Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a method for selecting one extension specified by the outside line from among a plurality of extensions when a call is received from an outside line. The present invention relates to an extension selection device connected to an outside line.

(Prior Art) A conventional device of this type was constructed as shown in FIG.

In this figure, 201 is a switching device, LL.

L2 . . . is an outside line taken into this switching device 201, El, E2 . . . . is an extension telephone connected to this switching device 201, K is a representative extension telephone, and 0 is an outside caller.

When this incoming call from caller O appears on outside line Ll, representative telephone set K is called. When the operator responds to this, a communication path 11 is established.

Here, the caller O tells the operator that he or she wishes to call the extension telephone E1, for example, and the operator puts the call path 11 on hold and calls the extension telephone E1 by dialing the extension, and the extension telephone El answers the call. By doing so, the communication path 12
is formed.

Then, the operator at the representative telephone informs the extension telephone El that the call is from the calling party O, and puts the representative telephone K on hook, thereby forming a communication path 13, which connects the calling party O and the extension telephone E1. You will be able to establish a call with.

In this way, in the conventional device, the caller O can make a call to the desired extension by specifying the extension to the operator of the representative telephone.

However, with this conventional device, there is a problem that if the representative telephone K is occupied, the extension that caller 0 wants to call cannot be called even though this extension is currently free. There was a reasonable point.

(Problem to be Solved by the Invention) As described above, in the conventional device, there are cases in which calling party O is unable to call the extension even though the extension he wants to call is currently vacant. There is a problem.

There is also the problem that a representative telephone is required, which is actually used only for calling extensions.

The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to ensure that if the extension that the caller wants to call is vacant, the caller can certainly call that extension. In addition to making it possible to create a communication path between the calling extension line and the calling outside line without requiring a representative phone like in conventional equipment. The purpose of this invention is to provide an extension selection device.

[Structure of the invention]

(Means for Solving the Problems) The extension selection device of the present invention registers the identification voice data of each extension in the storage means in advance, and when a call is received from an outside line, the extension selection device is first designated by the first message sending means. A first message signal for prompting voice input is sent to the outside line, the caller is asked to specify the extension by voice, the voice is generated as extension designation voice data by the voice processing means, and this is used as the above-mentioned identified voice. The switching means determines the extension of the calling light by comparing it with the data, calls the extension by the incoming call control means when the calling light is on-hook, and connects the extension and the outside line when there is a response. The device is turned on to establish a communication path.

(Function) According to the present invention, when a caller specifies an extension by voice, a calling optical extension is determined based on this data, and when the hook status is on-hook, that extension is called;
Since this extension answers and goes off-hook, it is possible to make a call, so if the extension the caller wants to call is free, the extension can be reliably called. , there is no need for a representative telephone like in conventional devices.

That is, the SW matrix control means, incoming call detection control means, and voice recognition means in the outside line unit of the outside line connected to this extension 11 are returned to the above-mentioned initial state.

Next, the operation of the telephone device configured as described above will be explained.

First, when a call is received from the external line L2, for example, the output of the incoming call detection control means 13B becomes "H", the switch IB is turned on, and the message sending means 14B is activated to send a message signal to input the extension designated voice. is outside line L
2, and after the termination, a termination notification signal is input to the audio signal processing means 18B, and this is activated.

Thereafter, when a voice signal enters the voice signal processing means 18B from the outside line L2, the voice recognition process is performed on it, and the comparison means 1
Input to 9B and 20B. For example, if extension 11 is specified, the output of comparing means 19B becomes "H".

At this time, this extension! If (2) is not in use, the output of the AND circuit 21B becomes "H", so the incoming signal generating means 11 is activated and a call is made to the extension 11. When this extension 11 goes off-hook and responds, the LINE circuit 5
An external line selection signal is generated from a, and the SW matrix control means 6B turns on switches 2B and 3B to select the external line L2.
A communication path between the extension line 11 and the extension line 11 is established. At the same time, the SW matrix control means 6B prohibits the switch 4B from being turned on.

On the other hand, since the stop signal is input from the LINE circuit 5a to the comparison means 19B, its output becomes "L", and the output of the AND circuit 21B becomes "L", and the incoming signal generation means 1
The output of the calling signal of 1a is stopped.

Further, when an incoming call is received from the other external line LL while the extension 11 is ringing or the extension 11 is off-hook, the output of the incoming call detection control means 13A becomes "H", and the switch 1A
is turned on, the message sending means 14A is activated, and a message signal is sent to the outside line Ll to input the extension designated voice, and after that, a termination notification signal is input to the audio signal processing means 18A, which is activated. Ru.

Thereafter, when a voice signal enters the voice signal processing means 18A from the outside line L1, the voice recognition process is performed on it, and the comparison means 1
Input to 9A and 2OA.

For example, if extension 12 is specified, comparison means 2
If the output of OA becomes "Ho" and extension 11 is designated, the output of comparing means 19A becomes "H#".

At this time, since extension L2 is vacant, the AND circuit 23
Since the output of A becomes “Ho”, the incoming signal generating means 11b
is activated and a call is made to extension L2. When this extension line L2 goes off-hook and responds, an external line selection signal is generated from the LINE circuit 5b, and the SW matrix control means 6
A turns on the switches 2A and 3A, and a communication path between the outside line L1 and the extension line L2 is established. At the same time, the SW matrix control means 6A prohibits turning on the switch 4A! I'm getting fucked.

As a result, two communication paths are formed: the outside line L2 and the extension L1, and the outside line Ll and the extension 12. However, since the switches 4B and 3A are prohibited from turning on, they cannot communicate with each other. There will be no confusion.

On the other hand, since the stop signal is input from the LINE circuit 5b to the comparison means 2OA, its output becomes "L", and the output of the AND circuit 23A becomes "L", and the incoming signal generation means 1
The output of the calling signal of 1b is stopped.

Further, when the extension 11 is specified from the outside line LL, the output of the comparing means 19A becomes "Ho", but at this time, the OR circuit 1
2a outputs "H", and the inverted signal "L" is input to the AND circuit 21A, so the output of the AND circuit 21A becomes "L", and the calling signal is output from the incoming signal transmitting means 11a. It will never occur.

On the other hand, the AND circuit 25A receives "Ho" from the OR circuit 12a.
“H” is input from this AND circuit 25A.
o is output, the in-use message sending means 27A is activated, the in-use message is sent to the outside line Ll, and upon completion of this, a reset signal is output from the circuit 27a,
The incoming call detection control means 13a and the voice recognition means 15A are reset, the switch IA is turned off, and the line is disconnected.

The call between the outside line L2 and extension 11 ends. That is, when either of them goes on-hook, the various control means are reset as described above by a reset signal from whichever is faster, from the end of call detection means 28B or the end of call detection means 29g.

As described above, according to this embodiment, extension II.

If 12 is not ringing or off-hook, it can be called.

Although one embodiment of the present invention has been described above, the following is also possible.

ROMs 16A and 16B are identification voice data storage means in the voice recognition means 15A and 15B.

17A and 17B may be stored with identification voice data of the name of the user of the extension they are in charge of, so that a caller from an outside line can specify the extension using this name.

When using one extension for multiple users, each ROM16A, 1
Multiple names are registered for 6B, 17A, and 17B, and comparison means 19A, 19B, and 2OA.

20B, if it matches, the output is “Ho”.
It is better to do so.

Further, in the case of system expansion of the above-described embodiment, an additional external line unit may be added to add an external line, and an additional extension unit may be added to add an extension line.

(Effects of the Invention) As explained above, according to the present invention, when the calling party specifies an extension by voice, the calling optical extension is determined by voice recognition and that extension is called. , any extension can be called without the need for a representative telephone.
