Abstract

PURPOSE:To decrease the wait time and to improve the efficiency of an extension telephone network by reading a message of an absence registration section of a pushbutton telephone set of a transmission destination when the absence setting is detected and sending the message to a pushbutton telephone set being a transfer sender. CONSTITUTION:When the user of a pushbutton telephone set 3 leaves its seat, the user sets an absence setting section 36 to set the absence state and to record a message representing the absence to an absence state registration section 37. A transfer party uses a transfer function of other telephone set 3 of a master set 1 to request the transfer processing to the master set 1 with respect to a telephone set of an external line in busy with a telephone set 2. Then the master set 1 confirms the absence state of the called party set to the absence setting section 36 of the telephone set 3. When the absence state is detected, the message registered in the registration section 37 of the telephone set 3 being the transfer destination is read and it is sent to the telephone set 2 being the transfer sender from an absence state transmission section 102. When the transmission of the message is finished, a speech return section 103 restores the connection of the telephone set of the external line to the telephone set 3. Thus, the wait time is decreased and the efficiency of the extension telephone network is improved.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a call transfer function of a telephone analysis system using a button telephone having various functions such as a speed dial function. The present invention relates to a key telephone transfer system suitable for efficiently returning to the original call when the user of the fixed telephone is absent.

[Conventional technology]

In recent years, II! Customer requests for air communication are so-so.
It is becoming more diverse and sophisticated. In particular, telephone devices for voice communication have evolved from the development of button telephones that perform button dialing to include more functions.

The button dial replaces the conventional rotary dial by combining a push-button dial switch with an integrated circuit that electrically generates a dial pulse signal.

In this way, electronically controlled key telephones are equipped with various button functions in response to customer requests.

For example, you can use the redial function, on-hook dial function, call time display function, and (-1) to register the dial number in advance and input the shortened Lt-1!f number to automatically change the registered dial number. Dial memory function to select (
There is also an answering machine function that sends out a pre-recorded response message using a cassette tape or IC memory and records the requirements of the other party based on an automatic response even when the person is not present.

Furthermore, at present, what is called a system type telephone device, which constitutes a telephone network within an area using so-called extension telephone lines, is widely used. That is, from any phone,
With functions such as making and receiving calls to any central office line, holding a call on a central office line, and transferring a call to another telephone, you can
This makes it possible to efficiently use multiple office lines with multiple power/disconnection switches.

Regarding such regular disconnections, please refer to the Institute of Electronics, Information and Communication Engineers' ``Information and Communication Handbook'', PP, 2677-2.
682.

Now, as mentioned above, various additional functions and functions have been added to the W4 III telephone disconnection machine, and the importance of the telephone has been increasing. Especially within large companies,
The frequency of using business telephones to call and disconnect telephone lines through extensions has become very public. In many system configurations, for example, the operator receives a series of calls from an outside line at a representative telephone, and then transfers the call via this representative telephone to the connection destination desired by the user on the outside line. It is used.

To transfer outside calls during calls like this, key telephones have various functions! IN;) has been done. For example, there is a transfer function described in pages 18 to 21 of "Key Telephone System EE-S Series Instruction Manual" published by Ricoh Co., Ltd. In particular, in call transfer processing, there are "direct transfer function" and "announcement transfer function" as additional functions to handle cases where the other party is absent.
This is to reduce the time loss that occurs when the user of the transfer destination telephone is away from his or her desk in the transfer process.

In other words, if the user of the forwarding destination phone has declined the call, the person using the phone 4 that received the outside call will wait for a while and then notify the person that the user of the forwarding destination phone is unavailable. , connection 87 () is returned to the transfer source button telephone (2,
was. As a result, the transferor was unable to perform other tasks during the transfer period, resulting in a loss of time.

(7. Direct transfer function) With the transfer function, the transferee can dial the transfer destination's extension number and immediately hang up the phone. I am able to get started on my work.

If the transferred user does not respond, the connection is automatically returned to the transferred telephone after a predetermined period of time has elapsed.

[Problems to be Solved by the Invention] Based on this, in such conventional button/telephone devices, consideration must be given to the time loss of the user during transfer processing, when connecting external lines, and when disconnecting. had not been done.

In other words, if the user of the key telephone to which the external line is being forwarded is absent, the user of the key telephone to which the external line is to be forwarded to is not available, and the transfer process using the "direct transfer function" or "announcement transfer function" is different from the conventional method. Had to wait for no time.

Note that one of the functions of key telephones is the "absent setting J", but this is only for the receiving party to notify the incoming call with a lamp display without the telephone ringing. In terms of processing, it was rather inconvenient.

In addition, in order to reduce the waiting time for users of telephones receiving external calls, it is possible to shorten the fixed waiting time for a response using the "direct transfer function" or the "announcement transfer function."
However, in that case, due to a delay in the response of the user of the transfer destination key telephone simply picking up the handset,
There is a problem that the transfer may be canceled and the transfer process cannot be performed reliably.

The purpose of the present invention is to solve the problems of these conventional techniques, and
In the forwarding process of a button telephone, if the called party is absent, the forwarding party's phone is automatically notified of his/her absence and the connection is immediately restored. To provide a key telephone transfer processing system that improves the efficiency of an extension telephone network based on less waiting time.

[Means to solve the problem]

In order to achieve the above object, the button telephone transfer processing system of the present invention provides a first button telephone and a second button telephone when a user of the button telephone leaves the installation location of the button telephone. Based on the settings, the main device includes an absence setting unit that indicates the user's absence status, an absence status registration unit that registers a message indicating the user's absence status, and the main device includes a second button telephone from the first button telephone. Based on the transfer request to the key telephone, an absentee setting detecting section detects the absent state of the user set in the absentee setting section of the second key telephone; The absence status sending section reads the message registered in the absence status registration section of the first button telephone and sends it to the first button telephone.When the message sending by the absence situation sending section is completed, the outside line telephone that was on hold at - and,
The present invention is characterized by the addition of a call return unit that connects to the first button telephone and returns the call.

[Function] In the present invention, when the user of the button telephone leaves his/her desk, the user sets the absence setting section to indicate that he/she is absent, and also sends a message indicating the absence status to the absence status registration section. Record it in

When performing transfer processing to switch the connection of an outside line telephone that is currently in use on the first key telephone to another key telephone that is connected to the same main unit by extension, use the transfer function of the first key telephone. , the transferor requests the main device to perform the transfer process.

Based on the transfer request, the main device checks the absence status of the called party, which is set in the absence setting section of the second key telephone set as the transfer destination.

If the absence setting is not made, the transfer destination waits for a response and performs the conventional transfer process. Based on this, when the absence setting is detected, the message registered in the absence status registration section of the second key telephone to which the transfer is made is read, and this message is sent to the first key telephone which is the transfer source.

Once the message has been sent, change the outside line telephone to the
button to restore connection with the phone.

In this way, when the transferer transfers an active outside line call to the key telephone set with the registered absence setting, the transfer process is not accepted and the call is automatically returned.

With this configuration, the following operations are performed.

First, when a caller calls the telephone network of this system from an outside line, for example, the central office line (1) 14 and the central office line circuit 17 are called.
It is input to Dosei ffl via .

On the main device l side, for example, key telephone (1) 2
Set it as the representative phone for connecting to an outside line.

As a result, the caller's telephone is controlled by the main device control unit 12 and the call path switch 11. It is connected to the button telephone (1)2 via (1)4.

The representative of button telephone (1) 2 picks up the handset and
Make a call with the caller.

Based on this, the representative uses the dial unit 25 to call the button telephone 3 of the party the caller really wants to talk to, for example, and performs a transfer process.

That is, the data specifying the transfer destination using the dial 25,
Using a function button (not shown), transfer instruction data is sent to the main device 1 via the data transmitting/receiving circuit 23, extension (1) 4, and data transmitting/receiving unit 13. Then, the main device 1 switches the call from the central office line (1) 14 to the key telephone (n) 3.

Based on this, if the user of the key telephone (n) 3, which is the forwarding destination, is absent, the user of the key telephone (n) 3 sets the absence setting section 36 of the key telephone (n) 3 in advance based on the settings. , and the absence status data is registered in the absence status registration section 37 as, for example, a message.

Note that this message may be registered by using a character string selected from a menu already registered in the system, or by recording it as a voice on an IC such as that found in an answering machine. According to this recording method, for example, it is possible to freely register absence status data such as when and where the person will be present.

In this way, when the absence setting section 36 of the button telephone (n) 3 is set, the main device 1 detects the absence setting detection section 101.

On the other hand, the key telephone (1) 2 on the representative side displays the absence status data sent from the main device 1, for example, on the display section 22 of the key telephone (1) 2, and at the same time, the key telephone (1) 2, which is the return tone of the transfer, displays the absence status data sent from the main device 1. Based on the back tone, to the representative,
The absence of the button telephone (n) 3 is notified.

Then, the representative's key telephone (1) 2 is automatically connected to the caller.

In this way, the representative can immediately know the absence of the transfer destination user and can automatically return the call to the caller.

Note that the method of expressing the message is not limited to the display on the display unit, but may also be a method using voice. This allows messages that exceed the physical limits of display display to be registered. The representative who has been notified of the transferee's absence must quickly inform the caller of the outside line of the exact circumstances of the transferee's absence, such as why, for how long, and where the transferee is going. I can do it.
