  By the way, if the IP telephone service is subscribed to the service, it can receive the service anywhere in the Internet connection environment. The IP telephone terminal periodically performs registration operation using an IP address with respect to an IP telephone server that provides an IP telephone service. At this time, if the mobile terminal and the fixed telephone terminal try to use the same IP telephone service with the same telephone number, if the mobile terminal and the fixed telephone terminal register with the IP telephone server, the mobile terminal and the fixed telephone terminal are fixed on the mobile terminal side. When the user ID and password on the telephone terminal side are correct, the IP telephone server operates with the terminal registered later as valid.

  For this reason, when an incoming call occurs, the IP telephone server notifies the terminal registered at that time of the incoming call, so for example, it is known that the user has a call from a certain destination. Sometimes, even if you want to receive the incoming call on the go (mobile terminal side), if the incoming call occurs while the fixed telephone terminal side is enabled, the incoming call may be notified to the fixed telephone terminal side. The mobile terminal cannot reliably answer the incoming call. In other words, in the existing basic IP telephone service, if double registration is performed with different IP addresses, an incoming call notification is made to a terminal having an IP address registered later. There was a problem that it could not be used beyond the base.

  The present invention has been made to solve the above-described problems. For example, when the same telephone number is used for the IP telephone service in the mobile terminal and the fixed telephone terminal, the user does not perform complicated settings. An object of the present invention is to provide an IP telephone system, a telephone apparatus, and a program that can respond to an incoming call at a terminal on a desired side.

  In order to solve the above-described problem, the IP telephone system according to the first aspect of the present invention provides an IP telephone service in which the first telephone apparatus and the second telephone apparatus have the same telephone number by periodic registration with the IP telephone server. When the first telephone device transmits a proxy registration request to the second telephone device, the second telephone device that has received the proxy registration request is: When the IP telephone server sends a registration request to the IP telephone server instead of the first telephone apparatus, and the IP telephone server receives the registration request, the second telephone apparatus The second telephone device that has received the incoming notification transmits the incoming notification to the first telephone device, and the first telephone device responds to the incoming call. To do.

  A telephone apparatus according to a second aspect of the present invention is a telephone apparatus that can use a telephone service with the same telephone number as another telephone apparatus by periodic registration with an IP telephone server, and from the other telephone apparatus When the proxy registration request is received, the registration request is transmitted to the IP telephone server on behalf of the other telephone device. When the incoming call is received for the telephone number and the incoming call notification is received from the IP telephone server, the other telephone apparatus A control unit that transmits the incoming call notification to the telephone device.

  A telephone apparatus according to a third aspect of the present invention is a telephone apparatus that can use an IP telephone service with the same telephone number as another telephone apparatus by periodic registration with an IP telephone server, and the other telephone apparatus The other telephone device sends a registration request to the IP telephone server on behalf of itself, and then receives an incoming call to the telephone number and receives from the IP telephone server. A control unit that waits for reception of an incoming call notification transmitted from the other telephone device that has received the notification and responds to the incoming call;

  A program according to a fourth aspect of the present invention is a program for a telephone device that is executed by a computer and can use a telephone service with the same telephone number as other telephone devices by periodic registration with an IP telephone server, When the computer receives a proxy registration request from the other telephone device, the computer transmits a registration request to the IP telephone server on behalf of the other telephone device; When an incoming call notification is received from a telephone server, a process of transmitting the incoming call notification to the other telephone device is executed.

Note that the same numbers are assigned to the same elements throughout the description of the present embodiment.

(Configuration of the embodiment)
In FIG. 1, the IP telephone system 1 includes a telephone device 10 according to the present embodiment, a mobile terminal 20 such as a mobile phone, and an IP telephone server 30. The telephone device 10 is, for example, a business phone including a main device 11 that controls a plurality of external lines and extensions in common and a plurality of fixed telephone terminals (child devices 12) accommodated in the main device 11. The IP telephone server 30 is an exchange compatible with IP, and uses, for example, RTP (Real-time Transmission Protocol) to packetize voice and connect the telephone apparatus 10 and the mobile terminal 20 connected to the IP network 40. Make a call with. In addition, the mobile terminal 20 shown here demonstrates as what has the same telephone number as the telephone apparatus 10 which concerns on this embodiment.

  FIG. 2 shows an operation sequence diagram of the IP telephone system 1 shown in FIG. The schematic operation of the IP telephone system 1 of FIG. 1 will be described below with reference to the operation sequence diagram of FIG. Note that call control related to commands and responses described below is realized by SIP (Session Initiation Protocol).

  First, when the application is activated, the mobile terminal 20 makes a proxy registration request to the IP telephone server 30 to the telephone device 10 (main device 11) that accommodates the fixed telephone terminal 12 (step S11). The mobile terminal 20 transmits the proxy registration request and obtains an OK response from the telephone device 10 (step S12), and then ends the application. The above-described proxy registration request is shown as “a. Proxy registration request” in FIG.

  On the telephone device 10 side, by receiving a proxy registration request from the mobile terminal 20, a registration request is made to the IP telephone server 30 as a proxy (step S13). The above proxy registration is shown as “b. Proxy registration” in FIG. After receiving an OK response from the IP telephone server 30 (step S14), when an incoming call occurs, the IP telephone server 30 notifies the registered telephone device 10 of the incoming call (step S15). When receiving the incoming call notification, the telephone device 10 notifies the mobile terminal 20 of the incoming information using the push function (step S16).

  The mobile terminal 20 that has received the incoming call notification makes an OK response to the telephone device 10 (step S17), makes a registration request to the IP phone server 30 by starting the application (step S18), and receives an OK response from the IP phone server 30. Is obtained (step S19). The above registration is indicated as “c. Registration” in FIG. Note that the “push function” is to activate a process (application) corresponding to an event when the mobile terminal 20 receives an event, and the mobile terminal 20 uses this function to obtain some information. When there is an update, it is possible to know the update without user interaction. When the IP address of the mobile terminal 20 is registered in the IP telephone server 30, the incoming notification from the IP telephone server 30 is switched to the mobile terminal 20 side. Thus, the incoming call that has occurred can be received by the mobile terminal 20.

  When an incoming notification is sent from the IP telephone server 30 to the mobile terminal 20 (step S20), the mobile terminal 20 performs a message response indicating that the incoming call has been accepted (step S21), and performs call processing such as ringing a bell. (Step S22). As a result, the incoming call can be answered, and when the incoming call is answered, it is notified that the incoming call has been answered (step S23). The user can pause the mobile terminal 20 from when the mobile terminal 20 transmits a proxy registration request to the telephone device 10 until an incoming call is received and the incoming call notification is received from the telephone device 10. (There is no need to always start the application), so it is possible to save battery power.

  Further, the mobile terminal 20 can stop the incoming call notification from the telephone device 10 by canceling the proxy registration request to the telephone device 10 (step S24). When the cancellation of the proxy registration request is received, the telephone device 10 responds to an incoming call from the IP telephone server 30. Further, when the telephone device 10 receives an incoming call notification from the IP telephone server 30 in a state where the proxy registration request is valid (step S25), the mobile terminal 20 performs the incoming call notification using the push function. If the incoming notification is not received due to out of service area (step S26), or the user does not want to respond to the incoming notification from the telephone device 10 at the mobile terminal 20 (step S27), the incoming call from the telephone device 10 is received. By not returning an incoming call response to the notification or not returning an incoming call response, the telephone device 10 can respond to the incoming call without responding to the incoming call at the mobile terminal. On the telephone device 10 side, when there is no response from the mobile terminal 20 within a predetermined time, the incoming call response is made on the telephone device 10 side.

  That is, when an incoming call occurs, the IP telephone server 30 notifies the telephone device 10 of the incoming call (step S28), but the telephone device 10 does not perform the incoming call notification to the mobile terminal 20 (step S29). Here, the telephone device 10 may notify the mobile terminal 20 that the incoming call has been received by the telephone device 10. Accordingly, the telephone device 10 performs a message response indicating that the incoming call has been accepted to the IP telephone server 30 (step S30), performs a calling process such as ringing a bell (step S31), and performs an incoming call response (step S32). ).

  Note that the telephone device 10 selects whether or not the user of the mobile terminal 20 receives a call by notifying the mobile terminal 20 of the caller's telephone number when making an incoming call notification using the push function. Alternatively, it may be set so as to determine whether or not to automatically answer the incoming call based on the telephone number. By controlling in this way, it is possible to distribute incoming calls to a terminal on the side desired by the user even if each device is not linked.

(Operation of the embodiment)
Hereinafter, operations of the mobile terminal and the telephone device according to the present embodiment will be described in detail with reference to the flowcharts of FIGS. 5, 6, and 7.

  According to FIG. 5, when the application is started (step S101), the control unit 201 of the mobile terminal 20 transmits a proxy registration request for the IP telephone server 30 to the main apparatus 11 that accommodates the fixed telephone terminal 12. (Step S102). Then, after obtaining an OK response from the telephone device 10, the mobile terminal 20 ends the application, enters a sleep state (step S103), and waits for an incoming call notification or outgoing call (step S104).

  On the telephone device 10 side, by receiving a proxy registration request from the mobile terminal 20, the IP phone server 30 makes a proxy address registration request to the IP phone server 30. Therefore, when an incoming call occurs, the incoming call notification is sent to the telephone device 10 registered by the IP telephone server 30. Upon receiving the incoming call notification, the telephone device 10 notifies the incoming call notification to the mobile terminal 20 (control unit 201) using the push function. When the incoming call notification is received from the telephone device 10 or when the user performs a call origination operation (step S104 “YES”), the control unit 201 activates the application (step S105) and transmits an acceptance notification to the telephone device 10. (Step S106). It is determined whether the use is outgoing or incoming, and if it is outgoing (step S107 “use outgoing”), a registration request is sent to the IP telephone server 30 (step S108). The mobile terminal 20 is registered in the IP telephone server 30, and the mobile terminal 20 can make a call (step S109). If the incoming call notification is determined in step S107, it is determined whether or not the incoming call is rejected (step S110). ). If the incoming call is rejected (step S110 “YES”), the process returns to step S103. If the incoming call continues after registration in the IP telephone server 30 (step S112 “YES”), normal incoming call processing is performed and the incoming call is answered (S113). If the incoming call is not continued (step S111 “NO”), the process returns to step S102.

  According to FIGS. 6 and 7, when receiving the proxy registration request from the mobile terminal 20 (step S <b> 201 “YES”), the control unit 111 of the main device 11 determines whether the proxy registration request or the proxy registration request is canceled ( Step S202). When it is determined that the request is a proxy registration request (step S202 “registration request”), the proxy registration mode is set (step S203), and an IP address registration request is made to the IP telephone server 30 as a proxy (step S204). If it is determined in step 202 that the proxy registration request is canceled, registration is performed in the IP telephone server 30 in the same manner, but the mobile terminal 20 is not notified even when an incoming call occurs (step S205). When receiving the incoming notification (step S206 “YES”), the control unit 111 determines whether or not the proxy registration mode is set. If the proxy registration mode is set (step S207 “proxy registration mode”), the control unit 111 notifies the mobile terminal 20 of the incoming notification. Notification is made by the push function (step S208).

  The mobile terminal 20 that has received the incoming call notification activates the application from the dormant state, makes an incoming call registration update request to the IP telephone server 30 and responds to the incoming call, but the mobile terminal 20 receives the incoming call notification from the telephone device 10. If the user does not want to respond to the call, or if the line service does not function due to out-of-service or the like and the call cannot be received, the incoming call notification from the telephone device 10 is not returned, and the incoming call that occurs thereafter is not notified. be able to. Therefore, when there is no response from the mobile terminal 20 within the predetermined time (step S209 “NO”), the control unit 111 makes an incoming call response (step S210). If there is an incoming call response within a predetermined time (step S209 “YES”), incoming call switching is performed (step S211), and the mobile terminal 20 responds to the incoming call.

  Although not shown in the flowcharts of FIGS. 6 and 7, the control unit 111 of the main device 11 also notifies the mobile terminal 20 of the caller's telephone number when making an incoming call notification using the push function. Thus, the mobile terminal 20 may determine whether or not to automatically answer the incoming call. By controlling in this way, it is possible to distribute incoming calls to terminals desired by the user without cooperation.

(Effect of embodiment)
For example, as shown in FIG. 1, the IP telephone system 1 according to the present embodiment includes a first telephone apparatus (mobile terminal 20) and a second telephone apparatus (telephone apparatus 10) by regular registration with the IP telephone server 30. ) Is an IP telephone system 1 that can use the IP telephone service with the same telephone number. In this IP telephone system 1, for example, as shown in FIG. 2, when the mobile terminal 20 transmits a proxy registration request to the telephone device 10 (step S11), the telephone device 10 that has received the proxy registration request Registration is performed on the server 30 in place of the mobile terminal 20 (step S13). Thereafter, when there is an incoming call addressed to the same telephone number, the registered IP telephone server 30 notifies the telephone device 10 of the incoming call (step S16), and the telephone device 10 that has received this incoming call notification receives the incoming call notification. Is transmitted to the mobile terminal 20 (step S17), and the mobile terminal 20 responds to the incoming call.

  In the existing IP telephone system, when double registration with different IP addresses is performed, incoming notification is sent to a terminal having an IP address registered later, so one telephone number is used at two or more locations. I couldn't. On the other hand, according to the IP telephone system 1 according to the present embodiment, the mobile terminal 20 located at another site transmits a proxy registration request to the telephone device 10 and the telephone device 10 performs registration on behalf of the telephone device 10. The mobile terminal 20 can use the IP telephone service with the same telephone number at another base, and at this time, it is possible to realize that the user answers the incoming call at the desired terminal without performing complicated settings. it can. In addition, since the destination of the IP telephone service can be switched only when necessary, convenience can be provided to the user.

  Conventionally, there is a method that allows one phone number to be used by another terminal by using the transfer function. However, the transfer function using another line requires a separate line and the caller's telephone number. There was a problem that became unknown. On the other hand, in the IP telephone system 1 according to the present embodiment, the telephone device 10 can also notify the caller's telephone number when making an incoming call notification to the mobile terminal 20 using the push function. It is also possible for the mobile terminal 20 to determine whether to automatically answer the incoming call. Conventionally, there is a method in which a mobile terminal is accommodated as a slave unit 12 of the main apparatus 11 and used at another site. However, when used at another site, there are problems in terms of security and voice quality. On the other hand, in the IP telephone system 1 according to this embodiment, the destination of the IP telephone service can be switched only when necessary while using the push function of the mobile terminal 20, and the telephone device 10 and the mobile terminal 20 Since these are controlled completely without being linked, the problems of security and sound quality degradation are avoided.

  Further, the mobile terminal 20 has a push function that activates a process (application) corresponding to the event when the event is received. When the telephone device 10 receives an incoming call notification from the IP telephone server 30, the mobile terminal 20 By notifying the incoming call notification to the terminal 20 by this push function, the mobile terminal does not always have to start the application, and can pause (sleep) during that time, and thus the power consumption of the mobile terminal 20 can be reduced.

  Further, according to the telephone device 10 according to the present embodiment, when a registration request request is received from another telephone device (mobile terminal 20), registration is performed with respect to the IP telephone server 30 on behalf of the mobile terminal 20. When an incoming call is received for the same telephone number and an incoming call notification is received from the IP telephone server 30, the incoming call notification is transmitted to the mobile terminal 20. Therefore, when using the IP telephone service with the same telephone number between the mobile terminal 20 and the telephone device 10 (for example, the fixed telephone terminal 12), the terminal on the side desired by the user without performing complicated settings It becomes possible to answer incoming calls. This function is effective when, for example, the user knows that there is a telephone call from a certain destination and receives the incoming call at the destination (mobile terminal side).

  Also, according to the telephone device (mobile terminal 20) according to the present embodiment, a proxy registration request is transmitted to another telephone device (main device 11), and the main device 11 replaces itself with the IP telephone server 30. After receiving registration, the incoming call response is made after receiving the incoming call notification sent from the main apparatus 11 that has received the incoming call notification from the IP telephone server 30 and has received the incoming call. Therefore, when using the IP telephone service with the same telephone number between the mobile terminal 20 and the fixed telephone terminal 12, it is possible for the user to answer the incoming call without making complicated settings. become. This function is effective when, for example, the user knows that there is a telephone call from a certain destination and receives the incoming call at the destination (mobile terminal side). For this reason, a user-friendly telephone device (mobile terminal 20) can be provided. Further, the mobile terminal 20 has a push function that activates a process (application) corresponding to the event when the event is received. When the telephone device 10 receives an incoming call notification from the IP telephone server 30, the mobile terminal 20 By notifying the incoming call notification to the mobile terminal 20 by this push function, the mobile terminal 20 can be suspended (sleep) during that time, and thus power saving of the mobile terminal 20 can be achieved.

  In addition, according to the telephone apparatus 10 which concerns on this embodiment, it consists of the main apparatus 11 which shares and controls a some external line and an extension, and the some fixed telephone terminal (slave machine 12) accommodated in the main apparatus 11. Although a business phone has been illustrated, a gateway or an exchange may be used instead. The mobile terminal 20 may be of any type as long as it has an Internet connection environment such as a smart phone or a tablet terminal in addition to the mobile phone terminal.

  Further, the program according to the present embodiment is executed by a computer (control unit 111) as shown in FIG. 3, for example, and is the same as other telephone devices (mobile terminal 20) by periodic registration with the IP telephone server 30. This is a program of the telephone device 10 that can use the telephone service with a telephone number, and is stored in a predetermined area of the storage unit 112. Then, for example, as shown in FIG. 6 and FIG. 7, when the computer receives a registration request request from the other telephone device, the program sends the request to the IP telephone server on behalf of the other telephone device. Processing for transmitting a registration request (steps S201 and S202), and processing for transmitting the incoming call notification to the other telephone device when an incoming call is received from the IP telephone server when there is an incoming call to the telephone number ( Steps S203 and S204) are executed.

  For this reason, according to the program according to the present embodiment, when using the IP telephone service with the same telephone number between the mobile terminal 20 and the fixed telephone terminal 12, the user can make a setting without performing complicated settings. It is possible to answer the incoming call at the terminal that performs the call. This function is effective when, for example, the user knows that there is a telephone call from a certain destination and receives the incoming call at the destination (mobile terminal side).

  The program according to the present embodiment is executed by a computer (control unit 201), for example, as shown in FIG. 4, and is the same as other telephone devices (telephone device 10) by periodic registration with the IP telephone server 30. A program of a telephone device (mobile terminal 20) that can use a telephone service with a telephone number, and is stored in a predetermined area of the storage unit 202. As shown in FIG. 5, for example, the program includes a process of transmitting a proxy registration request to the other telephone device to the computer (steps S101 and S102), and the other telephone device replaces itself. After receiving registration to the IP telephone server, if there is an incoming call addressed to the telephone number, it waits for reception of an incoming call notification sent from the other telephone device that has received the incoming call notification from the IP telephone server.
