Description

  The present invention relates to an IP (Internet Protocol) telephone, and more particularly to an incoming operation of an IP telephone apparatus.

  In a conventional IP telephone apparatus, when responding to an incoming call from the IP network, it is necessary for the user of the IP telephone apparatus to perform some kind of response operation such as raising the handset or pressing a button. Such a response operation is very easy for a healthy person, but may be difficult for a physically handicapped person such as a bedridden person.

  If it is an IP telephone device that automatically responds to all incoming calls, no response operation is required, but in this case, even incoming calls that do not need to be answered will be answered. The customer's convenience will be impaired.

  For this reason, there is a need for an IP telephone device that performs a response operation that differs for each caller.

  However, from the standpoint of the caller side, if the caller makes a call to an IP telephone device that performs different response operations depending on the situation, the caller performs what kind of response operation the called phone device performs. I don't know. For this reason, it may be difficult for the caller to return an appropriate response to the automatic response on the called side.

  Japanese Patent Application Laid-Open No. 2004-228561 describes a conventional technique relating to an automatic response in a telephone device of a circuit switching network.

JP 2001-136238 A

  The present invention has been made in view of such a situation, and a problem to be solved by the present invention is to provide an IP telephone technology for executing a response operation in an appropriate mode according to a caller.

  Another problem to be solved by the present invention is to provide an IP telephone technology that notifies a caller of the type of response operation prior to the response operation.

  In view of such circumstances, the present invention proposes the following automatic answering method for IP telephone apparatus, IP telephone apparatus, computer program, and IP telephone system.

  First, according to the present invention, in a method in which an IP (Internet Protocol) telephone device automatically responds, the IP telephone device responds to reception of an INVITE message from the address of the calling terminal subject to automatic response. A setting storage stage in which a response operation type to be performed after the session is automatically established is associated and stored in the storage device as an automatic response setting, and the IP telephone device receives the INVITE message from the calling terminal via the IP network The INVITE reception stage, the address verification stage in which the IP telephone apparatus receives the address of the calling terminal received together with the INVITE message with the address included in the automatic response setting, and the calling address is set to the automatic response setting in the address verification stage. When included, the predetermined off-hook at the human I / F of the IP telephone device A session establishment stage in which the IP telephone device establishes a session with the calling terminal without waiting for an operation, and a response according to the response operation type associated with the address of the calling terminal in the automatic response setting The present invention proposes an automatic answering method for an IP telephone device, which includes a response stage in which the IP telephone device performs an operation.

  As the response action type, for example, a voice call response and a hands-free response can be considered.

  In the voice call response, the IP telephone device includes an external speaker that outputs voice in the vicinity, and stores an automatic response setting including a voice call response as a response operation type in the storage device in the setting storage step. As an operation corresponding to the voice call response, the voice transmitted from the calling terminal is output from the external speaker.

  In the hands-free response, the IP telephone apparatus includes an external speaker that outputs voice to the periphery and an external microphone that inputs the peripheral voice, and an automatic response setting including a hands-free response as a response operation type at the setting storage stage. Is stored in the storage device, and at the response stage, the voice received from the calling terminal is output from the external speaker and the voice input from the external microphone is transmitted to the calling terminal as an operation according to the hands-free response. .

  Prior to session establishment, it is desirable to notify the calling terminal of the response action type. In this case, the IP telephone apparatus receives the INVITE message via a predetermined server apparatus, the IP telephone apparatus transmits an automatic response setting to the server apparatus, and the server apparatus stores the IP telephone apparatus and the automatic response setting in association with each other. In response to the reception of the INVITE message to be transferred to the IP telephone apparatus, the server refers to the automatic response setting stored in association with the IP telephone apparatus and notifies the calling terminal of the corresponding response operation type. At this time, it is desirable that the calling terminal outputs the notified response action type at the output device.

  In the IP telephone apparatus, the address of the calling terminal that is the target of the automatic response is associated with the response operation type that is performed after the session is automatically established in response to reception of the INVITE message from the address. A storage device that stores the automatic response setting, an address verification unit that executes processing for verifying the address of the calling terminal received together with the INVITE message with the address included in the automatic response setting, and the address of the calling terminal is automatically When included in the response setting, session establishment means for executing a process of establishing a session with the calling terminal without waiting for a predetermined off-hook operation at the human I / F of the IP telephone device, and automatic response setting Response means for executing a response action according to the response action type associated with the address of the calling terminal. To propose an IP telephone apparatus according to claim Rukoto.

  Further, the present invention provides a computer program executed by a server device of an IP telephone system, and establishes a session for an address of a calling terminal to be automatically answered by the IP telephone device and an IP incoming call from the address. In response to the INVITE message to the IP telephone device, the automatic response setting associated with the response operation type to be performed later is received from the IP telephone device, the IP telephone device and the automatic response setting are stored in association with each other, A computer program is proposed which refers to an automatic response setting stored in association with an IP telephone device and causes a server device to execute a process of notifying a calling terminal of a corresponding response operation type.

  Furthermore, the present invention proposes a system comprising an IP telephone apparatus and a server apparatus connected via an IP network in an IP telephone system. In this system, the IP telephone device associates the address of the calling terminal that is the target of automatic response with the response operation type that is performed after establishing a session for IP incoming from that address, and stores it as an automatic response setting. When the storage device, the address matching means for executing the process of matching the calling address received together with the INVITE message when receiving the IP with the address included in the automatic response setting, and the calling address are included in the automatic response setting, Session establishment means for executing a process for establishing a session with a calling terminal without waiting for a predetermined off-hook operation by the human I / F of the IP telephone apparatus, and association with a calling address by automatic answer setting Response means for executing a response action corresponding to the response action type being received, and sending the INVITE message to the server device It received through, and transmits an automatic reply set in the server device. In addition, when the server apparatus receives the automatic response setting received from the IP telephone, the server apparatus performs processing to store the automatic response setting in association with the IP telephone apparatus, and stores the automatic response setting in association with the IP telephone apparatus in response to the INVITE message to the IP telephone apparatus. And a processing device that refers to the automatic response setting and performs processing for notifying the calling terminal of the corresponding response action type.

  According to the present invention, when there is an incoming call from an address for which an automatic response is set in advance, the automatic response is made without waiting for the user's off-hook operation. For this reason, it is possible to selectively and automatically respond only to an incoming IP network from a specific caller.

  Further, according to the present invention, as an operation mode of the automatic answering, either a voice call response or a hands-free response can be set for each calling address. You can hear the caller's voice prior to the call. For this reason, the called party obtains not only information on who the calling party is prior to the call, but also information that can be used to estimate the mental state of the calling party, such as the tone of the calling party. I can do it.

  Further, according to the present invention, the state of the automatic answer setting of the called terminal can be notified to the calling terminal before the called terminal actually answers.

  An IP telephone system 100 according to an embodiment of the present invention will be described with reference to FIG. The IP telephone system 100 is a system using SIP (Session Initiation Protocol). An IP telephone apparatus 1 that is a calling terminal is connected to a proxy server 3 that is a SIP server via a LAN (Local Area Network) 2. The LAN 2 is connected to another LAN 5 via the Internet 4. A proxy / presence server 6 that is a SIP server is connected to the LAN 5, and an IP telephone device 7 that is a called terminal receives an incoming call via this server. Hereinafter, the IP telephone apparatus 1 may be referred to as a calling terminal, and the IP telephone apparatus 7 may be referred to as a called terminal.

  In IP telephone system 100, when calling, an INVITE message is transmitted from the calling terminal to the called terminal. The header field of the INVITE message includes a From field that stores address information of the calling party, a To field that stores address information of the called party, and a Contact field that stores contact address information of the calling party. SIP servers, such as a proxy server and a redirect server, route calls by referring to the values stored in these fields during the call setting process.

  Prior to the incoming call, the user of the called terminal 7 registers settings relating to the automatic response, absence response, and incoming call rejection for the called terminal 7.

  The automatic answer setting is information in which a transmission address for performing a voice call response or a hands-free response is set. Here, the address is identification information of the telephone device such as a SIP URL (Uniform Resource Locator) of the IP telephone device or a telephone number of a PSTN (Public Switched Telephone Network).

  When an incoming call is received from an address for which a voice call response is set, the called terminal 7 establishes a session without waiting for the user's off-hook operation, activates an external speaker, and receives the voice from the calling terminal. Output to around 7. The voice from the calling terminal has the same function as the ringing tone, and has the function of telling the user who the caller is by voice.

  On the other hand, when an incoming call is received from an address for which a hands-free response is set, the called terminal 7 establishes a session without waiting for the user's off-hook operation, activates the external speaker, and receives the voice from the calling terminal. In addition to outputting to the periphery of the call terminal 7, the external microphone is activated to acquire the sound around the called terminal 7, and transmitted to the calling terminal via the established session.

  The automatic response setting is as shown in Table 1, for example. Table 1 associates and stores the SIP URL (Uniform Resource Locator) of another telephone device and the type of response operation to the incoming call from that SIP URL (separate voice call / hands-free response).

  The answering machine setting is information in which a transmission address for answering by answering machine is set. When there is an incoming call from the corresponding address, the called terminal 7 establishes a session without waiting for the user's off-hook operation, transmits a message notifying the absence of the user to the calling terminal, and then receives the voice from the calling terminal. Record.

  The incoming call rejection response setting is information in which a transmission address for ignoring incoming calls is set. When there is an incoming call from the corresponding address, the called terminal 7 ignores the incoming call without making a ringing tone or the like.

  As shown in FIG. 2, the called terminal 7 in which the automatic response setting is registered (step S1) notifies the proxy / presence server 6 of the content of the automatic response setting (step S2). There are a plurality of IP telephone apparatuses on the LAN 5 that perform IP telephones via the proxy / presence server 6. The proxy / presence server 6 stores the contents of the automatic response settings of each of the plurality of IP telephone devices in association with the address of the IP telephone device (step S3). Table 2 is an example of this association. In Table 2, the SIP URL of the called terminal 7 is suzuki @ aaa. aaa. aaa and the SIP URL of the IP telephone device (not shown) other than the called terminal 7 under the proxy / presence server 6 is nakamura @ hh. hhh. hh. As can be seen by comparing Table 1 and Table 2, Table 2 stored in the proxy / presence server 6 has a structure including Table 1 stored in the called terminal 7.

  Next, the operation of IP telephone system 100 when making a call from calling terminal 1 to called terminal 7 will be described. First, an operation when the response operation type set in the automatic response setting is a voice call response will be described with reference to FIG. The SIP URL of the calling terminal 1 is yamamoto @ bbb. bbb. Let bbb.

  When the calling terminal 1 transmits an INVITE message to the proxy server 3 (step S10), the proxy server 3 that has received the INVITE message, from the To field of the header, suzuki @ aaa. aaa. Read aaa and its domain aaa. aaa. The INVITE message is transferred to the proxy / presence server 6 which is an aaa proxy server (step S11), and TRYING notifying that the current request is being executed is returned to the calling terminal 1 (step S11). S12).

  The proxy / presence server 6 that has received the INVITE message reads the address from the To field, and transfers the INVITE message to the called terminal 7 having the corresponding address (step S13). In addition, the SIP URL yamamoto @ bbb. bbb. bbb is read, and it is determined with reference to Table 2 whether or not an automatic response is set for this address. Referring now to Table 2, the called SIP URL is suzuki @ aaa. aaa. aaa and the calling SIP URL is yamamoto @ bbb. bbb. Since bbb, the voice call response is set as the automatic response setting. In this case, the proxy / presence server 6 notifies the proxy server 3 of a voice call response as a response operation type together with the address of the calling terminal 1 (step S14).

  Receiving the notification of the response operation type from the proxy / presence server 6, the presence server 3 notifies the calling terminal 1 of the response operation type (step S15). Receiving this, the calling terminal 1 notifies the caller who is the user of the response action type, in this case, the voice call, on the display device or the like (step S16). At this stage, the calling party can know that the automatic answering setting has been made in the called terminal 7 and that the set response action type is a voice call. Thus, the calling party can prepare to call the called party after the subsequent session is established.

  On the other hand, the called terminal 7 that has received the INVITE message from the proxy / presence server 6 in step S13 returns OK to the calling terminal 1 (steps S17, S18, S19). Upon receiving this, the calling terminal 1 returns an ACK to the called terminal (step S20), and a session is established between the calling terminal 1 and the called terminal 7 (step S21).

  After the session is established, the called terminal 7 transmits to the calling terminal 1 guidance for prompting the calling party to call the called party with his / her own voice or the like (step S22). The called terminal 7 activates the external speaker and outputs the sound transmitted from the calling terminal 1 toward the periphery (step S23). At this time, the external microphone is not activated.

  In response to the display of the response operation type in step S16 and the guidance message in step S23, the calling party calls the called party with a voice such as a real voice (step S24). In response to this, when the called party performs a predetermined off-hook operation (step S25), the called terminal 7 activates the external microphone while activating the external speaker to realize a hands-free call, or While the external speaker is deactivated, the microphone and the speaker of the receiver are activated (step S26), thereby realizing a call using the receiver (step S27).

  Next, with reference to FIG. 4, an operation when the response operation type set in the automatic response setting is a hands-free response will be described. The SIP URL of the calling terminal 1 is Takahashi @ ddd. ddd. It is set as ddd.

  Steps S10 to S13 are substantially the same as those in the case of the voice call response described above except for the difference in the address of the calling terminal 1.

  The proxy / presence server 6 that has received the INVITE message transfers the INVITE message in step S13 and reads the address of the calling terminal 1 from the From field. The SIP URL of the calling terminal 1 at this time is Takahashi @ ddd. ddd. ddd. Referring to Table 2, the called SIP URL is Suzuki @ aaa. aaa. aaa and the calling SIP URL is Takahashi @ ddd. ddd. Since it is ddd, a hands-free response is set as the automatic response setting. In this case, the proxy / presence server 6 notifies the calling terminal 1 of a hands-free response as the response operation type together with the address of the calling terminal 1 via the proxy server 3 (steps S30 and S31).

  The calling terminal 1 that has received the notification notifies the calling party by displaying on the display device that the response action type is a hands-free response (step S32).

  Steps S <b> 17 to S <b> 21 are substantially the same as those in the case of the voice call response described above except for the difference in the address of the calling terminal 1.

  When the session is established in step S21, the called terminal 7 transmits guidance for notifying the caller that the response is a hands-free response (step S33) and activates both the external microphone and the external speaker. (Step S34) to implement a two-way call (Step S35).

  Next, the IP telephone apparatus 7 as a called terminal will be described with reference to FIG.

  An IP line interface (I / F) 71 is an interface device that connects the IP telephone device 7 and the LAN 5, and performs processing related to the IP protocol and codec processing.

  The human interface (I / F) 72 includes a handset, an external speaker, an external microphone, a display unit, a numeric keypad, a setting button, and the like, and performs an input operation by the user, input / output of voice, and display of information to the user. The external speaker is a speaker that outputs sound around the IP telephone device 7. The external microphone is a microphone for inputting voice around the IP telephone device 7.

  The control unit 73 is a processing device including a processor, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and controls the operation of the IP telephone device 7.

  The setting storage unit 74 is a rewritable memory device such as a flash memory, for example, and stores setting information related to automatic response, absence response, and incoming call rejection.

  The hands-free / voice call control unit 75 refers to the automatic response setting stored in the setting storage unit 74 so that when there is an incoming call from the corresponding address, the human I / F 72 executes a predetermined response operation. Control.

  The guidance output unit 76 performs processing for transmitting a guidance message stored in advance in the transmission guidance accumulation unit 77 to the transmission terminal.

  The transmission guidance accumulating unit 77 stores a guidance message to be transmitted to the calling terminal at the time of a voice call response, a hands-free response, or an answering response.

  The voice recording unit 78 performs a process of recording the voice message received from the calling terminal during the absence response in the recording storage unit 79.

  The ringing tone output unit 80 uses an external speaker of the human I / F 72 to make a bell sound or the like when an incoming call is received from an address that does not correspond to any of a voice call response, a hands-free response, an absence response, and an incoming call rejection response. The user is notified of an incoming call by ringing a predetermined ringing tone.

  Next, the incoming call operation of IP telephone apparatus 7 will be described with reference to FIG. Prior to the incoming call, it is assumed that the user of the IP telephone device 7 has already set the automatic response setting, the absence response setting, and the incoming call rejection setting via the human I / F 72.

  When the INVITE message is received from the proxy / presence server 6 via the IP line I / F 71 (step S41), the control unit 73 acquires the calling address from the From header field of the INVITE message, and the voice is transmitted to the address. Whether or not a call response or a hands-free response is set is determined with reference to the automatic response setting stored in the setting storage unit 74 (step S42). If either one is set, an automatic response described later is performed (step S43).

  If not set, the control unit 73 refers to the answering response setting stored in the setting storage unit 74, and determines whether or not an answering response is set for the calling address (step). S44).

  In the case of an incoming call from an address for which an answering response is set, the control unit 73 establishes a session via the IP line I / F 71 (step S45) and sends out an answering response guidance to the guidance output unit 76. Is instructed to do so (step S46). The guidance output unit 76 reproduces the voice message data for absence response guidance stored in advance in the transmission guidance storage unit 77, and transmits it as a voice to the calling terminal 1 via the IP line I / F 71 (step S46). Further, the control unit 73 instructs the voice recording unit 78 to record the voice input from the calling terminal 1. The voice recording unit 78 stores the voice input via the IP line I / F 71 in the recording storage unit 79 (step S47).

  In the case of an incoming call from an address for which no answering is set, the control unit 73 refers to the incoming call rejection setting stored in the setting storage unit 74 and is the incoming call rejection set for the outgoing call address? It is determined whether or not (step S48). In the case of an incoming call from an address for which incoming call rejection is not set, the control unit 73 instructs the ringing tone output unit 80 to ring the ringing tone (step S49). When a predetermined off-hook operation is performed on the human I / F 72, the control unit 73 establishes a session with the calling terminal 1 (step S51). On the other hand, if incoming call rejection is set, the control unit 73 does nothing and ignores the INVITE message.

  Next, the automatic response in step S43 will be further described with reference to FIG.

  In the case of an incoming call from an address for which automatic response setting is set, the control unit 73 establishes a session with the calling terminal 1 (step S61). When the response operation type set for the call address is a voice call response, the control unit 63 instructs the guidance output unit 76 to reproduce the voice guidance data for the voice call response. In response to this, the guidance output unit 76 reads out and reproduces the corresponding voice guidance data from the transmission guidance storage unit 77, transmits it to the calling terminal 1 via the IP line I / F 71 (step S63), and human I. The external speaker of / F72 is activated (step S64), and the voice transmitted from the calling terminal 1 is output so that it can be heard around the called terminal 7. When the called party who has heard this performs a predetermined off-hook operation at the human I / F 72 (step S65), the control unit 73 activates the external microphone of the human I / F 72 in response to this, or Talking from the calling terminal 1 to the called terminal 7 and sending from the called terminal 7 to the calling terminal 1 by deactivating the external speaker and activating the speaker and microphone of the handset The two-way call is realized (step S66).

  On the other hand, when the response operation type set for the calling address is a hands-free response, the control unit 63 instructs the guidance output unit 76 to reproduce the voice guidance data for hands-free response. . In response to this, the guidance output unit 76 reads out and reproduces the corresponding voice guidance data from the transmission guidance storage unit 77, transmits it to the calling terminal 1 via the IP line I / F 71 (step S67), and human I. The external speaker and the external microphone of / F72 are activated (step S68).
