BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wireline telephony technology, and more particularly, to a digital trunk line integrated information providing device connected between a telecommunication operator's local exchange and an enterprise's private exchange to provide additional services for the enterprise. As used herein, the term "exchange" refers to an exchange that forms part of a public network (PSTN) held and maintained by a backbone telecommunications provider.

R2 MFC digital trunk line is defined for the exchange of information on connection establishment, control and management in ITU-T. Local exchange and private exchange are connected by E1 / T1 network and use DID ( Direct Inward Dialing service can be provided. The R2 (register) signal is generated by combining multiple frequencies. R2 signaling is used in analog section and digital section such as E1 / T1. When used in the analog section, one-way operation is the default, and in the digital section, the two-way operation is the default.

PRI (Primary Rate Interface) method (23B + D, 30B + D) adopted for ISDN trunk line is the national exchange. Widely used in private exchanges (PBXs), etc., mainly used in PBXs mainly for trunks, and PRI used to connect the system is based on T1 and based on E1. The PRI method based on T1 is composed of 23 B-channels and one D channel (64kbps), has a T1 transmission rate of 1.544 Mbps, has B8ZCS and AMI line coding compensation method, and the PRI method based on E1 is 30 Composed of two B-channels and one D-channel, it has an E1 transmission rate of 2.048 Mbps and uses HDB3 line coding.

DID [DIADI] is a service that assigns a portion of a range of telephone numbers to a company's private exchange from a local telephone company. Using DID, companies can provide a separate telephone number for each employee without actually having to connect as many lines as the number assigned to their exchange.

The technique of providing information instead of ringback tones sent during the conventional incoming period has been provided in the national exchange. Recently, a technology for providing such a function has been commercialized in a private exchange, but Korean Patent Application No. 2003-25990, which was invented and filed by Yoon-Kyung et al., Discloses a technique for providing a ring back tone in a private exchange.

This prior art can provide a different ring back tone for each extension number of a private exchange, but in order to use this, there is a problem in that it is not a new buyer because it needs to exchange an existing private exchange. In addition, in the case of the R2 MFC type direct inward dialing (DID) or PRI type digital trunk line, there is a problem in that an extension ringing service should be subscribed to a main communication service provider for each extension telephone.

In addition, the conventional private exchange not only could not easily manage the information related to the call from the computer of the premises, there was a problem in that expensive recording equipment must be installed separately for recording.

The present invention is to solve such a problem, it is an object of the present invention to provide an incoming ring through the additional equipment without replacing the existing private exchange.

That is, the existing ring tone providing devices are implemented in the switchboard, and the ringback tone itself is the sound source in this case since the ringer is connected to the terminal by releasing the call when the called terminal answers. It is sent out. However, the present invention has the advantage that it can be implemented by a very simple circuit because it operates by replacing the ringback tone by editing the R2 signal sent from the private exchange while monitoring the call establishment process between the exchanges.

Furthermore, the integrated information providing apparatus according to another aspect of the present invention records the call content in the form of a digital file when a call response signal is detected from the private exchange side, and terminates the recording at the end of the call.

According to this aspect of the present invention, the integrated information providing apparatus according to the present invention can not only provide a recording function with a simple device, but also accurately recognize a call start time and end time for an extension number for which recording has been made without any manipulation. It is possible to record by recording.

According to an additional aspect, the recorded file is managed along with the call log information and can be viewed or played back and listened to on the client computer through the network.

When the integrated information providing apparatus according to another aspect of the present invention receives a call from an incoming call number with an automatic answer set up from the outside, it receives the call and connects to the answering replay unit to provide an automatic reply message, for example, DTMF tone It is possible to control the reply message according to the operation command detected by the above, or to set up and transfer a call to the private exchange side using the received information.

According to another aspect of the present invention, the integrated information providing apparatus according to an embodiment of the present invention provides an automatic response sound source database 339 for storing an automatic response sound source, and a sound source instructed among the sound sources stored in the automatic response sound source database 339. It may further include an automatic response playback unit 331 for reproducing. At this time, when the incoming call number detected by the reception information editing unit 130 is a number for which an automatic answer is set when the call setup request is received from the outside, the signal controller 500 connects the corresponding call to the automatic answer reproducing unit 331 and plays the call. It provides the sound source, and controls the reproduction of the sound source of the answering machine playback unit 331 according to the operation command detected by the reception information editing unit 130. That is, when a call setup is requested with a called number for which an answer is set, the signal controller 500 sets up a call path with itself in response to the call, and connects the set call to the answer answering unit 331. Accordingly, the comments played by the answering machine replay unit 331 may be provided to the caller.

According to an additional aspect, an automatic premises exchange may be implemented for the DID scheme by using the automatic response playback unit 331. That is, the subscriber database 359 is provided with a list of DID numbers. Of course, the subscriber database 359 stores the identification information of the ring back tone, the identification information of the answering machine and the answering machine sound file, the recording setting value, and the like for each DID number, and the signal controller 500 stores the data. Handle incoming calls accordingly. In the original DID method, the call is directly connected to the terminal by the called number itself without a separate extension number, but when the extension number is input by accessing the representative telephone number using the integrated information providing device according to the present invention, Operate to connect the call. At this time, the signal controller 500 controls the answering machine reproducing unit 331 to guide the extension number when answering the call to the called party number set as the representative number. When the caller inputs the extension number in response to the answering machine, the signal controller 500 detects this from the reception information editing unit and uses the detected extension number to connect a call from the outside to the corresponding extension number. The call setup process is controlled according to a known protocol of the R2 MFC scheme. When call setup is completed, the signal controller 500 connects the call currently being processed to this extension number. In this case, the extension number may be a part of the DID number or may be a number set internally separately. If the number is internally set, this value may be stored in the subscriber database 359.

In the present exemplary embodiment, an automatic response recorder 333 may be further provided to receive the automatic answering sound source for each called number and store it in the automatic answering sound source database 339. Accordingly, it is possible to freely change the auto reply message. For example, when the administrator client requests a change of the answering machine through the network connection unit 930, the communication server 910 receives the request and provides the request to the answering machine 333. When the administrator client uploads the answering machine file from a specific directory of his computer, the file is stored in the answering machine sound source database 339 in place of the answering machine set by the answering machine recorder 333.

According to an additional aspect, in one embodiment, the call manager 373, in response to a request from the client, is configured to absent the corresponding party number by the absence manager 3731 and the information collector 371. If it is detected that the call is requested to the set called number, the call is connected to the answering machine replay unit 331, and the control is made to play and provide the missed sound source, and the call message is received through the communication server to the set missed contact number. The notification unit 3731 may include a notification.

For example, a user selects an out-of-office setting menu from a client program menu according to the present invention executed in his computer, sets an out-of-office, and further selects an SMS notification function. This setting state is received by the communication server 910 through the network connection unit 930 and transmitted to the member manager 3735. The absence manager 3735 stores the out of office setting in the subscriber database 359. The subscriber database 359 stores and manages mobile communication terminal numbers that can be missed for each subscriber. When the call setup request is made to the subscriber, the signal controller 500 checks this in the subscriber database 359 and informs the notification unit 3731 of the corresponding information. The notification unit 3731 is a mobile communication terminal number received by the signal control unit 500. The notification unit 3731 adds caller information detected by the information collection unit 371 to the reception information editing unit 130. Create and send a text message to indicate that you are coming. This text message transmission request is sent to the messaging system of the mobile carrier, for example, which handles the text message sending at the communication server 910.

According to another characteristic aspect of the invention, the ring back tone and / or answering machine may be updated from a telephone terminal connected to the extension. According to this aspect, the integrated information device is configured to respond to a request from an extension terminal for an extension line 711 for establishing a voice call path with the requested terminal, and for inputting a voice to the extension point 711 when a call is established. The apparatus may further include a sound source generator 731 for generating a sound source by encoding a set portion of the signal.

In this case, when the call is connected to the extension connection unit 711, the signal controller 500 controls the answering machine to play by answering the answering machine set in the answering machine 331, and responds to the sound source generated by the sound source generator. The response recorder 333 may be provided. In another embodiment, when a call is connected to the extension connection unit 711, the signal controller 500 controls to respond by replaying the answering source set in the answering machine reproducing unit 331, and in the sound source generating unit The generated sound source may be provided to the ringback tone recorder 313. The signal controller 500 may selectively provide the sound source file generated by the sound source generator 731 to the automatic response recorder 333 or the ringback tone recorder 313 according to a code input by the user in the automatic response process. For example, an administrator can call a specific extension and modify the ring back tone or answer line.

Hereinafter, a method of processing a received call according to the present invention will be described. According to a preferred embodiment of the present invention, a call processing method for responding to a call incoming at a front end to a digital trunk line type private exchange is described with reference to FIG. 3 is a flowchart schematically illustrating a call processing method according to an exemplary embodiment of the present invention. As shown, the call processing method according to the present embodiment is first started by the calling terminal dialing and requesting call establishment through the public network to the called terminal (step S101). In response to this request, the local exchange of the public network issues a call setup request signal to the private exchange (step S301). This call setup request signal includes phone number information of the called terminal. The integrated information providing apparatus receives this signal and detects the called number while relaying to the private exchange side. Since the called number is a DID type number, the extension number can be known. As the protocol for call setup proceeds, the local exchange transmits an alarm signal to the private exchange (step S303), and the private exchange supplies a ringing current to ring the called terminal in response to this signal (step S701). At this time, the integrated information providing device detects the caller phone number included in the alert signal. In one embodiment, the detected called and called numbers are stored and managed in the call database 379. The call database 379 manages the caller, the called party, the call start time, and the call end time as a database. The call start time and call end time are checked by monitoring the call establishment protocol between exchanges. If the called terminal does not answer because it is missed, the call is managed as missed.

Next, the ringback tone signal is sent from the private exchange in response to the call establishment request (step S501). The integrated information providing apparatus detects this signal, blocks the ringback tone signal from being transmitted to the local exchange side, edits the ringback tone signal, inserts the ring back tone instead of the ringback tone signal, and transmits it to the local exchange side (step). S305). This signal is fed to the calling terminal. The ring back tone may be set for each called party number. In addition, the ring back tone may be set differently according to the calling party number. For example, if the call is from a VIP customer, a special comment may be provided.

Thereafter, when the user of the called terminal responds to the ring (step S703), a response signal is generated and sent from the private exchange side (step S503). The integrated information providing apparatus detects this response signal and stops transmitting the ring back tone, and transmits the received response signal to the local exchange to connect the call (step S503). If the telephone is terminated after the receiver is set down at the calling terminal or the called terminal (step S103), a call release request signal is issued at the corresponding local exchange or private exchange (step S307). Accordingly, the local exchange and the private exchange proceed with the protocol for call release to terminate the call.

According to a characteristic aspect of the present invention, when a response signal is transmitted from the private exchange side and the integrated information providing apparatus detects this (step S503), the call path is connected and call recording is started (step S503). In addition, if the call release protocol is advanced between the local exchange and the private exchange (step S307), it is detected and the recording is terminated (step S507). Since the present invention analyzes the protocol between the exchanges and controls the recording timing, it is possible to start or end the recording of the call history without any user manipulation.

4 is a flowchart schematically showing a call processing method according to another preferred embodiment of the present invention. This embodiment relates to a case where a call is received at a DID number set as a representative number connected to an extension number by an auto answer. As shown, the call processing method according to the present embodiment is first started by the calling terminal dialing and requesting call establishment through the public network to the called terminal (step S101). In response to this request, the local exchange of the public network issues a call setup request signal to the private exchange (step S301). This call setup request signal includes phone number information of the called terminal. When the integrated information providing device detects this signal and confirms that the number is set as the representative number, it sets up a call path with itself according to a general call setting protocol in response to this call, and provides an automatic reply message using the set call path. (Step S304). In this automatic answering process, the incoming extension number is received from the caller and detected. The DID number of the called terminal is obtained from the extension number. This extension number itself may be a DID number or may be obtained by a lookup table that defines the relationship between the extension number guided by the auto-answer and the actual DID number.

Thereafter, the integrated information providing apparatus processes a call establishment process between the private exchange and the called terminal having the obtained DID number. That is, the call setup request signal including the obtained DID number is first transmitted to the private exchange (step S501).

Thereafter, in step S303, an alarm signal including the originating phone number obtained from the alarm signal received from the local exchange is generated by itself and provided to the private exchange (step S503). In one embodiment, the detected called and called numbers are stored and managed in the call database 379. The call database 379 manages the caller, the called party, the call start time, and the call end time as a database. The call start time and call end time are checked by monitoring the call establishment protocol between exchanges. If the called terminal does not answer because it is missed, the call is managed as missed.

As a result, the private exchange provides a ringing current to the terminal having the corresponding DID number to ring the ring (step S701). At this time, the private exchange sends a ringback tone signal (step S501). The integrated information providing apparatus detects the ringback tone signal, blocks the ringback tone signal from being transmitted to the local exchange side, edits the ringback tone signal, inserts the ring back tone instead of the ringback tone signal, and transmits the ringback tone signal to the local exchange side. (Step S305). This signal is fed to the calling terminal. The ring back tone may be set for each called party number. In addition, the ring back tone may be set differently according to the calling party number. For example, if the call is from a VIP customer, a special comment may be provided.

Thereafter, when the user of the called terminal responds to the ring (step S703), a response signal is generated and sent from the private exchange side (step S503). The integrated information providing apparatus detects this response signal and stops transmitting the ring back tone, and transmits the received response signal to the local exchange to connect the call (step S509). If the telephone is terminated after the receiver is set down at the calling terminal or the called terminal (step S103), a call release request signal is issued at the corresponding local exchange or private exchange (step S307). Accordingly, the local exchange and the private exchange proceed with the protocol for call release to terminate the call.

According to a characteristic aspect of the present invention, when the response signal is transmitted from the private exchange side and the integrated information providing apparatus detects this (step S503), the call path is connected and call recording is started (step S511). In addition, if a call release protocol is performed between the local exchange and the private exchange (step S307), it is detected and the recording is terminated (step S513). Since the present invention analyzes the protocol between the exchanges and controls the recording timing, it is possible to start or end the recording of the call history without any user manipulation. In addition, it is possible to set a representative phone number for a DID-type private exchange and connect a call to an extension number through an auto answer.

As described in detail above, a user who uses a private exchange by using the integrated information providing apparatus according to the present invention, regardless of whether a service provider provides a service in a current system, instead of ringback tone, the service provider may use music, advertisement, It is possible to freely provide a ring back tone such as voice mement. In addition, even if the calling party number is not displayed on the private exchange or the general extension telephone accommodated in the exchange, the calling party number can be detected and stored without inserting a separate card in the private exchange and can be confirmed through a computer network.

Furthermore, through the integrated information providing apparatus according to the present invention, not only the systematic management of the call history is possible but also the computer according to the present invention can manage the recording and recording using the apparatus according to the present invention without a separate system.

In addition, the integrated information providing apparatus according to the present invention can implement a function provided by inserting only a digital board on which a reception information editing unit and a transmission information editing unit are implemented in a known server computer and mounting software, thereby providing a very inexpensive and flexible system. It is possible.
