Abstract

PURPOSE:To enable called extension to catch originating extension subscriber's number in incoming during absence by making calling extension register setting by dialing special number when no reply is given by a called extension. CONSTITUTION:When no reply is given from a called extension B, originating extension A makes hooking to set incoming during absence and dials a special number. Then, an originating register 3 counts and accumulates dial pulses, and a special number discriminating device 4 sends special number information to a central controlling unit 6. The unit 6 accumulates the information corresponding to an accumulating device 7 of an incoming information during absence and lights up a lamp in the extension A. When the extension B dials the special number thereafter, the unit 6 reads out number information of the extension A from the device 7 and transfers it to a voice composing device 5, and sends out the number of the extension A as an aural signal from the device 5. Thus, the extension B is informed of incoming from the extension A during absence.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for informing a called extension subscriber of the calling party's extension number of an incoming call during an absence in an automatic private branch exchange.

In extension interconnection, if the called extension subscriber is absent or does not answer, the calling extension may learn that there is no answer and call again, or the absent party may transfer the call to a predetermined location and send the call to the destination. The method used was to pick up the phone or have an agent act on your behalf. However, if the forwarding destination is not determined or there is no agent, there is a drawback that the called extension subscriber cannot know the calling party's extension number of the incoming call while the caller is absent.

The purpose of the present invention is to enable the called extension subscriber to know that a call has been received during the missed call by the calling extension subscriber performing a certain operation when the called extension subscriber receives a missed call. To provide a system for notifying the other party's number of an absent incoming call by which the calling extension subscriber number can be known by the operation of the operator.

Absence according to the present invention to achieve the said object. The system for notifying the other party's number of an incoming call is equipped with a message waiting lamp for the extension subscriber, and a special number identification device for identifying whether or not the number sent from the calling extension subscriber is a special number; A voice synthesizer that converts telephone number information into speech and a caller information storage device for missed incoming calls are provided, and the caller information is sent by the calling subscriber while the called subscriber is ringing, and received and stored by the calling register. When the special number identification device identifies the number as a special number, it identifies the accommodating location of the called extension subscriber during the call, and stores the calling extension subscriber number information and the accommodating location of the called extension subscriber in the storage device. The special number identification device stores the information and activates a message waiting lamp of the called extension, and then recognizes the number sent by the called extension via the calling register as a special number. When the identification is made, the calling subscriber number information stored in the storage device is read based on the called extension subscriber accommodation location information from the calling register, and the called subscriber number information is converted into a voice signal by the speech synthesizer and the called The calling subscriber number is configured to be sent to the subscriber.

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are block diagrams showing an embodiment of an automatic private branch exchange to which the system of the present invention is applied.

In the state shown in FIG. 1, the calling extension is calling the called extension B. When there is no response from the called extension B, the calling extension A hooks up to set up call termination in the absence, and the calling extension person is connected to the calling register (OR, T) 3. After confirming the special dial tone, the user dials a special number for setting the missed call transmission, and the calling register 3 counts and accumulates dial pulses every time the calling extension A dials.

At the same time, this dialing information is sent to the Special Number Identification Unit (SNAU).
) sent to 4. The special number identification device 4 analyzes whether the received number is a special number, and if it is a special number, sends special number information to the central control unit (OO)s. At the same time, calling extension number information is sent from the calling register 3 to the central control unit 6. When the central control unit 6 receives these information from the calling register 3 and the special number identification device 4, it identifies the accommodation location of the called extension B while the calling extension is ringing, and identifies the number information of the calling extension A and the called number. The accommodation location information of extension B is stored in correspondence with the missed call information storage device CM)7.

At the same time, the central control unit 6 sends the message of the called extension B.
Turn on the waiting rung.

When the called party who was away returns, he or she can look at the lamp and know that a call has been received during his or her absence.

Then, in order to know when extension B has received a call while he is away, when he dials a special number for calling missed call information, the calling register 3 counts and accumulates dial pulses every time extension B dials, and at the same time, this dial information is It is sent to the special number identification device 4. The special number identification device 4 analyzes whether the received number is a special number or not, and sends special number information to the central control device 6. At the same time, calling extension accommodation position information is sent from the calling register 3 to the central control unit 6. Based on this information, the central control device 6 reads the number information for extension B, that is, the number information for extension A, from the missed call information storage device 7 and transfers it to the voice synthesis device (VPT) 5. At the same time, as shown in Fig. 2, the voice synthesizer 7 is connected to the line circuit (LC) 2 connected to the extension
) connect via s.

Thereafter, the voice synthesizer 5 converts the number of extension A into a voice signal and sends it out, and extension B learns that a call has been received from the busy extension person during his/her absence and hooks up the telephone. The central control device 6 takes in the hook-on information from the line circuit (LO) 2, disconnects the voice synthesizer 5 from the line circuit, turns off the message waiting lamp of extension B, and at the same time stores information in the missed call information storage device 7. The information corresponding to extension B of is deleted.

As explained in detail above, according to the present invention, in extension interconnection, if there is no response from the called extension, the calling extension dials a special number and performs registration settings, and then the called extension dials the special number. By doing so, the called extension can hear the number of the calling extension by voice, and has the effect of being able to know the number of the called party while the caller is absent.
