27 is a hook switch detection circuit for detecting the on / off state of the hook switch 26; 28 is an incoming call selection key (second calling means) for setting whether or not a ringing tone is emitted unconditionally when an incoming call signal is received; Is a handset for inputting and outputting voice for a call, 30 is a call circuit for handling voice signals,
Reference numeral 31 denotes a codec for converting an audio signal from analog to digital.

Reference numeral 32 denotes a network interface circuit (caller number recognition means) for decomposing an incoming signal into a message;
3 determines whether the calling party number is registered in the memory 25 when the message decomposed by the network interface circuit 32 includes the calling party number, and makes the determination result and the incoming call selection. A signal control circuit (caller number recognition means, determination means, first calling means, second calling means) for controlling the display control circuit 22 and the ringing tone control circuit 24 in accordance with the setting state of the key 28. FIG. 2 is a flowchart showing the operation of the digital telephone according to the first embodiment of the present invention.

Next, the operation will be described. First, when an incoming signal is transmitted from another telephone via the public telephone network, the network interface circuit 32 receives the incoming signal and breaks it down into a message (step ST1). Output to

When the message is output from the network interface circuit 32, the signal control circuit 33 recognizes the caller number if the message contains the caller number (step ST2). ), It is determined whether or not the calling number is registered in the memory 25 (step ST3).

If the calling number is registered in the memory 25, the signal control circuit 33 sends a control signal indicating that fact to the display control circuit 22 and the ringing tone control circuit 2.
4 and a ringing tone is output from the speaker 23 (step ST5), and the calling party number is displayed on the display 21 (step ST6).

On the other hand, if the caller number is not registered in the memory 25, it is determined whether or not the incoming call selection key 28 is set to a mode for unconditionally generating a ring tone when an incoming call signal is received. (Step ST4). If the mode is set to unconditionally generate a ringing tone when an incoming signal is received (this mode is set when it is necessary to receive an incoming call from an analog telephone, for example), the calling party number is set. Is registered in the memory 25, a ringing tone is output from the speaker 23 (step ST5), and the calling party number is displayed on the display 21 (step ST6).

Thus, even when an incoming call is received from an analog telephone having no caller number, a ringing tone is output from the speaker 23, and a telephone call with the analog telephone is enabled. However, even in this case, when a call is received from a digital telephone whose caller number is not registered in the memory 25, the caller number is displayed on the display 21 (step ST6). Is somewhat bothered by the ringing tone, but it can be determined whether it is a malicious call such as a mischief. Incidentally, since the mode setting status is displayed on the display 21 or the like, the user can easily recognize the current mode setting status.

On the other hand, when a mode for unconditionally generating a ringing tone when an incoming signal is received is not set (this mode is not limited to a digital telephone, and a case where a call for a malicious call from an analog telephone is to be avoided) The ringing tone is not output from the speaker 23, the calling party number is displayed on the display 21 (step ST6), and a series of processing is terminated.

Thus, if the calling party number is not registered in the memory 25, the ringing tone is not output from the speaker 23, so that it is possible to avoid a call for a malicious call such as a mischief, and to prevent a malicious call such as a mischief. The effect of avoiding the mental pain suffered by the user due to the ringing sound of the telephone is achieved.

[0019]

As described above, according to the present invention , when the mode setting means is set to the mode in which the ringing tone is emitted unconditionally, the ringing tone is emitted regardless of the determination result of the determining means.
In addition, since the configuration is such that the caller number is displayed, there is an effect that a convenient telephone can be obtained, which can permit an incoming call from an analog telephone whose call signal does not include the caller number as necessary. Also, since the calling number is displayed as well as the ringing tone, the calling number is not registered even when the mode is set to unconditionally emit the ringing tone when an incoming signal is received. When an incoming call is received from a digital telephone, the user is somewhat bothered by the ringing tone, but has the effect of being able to determine whether or not the call is a malicious call such as a mischief. Further, when the judgment result of the judging means indicates that the calling number is not registered ,
If the mode is not set to ring unconditionally , the phone will not ring and will also display the caller ID.
If the calling number is not registered, the ringing tone is not output, and as a result, it is possible to avoid a call for a malicious call such as a mischief, and to make a ring tone for a telephone accompanying a malicious call such as a mischief. You can avoid the psychological distress user incurred by, and the effect of the caller can be identified.
