Description

  The present invention relates to a telephone communication apparatus that performs an analog call and a digital call.

  With the development of communication network technology, a voice call by a telephone communication device is in addition to an analog call for performing an analog voice signal communication via a public switched telephone network (PSTN). In addition, it is possible to perform a digital call through which digital audio data signal communication is performed based on the Internet protocol (IP) via the Internet. The digital call will be further described. With the development of a digital data communication network such as the Internet, a voice call based on the so-called VoIP (Voice over Internet Protocol) technology has become possible. In this digital call, each other's telephone communication device transmits and receives an audio signal converted into digital data via a digital data communication network. In particular, in recent digital data communication via the Internet, broadbandization has progressed and voice signals converted into digital data can be transmitted and received at high speed, so that sufficient sound quality can be realized even in digital calls. Digital data communication is also relatively easy to multiplex, and physically a plurality of call lines can be accommodated in a single communication cable. Furthermore, xDSL technology such as ADSL (Asymmetric Digital Subscriber Line) can superimpose a high-frequency digital signal on the telephone line used for connection to the PSTN to accommodate an analog telephone line and a plurality of digital telephone lines. ing.

Many telephone communication devices that perform only analog calls have an answering machine function. The answering machine function mainly includes a recording / playback function and an incoming call automatic answering function. Furthermore, the recording / playback function converts an analog audio signal received through an analog call into a DSP (Digital
A recording function for converting into digital data by a signal processor), compressing and storing in a predetermined storage area, and digital audio data stored in the predetermined storage area are expanded by a DSP and converted into an analog audio signal to a speaker. And playback function to output to. The incoming call automatic response function is a function for counting call signals from subscriber exchanges, capturing a line when a predetermined count is reached, and sending a pre-recorded response message to the line. With the incoming call rejection function using the incoming call response function, it is possible to automatically send out a voice message or the like indicating that connection cannot be established for an incoming call from a specific telephone communication device (for example, patents) Reference 1).

  A telephone communication device that performs an analog call and a digital call also has an answering machine function, but complicated control is required. For example, an Internet VoIP adapter that realizes an analog call and an Internet call (digital call) and arbitrarily switches the call path during each call can respond for a certain time from an analog terminal device connected to an incoming analog call. When there is not, it can respond automatically and can switch to incoming IP calls (see, for example, Patent Document 2).

JP-A-3-36861 JP 2003-298738

  As in the incoming call restriction system described in Patent Document 1, if an off-hook is accidentally made while sending a response message by an incoming call automatic response function in an analog call, the sending of the response message is interrupted, and the other party's telephone communication device It becomes possible to talk with. Therefore, since a response message is sent out and a new call cannot be made at the same time, there is a problem that it is inconvenient for the user. The Internet VoIP adapter described in Patent Document 2 can also switch between an analog call and a digital call during a call, but does not disclose any means for making a new call simultaneously with an automatic response.

  An object of the present invention is to provide a telephone communication device having an easy-to-use incoming call automatic response function.

The present invention also includes a determination unit that determines whether an incoming call is an analog call or an incoming digital call,
The message sending means is characterized in that the operation is changed between an incoming call for an analog call and an incoming call for a digital call.

  Further, according to the present invention, the message sending means sends out an incoming call rejection response message by connecting to a line in the case of an incoming analog call, and sends out an incoming call rejection response message or busy tone without connecting to the line in the case of an incoming digital call. It is characterized by.

  According to the present invention, there is provided a telephone communication device for performing an analog call and a digital call. A voice message is stored in a voice memory in advance, and when a predetermined condition is satisfied, the message transmission means This is a telephone communication device having a so-called incoming call response function for sending a voice message to the device.

  The control means detects the operation of the message sending means when the calling means makes a call and controls the operation of the calling means. If the message sending means is sending a voice message in an analog call, the calling means is controlled to make a call in a digital call, and if the message sending means is sending a voice message in a digital call, the analog The calling means is controlled so as to make a call by a call or a digital call.

  This provides a telephone communication device that can make a new call even while sending a voice message to the other party's telephone communication device, and has an easy-to-use incoming call automatic response function can do.

  According to the present invention, the voice message includes an answering message indicating that the user of the telephone communication device is absent, and the message sending means counts the ringing signal received from the exchange and receives a predetermined number. An answering response message is transmitted to the telephone communication device of the other party.

  Thus, an answering machine function can be realized, and a new call can be made even while an answering message is being sent.

  According to the present invention, the telephone number to be rejected is stored in advance in the memory, and the caller identification means receives the outgoing telephone number from the exchange and matches the telephone number stored in the memory. Whether or not an incoming call from a caller whose call is to be rejected is identified.

  The message sending means sends an incoming call rejection response message indicating that the incoming call is rejected to the other party's telephone communication device when the caller identification means identifies the incoming call from the caller whose call is to be rejected. .

  Thereby, an incoming call rejection function can be realized, and a new call can be made even while an incoming call rejection response message is being sent.

  Further, according to the present invention, the determination means determines whether the incoming call is an analog call or a digital call, and the message sending means changes the operation depending on whether the incoming call is an analog call or an incoming digital call. . Specifically, in the case of an incoming analog call, an incoming call rejection response message is sent by connecting to the line, and in the case of an incoming digital call, an incoming call rejection response message or busy tone is sent without connecting to the line.

  As a result, the incoming call rejection response message or the busy tone can be selected and transmitted according to the destination, improving usability. For example, an incoming call rejection message is sent to a party that wants to specifically reject the incoming call, and a busy tone is sent to the other party that cannot be clearly rejected to pretend that the call is in progress. To do. Also, since it takes time and effort to record the incoming call rejection response message and a large amount of storage capacity is required, multiple incoming call rejection response messages are prepared to change the message to be sent according to the destination. Attempting to do so can cause problems. On the other hand, if busy tone is used as one of the messages, it is possible to save time and time for creating and to reduce the storage capacity.

  An embodiment of the present invention will be described by taking a so-called VoIP telephone as an example of a telephone communication apparatus that performs an analog call and a digital call.

  FIG. 1 is a block diagram showing a schematic electrical configuration of a VoIP telephone 100 according to an embodiment of the present invention.

  The VoIP telephone 100 includes a line capture circuit 1, a speech network 2, a switching circuit 3, a handset 4, an external speaker 5, a dial circuit 6, an incoming call detection circuit 7, a caller telephone number reception circuit 8, a memory 9, a display unit 10, and VoIP. A usable light emitting diode (LED) 11, a PSTN LED 12, a VoIP LED 13, an operation panel 14, a DSP 15, an ADSL modem 16, a splitter 17, an audio memory 18, an answering machine DSP 19, and a control unit 30 are included.

  A telephone line 20 is connected to the VoIP telephone 100 and is electrically connected to the PSTN by enabling communication with the exchange. The telephone line 20 is shared by an analog call line and a digital call line, and is used for a so-called ADSL line in which an audio signal for analog call and a data signal for digital call are superimposed. Specifically, the telephone line 20 is a two-wire or four-wire cable and is connected to the RJ-11 connector of the splitter 17. The splitter 17 separates the voice signal for analog call and the data signal for digital call and sends them to a predetermined circuit of the VoIP telephone 100, and the voice signal sent from the predetermined circuit of the VoIP telephone 100. And a superimposing function for superimposing the data signal. A splitter is also provided on the accommodation station side, and the audio signal is sent to the exchange and the data signal is sent to the Internet through the ADSL modem.

The line capture circuit 1 closes or opens the analog communication line by a signal from the dial circuit 6 and notifies the telephone control unit 31 of the state by a signal. The speech network 2 sends a reception signal from the analog line to the switching circuit 3 and transmits a transmission signal from the switching circuit 3 to the PSTN via the analog line, or a DTMF (Dial
Tone Multi Frequency) signal is sent to the line capture circuit 1.

  The switching circuit 3 inputs audio signals from the microphones of the speech network 2 and the handset 4 in accordance with a control signal from the telephone control unit 31, and outputs audio signals to the speakers of the speech network 2, the handset 4 and the external speaker 5. Switch the signal path connection so that Further, the switching circuit 3 receives the speech signal input from the speech network 2, the microphone of the handset 4 and the DSP 15, and the hold sound signal input from the telephone control unit 31 in accordance with the control signal from the telephone control unit 31. The signal path connection is switched so as to output to the speech network 2, the speaker of the handset 4, the external speaker 5 and the DSP 15. Particularly in the case of a three-party call, for example, an audio signal input from the speech network 2 is output to the speaker of the handset 4 and the DSP 15, and an audio signal input from the microphone of the handset 4 and the DSP 15 is output to the speech network 2. Switch the signal path connection.

  The dial circuit 6 opens and closes the line capturing circuit 1 to generate a dial pulse, or outputs a DTMF signal to the speech network 2 to send a transmission signal to the analog line. The incoming call detection circuit 7 detects a CAR signal or an IR signal input from an analog line, and notifies the telephone control unit 31 of the detection of the incoming call. Here, the CAR signal (information receiving terminal activation signal) is a signal sent before notifying the caller's telephone number by the caller's telephone number notification service, and when the telephone receives this signal, Receive a phone number. Further, the IR signal is an incoming ringing signal. Normally, when the telephone receives the IR signal, it rings a ringing tone from the external speaker 5 or the like.

  The caller telephone number receiving circuit 8 receives and demodulates information such as a caller telephone number sent from an analog line, and acquires a caller telephone number that becomes caller identification information. The memory 9 stores a caller telephone number to be rejected, a call history and a call history of an analog call and a digital call, a caller telephone number received by the call answering function, a type of a line used at that time, a destination The phone book data that associates the name or name with a telephone number is stored.

  The VoIP telephone 100 includes a display unit 10 realized by an LCD (Liquid Crystal Display) or the like, and a VoIP usable LED 11, a PSTN LED 12, and a VoIP LED 13 using LEDs as display means. The display unit 10 displays a character string and a pictogram, and notifies the user of various information and messages. The VoIP usable LED 11 lights up when digital communication is possible. The PSTN LED 12 lights up when an analog call is made / received using an analog line. The VoIP LED 13 is lit when a digital call is made or received using a digital line. The operation panel 14 is used to move a dial key for inputting a destination telephone number, a function key for using various functions other than telephone communication such as an answering machine function, and a cursor displayed on the display unit 10. A plurality of keys such as a cursor key and a determination key for determining a command are provided.

  The DSP 5 performs signal processing for converting a digital audio signal sent from the digital line into an analog audio signal, or converting an analog audio signal input from the microphone of the handset 4 into a digital audio signal. The ADSL modem 16 modulates and demodulates the data signal to transmit and receive the data signal using a digital line.

  The voice memory 18 stores the voice of the other party recorded by the recording / playback function of the answering machine function, the response message voice played back by the incoming call response function, and the like. The answering machine DSP 19 records the other party's voice in the voice memory 18 as a digital voice signal, and reproduces the other party's voice recorded in the voice memory 18 and a response voice message as a digital voice signal. The message sending means includes the answering record DSP 19 and the telephone control unit 31.

The operation of the VoIP telephone 100 is controlled by the control unit 30 based on a control program stored in advance. The telephone control unit 31 is a control unit that controls operations such as a telephone communication function and an answering machine function. The data processing control unit 32 controls data writing to the memory 9 and data reading from the memory 9. The display control unit 33 controls screen display of the display unit 10 and lighting / extinguishing of each LED. The operation detection unit 34 monitors the operation panel 14 and, when any key is input, notifies the telephone control unit 31 of the type of the input key. The used line determination unit 35 is a determination unit that determines which one of an analog line and a digital line is used based on the caller telephone number and notifies the telephone control unit 31 of the result. The VoIP control unit 36 performs call control for making a digital phone call and PPP (Point-to-Point).
Protocol) session establishment and authentication processing with the VoIP server. The DSP control unit 37 controls the operation of the DSP 15. The ADSL control unit 38 controls the operation of the ADSL modem 16. The calling means includes a telephone control unit 31 and a VoIP control unit 36. The caller identification means includes a caller telephone number receiving circuit 8 and a telephone control unit 31.

  The answering machine function and incoming call rejection function of the VoIP telephone 100 will be described. As for the answering machine function and the incoming call rejection function, the same processing is performed for both analog calls and digital calls. In addition, when an incoming call is received via an analog line, the analog line is captured. When an incoming call is received via a digital line, the digital line is captured.

  The answering machine function can be realized by combining the automatic incoming call answering function and the recording / playback function. For example, the incoming call automatic answering function counts the ringing signal from the subscriber exchange, etc., captures the line when the predetermined count is reached, and plays the recorded answering message prerecorded by the recording / playback function. Send to the line.

  Furthermore, an incoming call rejection function can be realized by adding a caller identification function. The caller identification function determines whether the call is received from a caller who rejects the call. If the call is from a caller who rejects the call, the line is captured by the automatic call answering function and connected by the recording / playback function. A rejection response message or the like indicating that it cannot be played is reproduced and transmitted to the line.

  FIG. 2 is a flowchart showing an incoming process of an analog call by the VoIP telephone 100.

  In step S1, after receiving the CAR signal, the calling telephone number is received by the MODEM signal. In step S2, the telephone number of the caller who rejects incoming calls registered in advance is compared with the received call telephone number to identify the caller.

  In step S3, it is determined whether or not the received outgoing telephone number matches the registered telephone number. If they match, the process proceeds to step S4, and if they do not match, the process proceeds to step S6. In step S4, the line is captured, a rejection response message stored in advance in step S5 is transmitted, and the process proceeds to step S11.

  In step S6, a call signal is received, and counting of the number of call signals received in step S7 is started. In step S8, it is determined whether the count has reached a predetermined number. If it has reached, the process proceeds to step S9, and if not, the process proceeds to step S12. In step S9, the line is captured and an answering response message stored in advance in step S10 is transmitted. In step S11, the line is disconnected.

  In step S12, it is determined whether the user is off-hooked by lifting the handset 4 or the like. If it is off-hooked, the process proceeds to step S13, and if it is not off-hooked, the process returns to step S8. In step S13, the line is captured, and in step S14, a normal call is made and the process proceeds to step S11.

  The incoming process for the digital call is similar to the flowchart shown in FIG. 2, but in the case of an analog call, when the incoming call is rejected, the line is captured in step S4 and then a rejection response message is sent in step S5. On the other hand, in a digital call, the line is not captured, that is, the operation of step S4 is not performed, and a rejection response message or a busy tone is transmitted in step S5. Except for the operation related to call rejection, the same operation as the analog call is performed.

  Note that the user can select whether to send a rejection response message or a busy tone by operating the VoIP telephone 100 or the like. For example, the user selects from a setting to always send a rejection response message when an incoming call is rejected, a setting to always send a busy tone when an incoming call is rejected, or a setting to send a rejection response message or a busy tone according to the calling telephone number.

  For example, an incoming call rejection message is sent to a party that wants to specifically reject the incoming call, and a busy tone is sent to the other party that cannot be clearly rejected to pretend that the call is in progress. By doing so, usability of the VoIP telephone 100 is improved. Also, since it takes time and effort to record the incoming call rejection response message and a large amount of storage capacity is required, multiple incoming call rejection response messages are prepared to change the message to be sent according to the destination. Attempting to do so can cause problems. On the other hand, if busy tone is used as one of the messages, it is possible to save time and time for creating and to reduce the storage capacity.

  In a conventional VoIP telephone, if an answering machine function and an incoming call rejection function are activated when an incoming analog call is received, a new call cannot be made while a response message is being sent to capture the line. If an off-hook operation is performed while a response message is being sent to make a call, the call state is shifted to the telephone to which the response message is sent. In contrast, the VoIP telephone 100 of the present invention can make a new call even while a response message is being sent.

  When the telephone control unit 31 is off-hooked, the telephone control unit 31 detects the operating state of the answering machine DSP 19. When the answering machine DSP 19 is operating, that is, when a response message is transmitted, a new call is made without making a call with the other party telephone to which the line is currently connected. In particular, when the connected line is an analog line, an analog call cannot be made, so that a digital call is made. When the connected line is a digital line, an analog call or a digital call is made.

FIG. 3 is a flowchart showing call processing by the VoIP telephone 100.
In step S21, when an off-hook is detected by the user lifting the handset or the like, in step S22, the telephone control unit 31 determines whether or not the line is connected based on the operating state of the answering machine DSP19. If the line is connected, the process proceeds to step S23, and if not connected, the process proceeds to step S25. In step S23, it is determined whether the line to which the incoming call detection circuit 7 is connected is an analog line. If it is an analog line, the process proceeds to step S24, and if it is not an analog line, that is, if it is a digital line, the process proceeds to step S25.

  In step S24, the telephone control unit 31 makes a call by digital call. In step S25, the telephone control unit 31 determines whether to make a call by analog call. If the call is made by analog call, the process proceeds to step S26. If the call is not made by analog call, that is, if the call is made by digital call, step S24 is performed. Proceed to In step S26, the telephone control unit 31 makes a call by analog call.

  In step S25, for example, a telephone number dialed by the user at the time of calling is used as an element for determining whether or not to make an analog call. A telephone number for making an analog call is stored in the memory 9 in advance, and when dialed by the user, the telephone control unit 31 uses the contents stored in the memory 9 and the input telephone number. Determines whether to make an analog call.

  The contents stored in the memory 9 may be basic contents such that special numbers such as 110 and 119 make an analog call, and other general telephone numbers make a digital call. It may be the content that selects analog call or digital call for each number and shows the selection result.

  As described above, it is possible to provide a telephone communication device that can make a new call and has an easy-to-use incoming call automatic response function even during transmission of a response message by an answering machine function and an incoming call rejection function. Can do.
