they can enter the phone number again.
Further, when the caller ignores the warning despite the warning being issued (# 9) and continues calling, the number is newly registered as a correct number (# 10). The time when the warning is issued may be set appropriately.

As described above, it is the first time for the other party to check whether or not there is an input error by checking whether or not there is a difference between the registered number and the registered number. According to the background, the ratio of making calls to is relatively low, and there are many cases where dialing is made to a destination that has been called. In addition, since a warning is issued when it is considered that there is a high possibility of making an error as described above, it is possible to prevent the user from accidentally pressing the telephone number key and making a mistake.

[0011]

As described above, according to the present invention, the ISDN
In the telephone, the incoming and outgoing telephone numbers are stored in the memory, and at the time of making a call, it is checked whether there is a part of the stored registration number that is different from the telephone number at the time of making a call,
If there is a part of the registered number that is different from the telephone number at the time of calling, it is considered that there is an error in the call input and a warning is issued, so make a second or subsequent call. At times, it is possible to prevent a wrong call due to an inadvertent mistake in dial operation. Also, even if a warning is issued,
If the user ignores it and continues the call, the telephone number
Is regarded as the correct one and is newly registered in the memory.
A new phone number that is considered correct is automatically registered.
It is necessary to perform key input operation only for registration each time
It is free from the hassle.
