Abstract

PURPOSE:To recognize the caller number from a telephone set at a visiting place by storing a caller number of an opposite side to a memory. CONSTITUTION:When an incoming call comes while a user of a telephone set selected into the automatic reply mode visits somewhere, caller number information set via an ISDN line through a signal channel D is separated by a line I/F circuit 2 and stored in an outgoing ID storage memory 24. On the other hand, when the user makes a call to the telephone set from a telephone set at a visiting place and dials a prescribed personal identification number or the like, the dial number is decoded by a central processing unit 20. When the dial number is correct, the central processing unit 20 reads the caller number in the memory 24 and sends it via a voice synthesis section 23.

[Problems to be Solved by the Invention] Conventional telephones are configured as described above, and caller numbers of missed calls are stored. Therefore, you can know the other party by displaying it on the LCD.

However, in order to perform such operations, it is necessary to directly operate the telephone, and it is necessary to go home once.

Therefore, when going out for a long period of time or in case of an emergency, the user cannot respond well and cannot fully perform its functions.

This invention was made in view of the above points, and it is possible to easily check the presence or absence of missed calls from a telephone outside the home, that is, from a telephone located at a remote location, and if there are missed calls, the presence or absence of missed calls can be easily checked from a telephone located at a remote location. The object of the present invention is to provide a digital telephone that can tell the calling party's number by voice.

[Means for Solving the Problems] One aspect of the present invention provides a memory means for storing the calling party's number of the called party, a recording and reproducing means for reproducing and outputting prerecorded voice, and a predetermined voice received through an information channel. receiver means for decoding the code of the memory means; further comprising a missed call control means for controlling these means; and a missed call control means for controlling these means; The present invention is characterized in that it includes a called number notification means that outputs a signal.

[Function] According to the present invention, when there is a missed call, the missed call control means automatically answers the call, drives the recording and reproducing means, and furthermore, the calling party number of the other party is stored in the memory means.

Then, when decoding is performed by the receiver means, the called number notification means outputs the calling party number of the called party who received the call in the absence of the caller as a voice signal.

[Example 1] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings. Note that the same reference numerals are used for the same components as in the prior art described above.
