In such a system, the information communication message 13 including the calling subscriber number is transmitted from the # 2 telephone terminal 12 to the # 1 telephone terminal 12.

[0006]

In the conventional communication system, as described with reference to FIG. 6, the subscriber terminal cannot identify the caller. Therefore, only the process of sending the same message to any caller and recording the message from the caller thereafter is performed. However, some callers may not need to record, and the answering machine function, which can perform the same processing for all callers, is also inconvenient.

The present invention has been made in view of the above problems, and an object thereof is to provide a designated call answering machine system capable of improving the answering machine function.

The same parts as those in FIG. 1 are designated by the same reference numerals. In the figure, the sender number accumulating section 25 comprises a sender number storage area 25a, a message number storage area 25b and a recording means activation flag 25c. The caller number accumulating unit 25 stores a caller number from the registration unit 27 in advance.
Register the message number and recording activation flag.

For the activation flag, the activation flag 25c is set to "0" for the calling subscriber who does not need to record the voice message from the calling subscriber, and the voice message needs to be recorded. Active flag 2 for a subscriber
5c is set to "1". Then, only voice messages from important subscribers can be recorded.

The voice message storage unit 26 stores a voice message corresponding to the message number of the caller number storage unit 25. This voice message is also registered in advance from the handset or the like under the control of the registration unit 27. deep. Two
Reference numeral 9 is a recording unit for recording a voice message from the calling subscriber. A subscriber terminal 40 is composed of these components. Other configurations are the same as those in FIG. The operation of the circuit thus configured will be described below. (At the time of registration) At the time of registration, the subscriber writes, from the registration unit 27, a sender number related to the sender, a message number for the sender, and an activation flag. Here, the active flag is set to "0" for subscribers who do not need to record messages from the other party subscriber, and active for subscribers who need to record messages from the other party subscriber. The flag is set to "1". In addition, a voice message is written in the voice message storage unit 26 from the handset for each message number. (During operation) When the incoming call from the calling subscriber is received, the response delay unit 23 controls the control unit 24 with the absence signal as a trigger when the off-hook is not performed even after a certain period of time. Notify the section 24. Control unit 24
Upon receiving this absence signal, starts the answering machine registration operation at the time of absence.

First, the caller number detecting section 22 reads the incoming signal from the subscriber accommodation section 20 and detects the caller number. The detected subscriber number is stored in the sender number storage unit 2
5 will be notified. The control unit 24 uses the caller number storage unit 25
Search whether the caller ID received in is registered.

If not registered, the request from the sender is ignored. If registered, the message number is read from the sender number, and the voice message of the same message number stored in the voice message storage unit 26 is transmitted from the transmission unit 28 to the line 1.

After sending the voice message, if the recording active flag is set, the control unit 24 activates the recording unit 29, and when a voice message from the other party comes in from the subscriber accommodation unit 20. , Record the message 2
Record to 9. If the recording active flag is not set, a signal is sent to the subscriber accommodation unit 20, the hook is returned to the on-hook state, and the line is disconnected.
