[0016]
Next, the operation of the above-described telephone system when receiving a call will be described. Here, a case where the public switched telephone network 2 is an ISDN line will be described as an example. FIG. 3 is a sequence diagram showing the operation of the telephone system when receiving a call. First, when an incoming call is made to the key telephone set 11, the exchange (not shown) of the ISDN line 2 transmits a SETUP (call setting) message to the main device 10 accommodating the called side key telephone set (step S101 in FIG. 3). .
[0017]
The control unit 105 of the main unit 10 that has received the SETUP message via the public switched telephone network I / F unit 100 transmits an ALERT (call) message to the ISDN line 2 via the public switched telephone network I / F unit 100. It is sent (step S102). Further, control unit 105 identifies key telephone 11 corresponding to the called number in the received SETUP message based on the extension number management table stored in storage unit 104. The extension number management table associates extension numbers with IDs of the key telephones 11.
[0018]
Here, assuming that the main device that accommodates the called key telephone 11 is 10A and the extension number corresponding to the called number is “13”, the control unit 105 of the main device 10A The telephone ID corresponding to the extension number “13” is acquired with reference to the extension number management table 110A. By acquiring the telephone ID, the key telephone corresponding to the called number is identified as 11A-3. Then, the control unit 105 of the main device 10A controls the key telephone 11A-3 through the extension I / F unit 102, makes the key telephone 11A-3 ring (step S104), and indicates that it is receiving a call.

[0022]
The exchange of the ISDN line 2 that has received the DISC message returns a REL (release) message to the main device 10A (step S122). The control unit 105 of the main device 10A that has received the REL message controls the switch 103 to disconnect the voice communication path between the partner telephone 4 and the key telephone 11A-3 (step S124), and RELCOMP (release completed) ) A message is transmitted to the ISDN line 2 (step S125). Further, control unit 105 turns off the lamp of key telephone 11A-3 to indicate that the call has ended (step S127), and returns the LCD of key telephone 11A-3 to the standby state (step S128).
[0023]
Next, the operation of the telephone system when making a dial call will be described. FIG. 5 is a sequence diagram showing the operation of the telephone system at the time of dialing. When a dial call occurs from the subordinate key telephone set 11 (step S201 in FIG. 5), the control unit 105 of the main device 10 specifies the extension number corresponding to the dial telephone set 11 based on the extension number management table. .
[0024]
Here, assuming that the dialed key telephone is 11A-3, the control unit 105 of the main device 10A refers to the extension number management table 110A as shown in FIG. 4 and refers to the extension number corresponding to the key telephone 11A-3. “13” is acquired. Then, control unit 105 of main device 10A creates a SETUP message including the outside line number (calling number) corresponding to extension number “13” and the called number received from key telephone 11, and transmits this SETUP message to the public telephone. The packet is transmitted to the ISDN line 2 via the switching network I / F unit 100 (step S204).

[0025]
The exchange (not shown) of the ISDN line 2 that has received the SETUP message returns a CALLPROC (call setting acceptance) message to the main device 10A (step S207). Furthermore, when the telephone 4 of the other party receives the incoming call, the exchange of the ISDN line 2 returns an ALERT (call) message to the main device 10A (step S208). The control unit 105 of the main device 10A that has received the ALERT message controls the switch 103 to connect the extension I / F unit 102 and the public switched telephone network I / F unit 100, thereby making the ISDN line 2 A voice communication path is formed between the other party's telephone 4 and the dial telephone 11A-3 (step S210). A ring back tone (RBT) is sent from the exchange on the ISDN line 2 to the main unit 10A, and the control unit 105 of the main unit 10 sends the RBT to the key telephone 11A-3.
[0026]
Next, when the other party's telephone 4 answers, the exchange of the ISDN line 2 transmits a CONN message to the main device 10A (step S211). Control unit 105 of main device 10A that has received the CONN message causes LCD of key telephone 11A-3 to display "Talking" (step S213). Thus, a voice call is started between the other party's telephone 4 and the key telephone 11A-3.
[0027]
Steps S214, S216, S217, S219, S220, S222, and S223 are the same as steps S119, S121, S122, S124, S125, S127, and S128, respectively.
[0028]
Next, a case will be described in which key telephone 11B-1 accommodated in main device 10B operates as key telephone 11A-3 accommodated in main device 10A. In this case, the extension number management tables 110A and 110B stored in the storage units 104 of the main devices 10A and 10B are rewritten to transmit and receive control data and voice data between the main devices 10A and 10B via the IP network 3. By doing so, the key telephone 11B-1 is apparently operated as a child device of the main device 10A.
[0029]
FIGS. 6A and 6B show extension number management tables 110A and 110B after rewriting. As shown in FIG. 4, in the extension number management table 110A of the main device 10A before rewriting, the key telephone 11A-3 is set as the assignment destination of the extension number "13". When operating the key telephone 11B-1 as the key telephone 11A-3, it is necessary to change the assignment destination of the extension "13" to the key telephone 11B-1. The extension number management table 110A is rewritten so that the IP address of the main device 10B accommodating the telephone set 11B-1 corresponds to the extension number "13" (FIG. 6A). This rewriting is performed from the information processing terminal 13A or the key telephone 11A connected to the main device 10A.
[0030]
On the other hand, in the extension number management table 110B of the main device 10B before rewriting, it is assumed that, for example, the extension number “10” is assigned to the key telephone 11B-1. When the key telephone 11B-1 is operated as the key telephone 11A-3, it is necessary to change the connection destination of the key telephone 11B-1 to the main device 10A, so that the IP address of the main device 10A is changed to the key telephone 11B-1. The extension number management table 110B is rewritten so as to correspond to the ID (FIG. 6B). This rewriting is performed from the information processing terminal 13B or the key telephone 11B connected to the main device 10B.
[0031]
The control unit 105 of the main device 10A needs to send control data to the key telephone 11A-3 (steps S104 to S106, S112 to S114, S118, S127, S128 in FIG. 3, steps S205, S206, and S205 in FIG. 5).
