Abstract

(57) [Summary] [Purpose] Automatically connect to an extension phone from outside. [Structure] The other party's telephone number, # symbol, and extension number are dialed from the input unit 2. A dial signal is output from the dial signal generator 1, the telephone number is sent to the receiving side,
The # signal is detected by the code detection unit 3, and the detected # signal and extension number are stored in the storage unit 4. The transmitted telephone number is received by the receiving side, and the automatic incoming call unit 8 automatically receives the incoming call. Since the polarity on the transmitting side is reversed when an automatic call is received and the terminal goes off-hook, the response signal detecting section 5 detects the polarity reversal and sends out the # signal and the extension number stored in the storage section. The receiving side identifies the transmitted # signal and extension number by the extension number identifying section 9, and the switching section 10 connects the line 11 to the corresponding extension.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a telephone, and relates to a device for automatically connecting to an extension telephone by dialing an extension telephone number of the other party.

[0002]

[Prior Art]

 In the past, when a telephone call was made to a business office, etc., the exchange receives a telephone call from the outside, talks with the other party, asks for the name, affiliation, extension number, etc., checks the applicable extension number, and calls the extension number. I was connected to the other party's phone. It is becoming difficult to place an exchanger in the current situation of labor shortage. Under such circumstances, the emergence of a device that automatically calls and connects an extension telephone from the outside without placing a switch is desired.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the problems of the above-mentioned conventional technology, and automatically connects to an extension telephone from the outside.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides an input unit for inputting the telephone number and extension number of the other party, a dial signal generation unit for generating the input number, a code detection unit for detecting the extension number, and the detected extension. A storage unit that stores a number, a response signal detection unit that detects a response signal, and a first control unit that controls the input unit, dial signal generation unit, code detection unit, storage unit, and response signal detection unit. , An automatic incoming call unit that detects a ringing signal and automatically receives an incoming call, an extension number identification unit that identifies an extension number, a switching unit that connects a line to the identified extension telephone, and the automatic incoming call unit, an extension number identification unit and a switching unit And a second control unit for controlling the telephone.

[0005]

[Action]

 According to the above configuration, the other party's telephone number, # symbol and extension number are dialed from the input section. A dial signal is output from the dial signal generation unit, the telephone number is sent to the receiving side, the # signal is detected by the code detection unit, and the detected # signal and extension number are stored in the storage unit. The sent telephone number is received by the receiving side, and the automatic receiving unit automatically receives the call. Since the polarity on the transmitting side is reversed when an automatic call is received and the terminal goes off-hook, the response signal detection unit detects the polarity reversal and sends out the # signal and extension number stored in the storage unit. The receiving side identifies the transmitted # signal and extension number by the extension number identification section, and the switching section connects the line to the corresponding extension.

【Example】

 Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing an embodiment of a telephone of the present invention, and FIG. 1 is a diagram showing an operation sequence of the telephone of the present invention. In the figure, 2 is an input unit for inputting a telephone number and an extension number. Reference numeral 1 is a dial signal generator, which sends the input signal input from the input unit 2 as a dial signal. A code detector 3 detects the # signal by inputting, for example, a # symbol between the input telephone number and extension number. A storage unit 4 stores the extension number following the # signal detected by the code detection unit 3 in the storage unit. Reference numeral 11 is a line that connects telephones via an exchange. Reference numeral 8 is an automatic incoming call unit, which receives an incoming call signal and makes an automatic incoming call (off hook). Reference numeral 5 is a response signal detection unit, which detects the polarity inversion because the response signal returns to the transmission side and reverses the polarity of the telephone line when the receiving side automatically receives the call, and the extension number stored in the storage unit 4 is transmitted. To do. A first control unit 6 controls the input unit 2, the dial signal generation unit 1, the code detection unit 3, the storage unit 4 and the response signal detection unit 5. An extension number identification unit 9 identifies the received extension number. A switching unit 10 connects the extension unit to the extension number identified by the extension number identification unit 9. A second control unit 7 controls the automatic call receiving unit 8, the extension number identifying unit 9 and the switching unit 10.

FIG. 2 shows an operation sequence of the telephone, which will be described with reference to the operation sequence. The calling party (sending side) 13 dials the telephone number and extension number of the called party (receiving side) 14 from the input section 2. Insert a # sign between the telephone number, eg, 111-2222 and the extension number, eg, 33. That is, enter 111-2222 # 33. Only the telephone number "111-2222" is sent to the called party 14 as the selection signal 15 (push button dial signal), and the line connection operation is performed. The code detection unit 3 detects the # signal and stores the # signal and the extension number "# 33" following the # signal in the storage unit. The ringing signal 16 is output, the bell of the called party 14 rings, and the automatic receiving unit 8 automatically receives 17 and turns off. The answer signal 18 is returned to the calling party 13 and the polarity of the telephone line is reversed. The response signal detection unit 5 detects this polarity inversion, reads the # signal and the extension number “# 33” 19 stored in the storage unit 4, and sends them to the called party 14. The extension number identification unit 9 identifies the # signal and the extension number 19, and the switching unit 10 connects the corresponding slave unit (extension telephone) and generates a ringing tone. The child machine goes off-hook and enters the call 20.

[0008]

[Effect of the device]

 As described above, according to the present invention, the effect of being able to automatically connect to the extension of the other party by dialing the telephone number followed by the extension number is great.
