Abstract

PURPOSE:To realize the same function as the transfer function by considering to be absent when the absent transfer destination is not set to a certain extension and the response is not performed to the reception of the prescribed number of times or above, judging automatically the destination sequence with high probability and informing a telephone opponent of the extension numbers by the voice. CONSTITUTION:Each time an extension (1) 101 sets a transfer destination to a certain extension, when a control means 112 recognizes through an extension circuit means 103, the number of times absent-set to each extension is counted to a counter corresponding to each extension in a storing means 111, when the absent transfer setting is forgotten, made absent, and incoming is received from other telephone, the counter of the storing means 111 is referred to, and by a voice synthesizing means 110, in the sequence from the extension number with many absent settings, the extension number is informed to a calling party by a voice.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private automatic branch exchange having a call forwarding service for automatically forwarding an incoming call to an extension to a registration destination.

[0002]

Call forwarding service provided in a private branch exchange or a key telephone system is used when a user of an extension leaves the extension and moves to another place.
It is a well-known fact that if a destination is registered, incoming calls to the extension thereafter will be automatically transferred to the destination.

Generally, the following four forms are known as forms of the call forwarding service. The first form is a form in which when an incoming call arrives at an extension, the incoming call is always transferred to the registration destination, and no incoming call at the extension occurs.

The second form is a form in which, when an incoming call arrives at an extension, the incoming call simultaneously occurs at both the extension and the registration destination, and the call is connected to the person who answers first.

The third form is a form in which, when an extension is received, if the extension is not busy, the extension is received as it is, and only when the extension is busy, the incoming call is received at the registration destination. ..

A fourth form is a form in which, when an incoming call arrives at an extension, the incoming call once arrives at the extension and is forwarded to the registration destination only when there is no response for a certain period of time.

[0007]

However, in the above-mentioned forms of the conventional unattended transfer method, it is necessary to set the transfer destination each time when leaving the seat, and if the setting is forgotten, the transfer is not made and frequently. There was a problem that the transfer destination to be set must be set each time the user leaves the desk.

An object of the present invention is to provide a call forwarding method that solves the above-mentioned conventional problems.

[0009]

In order to achieve the above object, the present invention provides a voice synthesizing means and a storage area for each extension for newly storing a set number of times for each transfer destination set by the extension, and absent transfer. At the time of setting, a setting means is provided for counting the number of times the corresponding transfer destination is set, and for notifying the extension number to the other party by voice when the absence transfer destination is not set in the absent state ..

[0010]

According to the present invention, with the configuration described above, even if the transfer destination that is frequently set is not set each time the user leaves the desk, or even if the setting is forgotten, the extension numbers are called in the order of high possibility of destination. The function equivalent to the transfer function can be realized by notifying the other party by voice and calling the extension number of the other party.

Mutual connection with 1, 102, and extension 101, 102
And a voice synthesizing means mutually 110. Reference numeral 111 is a storage means for storing the absent transfer destinations registered from the extensions 101 and 102, the number of absent transfer settings for each absent transfer destination, and 112 is the extension circuit means 1
03, 104, station line circuit means 107, 108, voice synthesizing means 110, communication path means 109, and storage means 111.

In FIG. 2, 201 and 205 are absent transfer registration flags indicating whether or not the extension is registering an absent transfer destination, and this flag is true during registration. Also, 2
02 and 206 are absent transfer destination data that are valid only when the absent transfer registration flags 201 and 205 are true and in which the absent transfer destination is registered. .. Reference numerals 203, 204, 207 and 208 are number counters in which the extension m (m = 1 to n) is set as the absent transfer destination.

In the private automatic branch exchange according to the present embodiment having the above-mentioned structure, the operation and control process will be described below with reference to the drawings in order to explain the present invention.

First, registration of the absence transfer destination (step 30)
0) and the processing at the time of cancellation (step 310),
A description will be given based on FIGS. 1, 2 and 3. Extension (1) 1
When the control means 112 recognizes the absent transfer registration operation from 01 via the extension circuit means 103, the absent transfer registration flag 201 corresponding to the extension is set to true (step 30).
1) The transfer destination is stored in the absent transfer destination data 202 (step 302). Here, if the extension indicated by the absent transfer destination data 202 is the extension m, the number counter (any of 203 to 204) that sets the extension m as the absent transfer destination is incremented (step 303). At the time of cancellation, the same processing as at the time of registration is performed. When the control means 112 recognizes the operation of canceling the absence transfer from the extension 101 via the extension circuit means 103, the absence transfer registration flag 201 corresponding to the extension.
Is set to false (step 311), and the absence transfer destination data 202 is set.
Is also cleared (step 312), but the frequency counter (2
Any one of 03 to 204) remains.

As described above, the absent transfer setting is performed several times, and the number counters 103 and 20 of the storage means 111 are set.
After a certain number of times has been stored in 4, 207 and 208, as will be described below, if the user does not answer the incoming call more than the set number of times even if he / she forgets the absence setting or does not perform the absence setting. Can be judged to be absent, and an extension number with a high possibility of destination can be notified by voice.

Next, the processing (step 400) at the time of calling from extension to extension will be described with reference to FIGS. 1, 2 and 4. Now, it is assumed that a call operation is made to the Nth extension (n) 102 by the first extension (1) 101 (step 401). The control means 112 firstly makes the Nth extension (n).
102 to receive an incoming call. It is checked whether the Nth extension (n) 102 answers the incoming call within the set number of times (step 402). If you respond within the set number of times,
Exit without doing anything. When it does not respond to the incoming call more than the set number of times, it is judged as absent, and whether or not the Nth extension (n) 102 which is the called extension is registering the absent transfer destination is referred to the absent transfer registration flag 205. And check (step 403). If the absent transfer registration flag 205 is true, the transfer destination (extension m) stored in the absent transfer destination data 206 is called (step 40).
4). Absent transfer registration flag 205 of the Nth extension n102
Is false, the voice synthesizing means 110 is set to the communication path means 10
9, the first extension (1) 10 via the extension circuit means 103

Go to 1 OGM (outgoing) saying, "I'm absent, so I'll say the extension numbers in descending order of possibility of destination."
message) is transmitted (step 406). After that, the Nth extension (n) 102 checks the value of the number counter 207 in which the extension 1 is set as the absent transfer destination or the number in the number counter 208 in which the extension n-1 is set as the absent transfer destination, and m
More than one time is detected (step 407). Among the detected ones, the extension numbers are arranged in descending order of the set number of times, the voice synthesizing means 110, the communication path means 109, and the extension circuit means 10.
1-Extension 1 (1) 1 by voice on the route of 3-extension 101
01 (step 408). In this way, the first extension (1) 101, which has been informed of the extension number having a high possibility of destination, calls any one of them,
The function equivalent to call forwarding can be obtained.

In this way, if the absent transfer destination is set only for a certain period of time, after that, the storage means 11 stores the frequency of setting the transfer destination.
Since 1 is stored, the extension number having a high possibility of the destination can be notified by voice as described above even if the setting is not made one by one or the setting is forgotten.

Further, if the transfer destination is set frequently and surely, one of the counters of the storage means 111 may become full. In that case, a constant value is subtracted from all the counters. It is sufficient to devise such as doing.

Although the case where the extension telephone makes a call to another extension telephone has been described above, it goes without saying that the same service can be performed when the extension telephone makes a call.

The private branch exchange of this embodiment also includes a small-sized key telephone system.

[0022]

As described above, according to the private automatic branch exchange of the present invention, the voice synthesizing means and the storage means for storing the number of times the absent transfer destination is set for each extension number are frequently set. Even if you do not set the forwarding destination, or if you forget to set the absence forwarding destination when you leave your desk, you will hear the extension number that is likely to be the destination for the calling telephone. It is possible to provide notification, and it is possible to provide extremely convenient services.
