A subscriber terminal 1 is connected to the public network 2. The public network 2 includes a central office switch. A private branch exchange (PBX) 4 is connected to the public network 2 via a line 3. 5 is PBX4
Is a plurality of extension terminals connected to. The extension numbers of these extension terminals are A, B, and C, respectively.

In the system thus constructed,
The extension terminals 5 can talk with each other. For example, when the extension terminal A calls the extension terminal C, the telephone number C of the other party may be dialed. Upon receiving the partner extension number, the PBX 4 connects the extension terminal A and the extension terminal C. This gives A and C
A path is set up between A and C so that A and C can talk.

On the other hand, each of these extension terminals 5 is given a number (for example, XX-YYYY) for making a telephone call from the outside, and the number given to these extensions is dialed from the external subscriber terminal 1. . For example, 22-5
When dialing 632, this calling number enters the PBX 4 via the public network 2 and the line 3. A conversion table of assigned numbers and extension numbers is provided in the PBX 4, and if 225-2632 corresponds to the extension number B, the path from the outside and B are connected. As a result, a path is established between the subscriber terminal 1 and the extension terminal B, and the call becomes possible (dial-in service).

The above-mentioned general services include call waiting, three-way calling, call transfer, and the like. What is call waiting
When another call comes in during a call, it is a function that allows you to talk to that phone as well. Normally, the call waiting function is realized by pressing the hook button. What is a three-way call?
It is a function to call a third party during a two-way call and make a three-way call. The call transfer is a function of transferring a telephone call to a subscriber terminal from the outside to a subscriber terminal having a different number by registering in advance in FIG.

[0006]

The conventional dial-in service described above and other general services cannot be provided to the same subscriber. Therefore, it is necessary for the subscriber side to fix and use the private branch exchange for dial-in service or general service.

The present invention has been made in view of the above problems, and an object thereof is to provide a dial-in / general service switching system capable of switching a dial-in function and a general service function. .
