In such a conventional terminal linkage function, when an incoming call is received to an individual telephone number, the incoming call can be notified only to either the extension telephone terminal or the wireless telephone terminal from the telephone control device. You can switch destinations.
However, there is a considerable operational burden on the user, such as a switching operation of the incoming call destination when leaving or returning, and there are cases where the incoming call cannot be answered due to forgetting to perform the switching operation.

For this reason, it is realistic that the telephone control device notifies the extension telephone terminal and the radio telephone terminal of the incoming call, and the user selects either one according to the incoming call situation and responds to the incoming call. .
Thus, for example, when a user is present, the user responds with an extension telephone terminal having a variety of functions and is easy to use, and when the user is away from the user, It becomes possible to respond at the telephone terminal.

Therefore, when realizing such a terminal linkage function, the telephone control device notifies the incoming call from the telephone control device to both the extension telephone terminal and the wireless telephone terminal that are linked when the incoming call is received to the individual telephone number. It is detected that the person has responded to the incoming call at either the extension telephone terminal or the wireless telephone terminal, and a call with the other telephone terminal is formed.
In addition, since a call to the other telephone terminal becomes unnecessary after answering the incoming call at one telephone terminal, the telephone control device notifies the incoming call to the other telephone terminal in response to the incoming call response at one telephone terminal. Will stop.

At this time, if the user responds to the incoming call with the wireless telephone terminal when the user leaves the seat, the ringing at the extension telephone terminal installed in his / her seat will stop, but the response at the wireless telephone terminal may be delayed. is there.
For this reason, if the response at the wireless telephone terminal is delayed, for example, when another user near the user's seat responds at the extension telephone terminal at the user's seat prior to the response at the wireless telephone terminal, the telephone control There was a problem that the incoming call from the apparatus to the radio telephone terminal was stopped. Therefore, in such a case, there is a problem that even if the user operates the wireless telephone terminal after answering at the extension telephone terminal, it is impossible to make a call with the other party.

  The present invention is for solving such a problem, and even when an incoming call response is first made at an extension telephone terminal that is linked to the wireless telephone terminal, the other party of the incoming call depends on the operation at the wireless telephone terminal. The object is to provide a telephone control technology capable of making a phone call.

  Also, in one configuration example of the telephone control device according to the present invention, when the call control unit responds to the incoming call after the initial response by the extension telephone terminal, the extension telephone terminal A conference call is formed by connecting the radio telephone terminal to a call with the other party telephone terminal.

  Also, one configuration example of the telephone control device according to the present invention is such that the call control unit mutes the voice from the radio telephone terminal to the other party telephone terminal at the start of the conference call.

  Also, in one configuration example of the telephone control device according to the present invention, when the cooperation control unit responds to the incoming call after the response at the extension telephone terminal, the wireless telephone terminal Is instructed to the extension telephone terminal.

  Also, in one configuration example of the telephone control device according to the present invention, when the call control unit responds to the incoming call, the extension telephone terminal makes a call with the partner telephone terminal when the wireless telephone terminal responds to the incoming call. If the call is on hold, the hold is released in response to the response by the wireless telephone terminal or the subsequent release of the hold by the wireless telephone terminal, and the wireless telephone terminal and the other telephone terminal are connected by a call. It is what you do.

  Further, the program according to the present invention is a program for causing a computer to function as each unit constituting any one of the above-described telephone control devices.

According to the present invention, even when an incoming call response is previously made at an extension telephone terminal that is linked to the wireless telephone terminal, the incoming call to the wireless telephone terminal is continued, and the other party of the incoming call depends on the operation at the wireless telephone terminal. You can talk to the other party.
Therefore, even if the response at the wireless telephone terminal is delayed, for example, when another user near the user's seat responds at the extension telephone terminal at the user's seat prior to the response at the wireless telephone terminal, The user who should respond can make a call from the wireless telephone terminal to the other user of the other telephone terminal.

  Therefore, it is possible to smoothly and properly use extension telephone terminals and wireless telephone terminals with the same individual telephone number without switching the destination when leaving or returning. Even when the response at the radio telephone terminal is sometimes delayed, it is possible to reliably talk with the other user, and it is possible to realize a terminal cooperation function that is extremely easy to use in the telephone control device.
