Description

Description: TECHNICAL FIELD The present invention relates to a telephone having a function of automatically selecting and registering telephone numbers at the time of making or receiving a call.

[Conventional technology]

Conventionally, in a digital telephone having a function of automatically registering a telephone number at the time of making or receiving a call, the registration of the telephone number is carried out by transmitting the telephone number to the network at the time of making a call or the telephone of the other party transmitted from the network at the time of receiving a call. The control circuit automatically registers the number in the memory. And since there is a limit to the number of phone numbers that can be registered depending on the memory capacity, if the number of registered phone numbers exceeds the limit, delete the registered phone numbers from the oldest to the new one. Or I was not able to register new.

[Problems to be solved by the invention]

In the conventional telephones as described above, all telephone numbers transmitted to the network when making a call or all telephone numbers transmitted from the network when making a call are subject to registration. However, there is a problem that useful telephone numbers that have already been registered are deleted, unnecessary registration is performed in the memory, and useful telephone numbers cannot be registered.

The present invention has been made in order to solve such a problem, and an object thereof is to obtain a telephone in which an unnecessary telephone number is not registered in a memory due to a wrong pressing of a dial button or an incorrect telephone.

[Means for solving problems]

In the telephone according to the present invention, when the dial button is pressed at the time of outgoing call and the disconnection request is within a certain period of time, when the incoming call is received, the disconnection request from either the off-hook side or the called side is constant. When the time is less than the time, the telephone number is not registered in the memory.

[Action]

In the present invention, when the disconnection request from the pressing of the dial button at the time of outgoing call is less than a certain time and when the disconnection request from either the off-hook side or the called side at the time of incoming call is less than the certain time, The phone number is not registered in the memory.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of a telephone of the present invention. 1 is a handset, 2 is a dial button, 3 is a sounder, 4
Is a hook switch, 5 is an indicator, 6 is a calling circuit, 7 is a sending circuit, 8 is a receiving circuit, 9 is a timing circuit, 10 is a control circuit, and 11 is a memory.

Here, the operation will be described below, assuming that this telephone has a caller / callee number registration function, and a telephone number therefor is automatically registered in the memory 11 at the time of calling and receiving.

When the user makes an off-hook from the handset 1 and presses the dial button 2 when making a call, the clock circuit 9 starts clocking. At this time, if the user operates the dial button 2 by mistake, the user puts the handset 1 on hook and then operates the dial button 2 again. If the user does not make a mistake on the dial button 2, the user ends the call and goes on hook. At the same time as the on-hook, the control circuit 10 fetches the time information of the time circuit 9, and if the time measured by this is longer than a preset time, for example, 10 seconds or more, the operated telephone number is registered in the memory 11, and if it is within 10 seconds, the memory is stored. Do not register to 11. That is, if the dial button 2 is operated incorrectly, the time is kept within 10 seconds and the telephone number is not registered.

When a call is received and a connection request is transmitted from the network, the control circuit 10 is activated and the sounder 3 sounds, and at the same time, the clock circuit 9 starts clocking. Then, if the call is a wrong call, the caller and the callee request disconnection immediately after the incoming call is answered, and if it is not a call wrong, the disconnection request is made after a certain period of time. When the disconnection request is received, the timekeeping information of the timekeeping circuit 9 is fetched, and if the timekeeping time by this is longer than a preset time, for example, 20 seconds or more, the telephone number of the other party transmitted from the network is registered in the memory 11, and 20 seconds If it is within the range, it is not registered in the memory 11. That is, the telephone number is not registered when the call time is short such as a wrong call.

Therefore, only those useful as telephone numbers for recording the calling / called numbers are registered in the memory 11.

In the above embodiment, 10 seconds is used as a criterion for making a call and 20 seconds is used as a criterion for receiving a call, but these times can be freely changed.

〔The invention's effect〕

As described above, the telephone of the present invention selectively registers the telephone number by monitoring the call times at the time of making a call and the time of receiving a call, so that an unnecessary telephone number is not registered and the memory is effectively used. There is an effect that can be achieved.

Claims (1)

[Claims] 1. A telephone having a function of holding at least one or both of a telephone number transmitted to a network at the time of calling and a telephone number transmitted from the network at the time of receiving and automatically registering it in a memory provided therein. If the disconnection request from the pressing of the dial button is less than a certain time when making a call, and the disconnection request from either the calling side or the receiving side is a certain time or less when receiving a call, A telephone characterized in that the telephone number is not registered in the memory.
