  Next, the operation of the IP telephone adapter 1 in FIG. 1 will be described in detail with reference to the flowcharts shown in FIGS. 4 and 5 and the connection form shown in FIG. 2 with reference to the sequence diagram in FIG.

  An IP telephone server 51 that is in the IP telephone network 50 and controls outgoing / incoming calls has a correspondence table of telephone numbers and IP addresses of the IP telephone adapter 1 and the IP telephone 52. When a call is made from the IP telephone 52 to the PBX terminal 41, the calling IP telephone 52 transmits an INVITE signal including the caller's IP address and the destination telephone number to the IP telephone server 51.

  The IP telephone server 51 receives the INVITE signal from the IP telephone 52, and extracts the IP address of the caller and the telephone number of the called party included in the INVITE signal. Then, the IP telephone server 51 converts the caller IP address into the caller telephone number and the callee telephone number into the callee IP address. The IP telephone server 51 transmits an INVITE signal including the converted caller telephone number and destination IP address to the destination IP telephone adapter 1 in order to notify the IP telephone adapter 1 of the incoming call from the IP telephone 52.

  The WAN interface circuit 11 in the IP telephone adapter 1 constantly monitors a control packet signal received from the IP telephone network 50. When the INVITE signal is received from the IP telephone server 51 (S01), the microcomputer 10 extracts the caller telephone number in the INVITE signal and stores it in the memory 12 (S02). Further, the microcomputer 10 reads the incoming time from the clock circuit 13 and stores it in the memory 12 (S03). Then, the microcomputer 10 controls the PBX interface circuit 21 and transmits an incoming signal to the PBX 40 (S04). Further, the microcomputer 10 transmits its state to the IP telephone server 51 as a status 180 (Ringing) (S05).

  After the incoming signal is sent to the PBX terminal 41, the microcomputer 10 periodically monitors the OFF HOOK detection circuit of the PBX interface circuit 21 (S06). While the PBX terminal 41 is not OFF HOOK, the microcomputer 10 determines whether the continuation of the incoming signal is equal to or greater than the timer value (S07). If the timer value is greater than or equal to the timer value, the microcomputer 10 transmits a BYE signal to the IP telephone server for communication. Disconnect (S11).

  Now, when the IP telephone 52 transmits to the PBX 40 side and the PBX terminal 41 makes an incoming call response, the microcomputer 10 periodically monitors the OFF HOOK detection circuit of the PBX interface circuit 21, so the PBX terminal 41 is OFF HOOK. Detect that Thereafter, the microcomputer 10 controls the WAN interface circuit 11 to notify that the PBX terminal 41 is OFF HOOK, and transmits a status 200 (OK) signal to the IP telephone server 51 (S08).

  The IP telephone server 51 that has received the status 200 (OK) signal transmits a status 200 (OK) signal to the IP telephone 52. IP telephone 52 transmits an ACK signal to IP telephone server 51 to notify the completion of reception of the 200 (OK) signal. The IP telephone server 51 that has received the ACK signal transmits an ACK signal to the IP telephone adapter 1 in order to notify the completion of reception of the 200 (OK) signal by the IP telephone 52.

  The microcomputer 10 of the IP telephone adapter 1 monitors reception of an ACK signal returned from the IP telephone server 51 (S09). Then, the microcomputer 10 determines whether or not the reception waiting time of the ACK signal is equal to or greater than the timer value (S10), and if it is equal to or greater than the timer value, transmits a BYE signal to the IP telephone server and disconnects communication ( S11).

  When the IP telephone adapter 1 receives the ACK signal, the WAN interface circuit 11 of the IP telephone adapter 1 notifies the microcomputer 10 that the ACK signal has been received from the IP telephone server 51. Then, the microcomputer 10 transmits the voice data received from the WAN interface circuit 11 to the PBX interface circuit 21 and establishes the voice data received from the PBX interface circuit 21 in order to establish a call path between the IP telephone 52 and the PBX terminal 41. The data is transmitted to the WAN interface circuit 11 (S12).

  When the call path is established, the caller of IP telephone 52 starts a conversation with the responder of PBX terminal 41. During the conversation, the microcomputer 10 of the IP telephone adapter 1 monitors ON HOOK of the PBX terminal 41 (S20). If ON HOOK on the PBX terminal 41 side is detected first, a BYE signal is transmitted to the IP telephone server 51 to disconnect the call path (S30).

  On the other hand, the microcomputer 10 of the IP telephone adapter 1 monitors the BYE signal transmitted from the IP telephone server 51 (S21). When ON HOOK on the PBX terminal 41 side is not detected and a BYE signal is received first from the IP telephone server 51, a BUSY signal is transmitted to the PBX terminal 41 (S22), and processing for creating a message mail Migrate to

  The microcomputer 10 of the IP phone adapter 1 monitors ON HOOK of the PBX terminal 41 (S23). If the PBX terminal 41 detects ON HOOK without sending a DTMF signal from the PBX terminal 41, the IP phone adapter 1 does not perform the message mail creation process and sends it to the IP phone server 200. An (OK) signal is transmitted, and the call path is disconnected (S29). In addition, when the reception waiting time of the DTMF signal sent from the PBX terminal 41 becomes equal to or greater than the timer value (S25), the IP telephone adapter 1 does not perform the message mail creation process and sends 200 ( An OK signal is transmitted and the call path is disconnected (S29).

  When the caller of the IP telephone 52 finds out by conversation with the responder of the PBX terminal 41 that the other party who wants to talk cannot go out, such as going out or in a meeting, he asks him to call back and makes an ON HOOK first. At this time, the IP telephone 52 transmits a BYE signal to the IP telephone server 51. The IP telephone server 51 that has received the BYE signal transmits the BYE signal to the IP telephone adapter 1 in order to notify ON HOOK of the IP telephone 52.

  The IP telephone adapter 1 monitors the reception of the BYE signal transmitted from the IP telephone server 51 (S21). When receiving the BYE signal from the IP telephone server 51, the WAN interface circuit 11 notifies the microcomputer 10 of this. The microcomputer 10 controls the PBX interface circuit 21 to transmit a BUSY tone to the PBX terminal 41 (S22).

  The proxy responder of the PBX terminal 41 who has heard the BUSY tone operates the numeric keypad on the PBX terminal 41 and inputs the extension telephone number of the absent person. The PBX terminal 41 transmits the DTMF signal input from the numeric keypad to the PBX interface circuit 21.

  The IP telephone adapter 1 monitors the DTMF signal transmitted from the PBX terminal 41 (S24). When the DTMF signal is received, the DTMF detection circuit 25 of the PBX interface circuit 21 receives and analyzes the DTMF signal and notifies the microcomputer 10 as DTMF reception data. The microcomputer 10 stores the DTMF reception data notified from the DTMF detection circuit 25 in the memory 12 as the extension telephone number of the absent person.

  When the proxy responder of the PBX terminal 41 turns ON HOOK to end the call, the OFF HOOK detection circuit of the PBX interface circuit 21 notifies the microcomputer 10 that the PBX terminal 41 is turned ON HOOK. The microcomputer 10 that has recognized ON HOOK transmits a 200 (OK) signal to the IP telephone server 51 by controlling the WAN interface circuit 11 in order to notify that the PBX terminal 41 is ON HOOK.

As shown in Table 1, a correspondence table of extension telephone numbers and e-mail addresses is registered in the memory 12 in advance. The microcomputer 10 refers to the memory 12 and obtains the e-mail address of the absent person corresponding to the received extension telephone number (S26).

  The microcomputer 10 reads the incoming time and caller telephone number stored at the time of incoming call from the memory 12, and creates an e-mail as shown in FIG. 6 with the incoming time and the caller telephone number added to the e-mail address of the absent person ( In step S27, the WAN interface circuit 11 is controlled to transmit an electronic mail to the Internet network (S28).

  The absentee can know when and who received the call by receiving an e-mail on the personal computer 61 or the personal computer 62 connected to the Internet.

  Next, another embodiment of the present invention will be described. In the present embodiment, the basic configuration is as shown in FIGS. 1 and 2 above, but the e-mail creation method is further devised. The flowchart is shown in FIGS. In this example, by using a special number, an arbitrary message mail is selected from a plurality of types of message mails prepared in advance and transmitted.

  First, it is assumed that the IP telephone 52 transmits to the PBX terminal 41 and the proxy responder receives the call. At this time, as shown in the flowchart of FIG. 4, a call path between the IP telephone 52 and the PBX terminal 41 is established (S12). The caller of IP telephone 52 starts a conversation with the responder of PBX terminal 41.

  As shown in FIG. 7, the microcomputer 10 of the IP telephone adapter 1 monitors the ON HOOK of the PBX terminal 41 (S40), and when the ON HOOK on the PBX terminal 41 side is detected first, the IP telephone server 51 A BYE signal is transmitted to the telephone and the call path is disconnected (S52).

  On the other hand, the microcomputer 10 of the IP telephone adapter 1 monitors the BYE signal transmitted from the IP telephone server 51 (S41). When ON HOOK on the PBX terminal 41 side is not detected and a BYE signal is received first from the IP telephone server 51, a BUSY signal is transmitted to the PBX terminal 41 (S42), and processing for creating a message mail Migrate to

  The microcomputer 10 of the IP telephone adapter 1 monitors ON HOOK of the PBX terminal 41 (S43). If the PBX terminal 41 detects ON HOOK without sending a DTMF signal from the PBX terminal 41, the IP phone adapter 1 does not perform the message mail creation process and sends it to the IP phone server 200. An (OK) signal is transmitted and the call path is disconnected (S51). Also, when the reception waiting time of the DTMF signal transmitted from the PBX terminal 41 becomes equal to or greater than the timer value (S45), the IP telephone adapter 1 does not perform the message mail creation process and sends 200 ( An OK) signal is transmitted and the call path is disconnected (S51).

  Here, it is assumed that the caller of IP telephone 52 finds that the other party to call is absent and first turns on IP telephone 52. At this time, the IP telephone 52 transmits a BYE signal to the IP telephone server 51. The IP telephone server 51 that has received the BYE signal transmits the BYE signal to the IP telephone adapter 1 in order to notify ON HOOK of the IP telephone 52.

  The WAN interface circuit 11 of the IP telephone adapter 1 receives the BYE signal from the IP telephone server 51 (S41) and notifies the microcomputer 10 of it. The microcomputer 10 controls the PBX interface circuit 21 to transmit a BUSY tone to the PBX terminal 41 (S42).

  The proxy responder of the PBX terminal 41 who has heard the BUSY tone inputs the extension telephone number of the absent person using the numeric keypad in the PBX terminal 41 following the one-digit special number. The PBX terminal 41 transmits the DTMF signal input from the numeric keypad to the PBX interface circuit 21.

  The IP telephone adapter 1 monitors the DTMF signal transmitted from the PBX terminal 41 (S44). When the DTMF signal is received, the DTMF detection circuit 25 of the PBX interface circuit 21 receives and analyzes the DTMF signal transmitted from the PBX terminal 41 and notifies the microcomputer 10 of the DTMF reception data.

  The microcomputer 10 of the IP telephone adapter 1 stores in the memory 12 the first digit of the DTMF reception data notified from the DTMF detection circuit 25 as a special number and the second and subsequent digits of the DTMF reception data as the extension telephone number of the absent person. Keep it.

  When the proxy responder of the PBX terminal 41 turns ON HOOK to end the call, the OFF HOOK detection circuit of the PBX interface circuit 21 notifies the microcomputer 10 that the PBX terminal 41 is turned ON HOOK. The microcomputer 10 that has recognized ON HOOK transmits a 200 (OK) signal to the IP telephone server 51 by controlling the WAN interface circuit 11 in order to notify that ON HOOK has been performed.

  In the memory 12, a correspondence table of extension telephone numbers and e-mail addresses is registered in advance. The microcomputer 10 reads the memory 12 and converts the received extension telephone number into the corresponding absentee's e-mail address (S46).

  At the same time, the microcomputer 10 reads the special number from the memory 12 and, if the special number is “1”, creates a message mail corresponding to this “1”. The microcomputer 10 reads the incoming time and the caller telephone number stored at the time of the incoming call from the memory 12, and adds the incoming call time and the caller telephone number to the e-mail address of the absent person as shown in FIG. An electronic mail is generated, and the WAN interface circuit 11 is controlled to transmit the electronic mail to the Internet network.

  On the other hand, when the special number is other than “1”, the IP telephone adapter 1 creates a message mail corresponding to other than “1”. As shown in FIG. 8, the microcomputer 10 reads the incoming time and caller telephone number saved at the time of incoming call from the memory 12, and adds the incoming time to the e-mail address of the absent person and the caller's telephone number with “There was a call”. An electronic mail is generated, and the WAN interface circuit 11 is controlled to transmit the electronic mail to the Internet network.

  Thus, by using the “special number”, it is possible to send an accurate comment with an easy operation. That is, if the caller of the IP phone 52 wants to call back, enter the special number “1” and hope that the caller of the IP phone 52 wants to know that there was a call. If there is a special message other than “1”, an appropriate message mail can be created.

  Absents can receive e-mails on PCs 61 and 63 connected to the Internet network, PCs 62 and 63 connected to the HUB 32, and mobile phones, and so on. I know what to do.
