Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer system of an exchange, and in particular, identifies a call having a different terminal type and automatically selects a communicable terminal near a called party. It relates to a transfer method of a call to be connected.

2. Description of the Related Art Conventionally, in a transfer system of an exchange, a called party previously sets a transfer source, and after a transfer is set, a call arriving at a corresponding telephone (or terminal) is unconditionally set to a transfer source. Transfer, that is, only between terminals of the same type can be transferred.

Problems to be Solved by the Invention However, in the conventional transfer method of the exchange, since transfer is performed unconditionally irrespective of the terminal type of the calling side, communication may not be possible when terminal types are different. From the viewpoint of the calling side, there is a drawback that the terminal cannot communicate with the called side terminal unless the telephone number of each terminal is known in addition to the telephone number of the calling side.

That is, when the calling party wants to communicate with a terminal other than the other party's telephone (for example, a facsimile), there is a problem that communication is not possible unless the telephone number of the other party's telephone is known in addition to the telephone number of the other party's telephone.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and accordingly, an object of the present invention is to provide a new selective call transfer system for an exchange, which can solve the above-mentioned problems inherent in the conventional technology. Is to do.

Means for Solving the Problems In order to achieve the above object, a call transfer method according to the present invention includes a means for identifying a type of an accommodation device corresponding to a telephone number, and the same method as that of the telephone from the telephone number of the telephone. A means for searching for a telephone number of a terminal in a region, and when a call is received at a called telephone, if the calling terminal is not a telephone, communication can be performed among terminals arranged near the called telephone. Means for selecting and connecting a terminal.

Next, a preferred embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a diagram showing an example of a transfer management table.

Referring to FIG. 1 and FIG. 2, in the present embodiment, the facsimile terminals 100 and 101 of the subscriber numbers # 100 and # 101 and the telephone set 102 are connected to the exchange section 103 of the exchange. Among them, the facsimile terminal 101 is installed in the same area (nearby) as the telephone 102.

The switching unit 103 is connected to a register circuit 104 for identifying a called party number at the time of an incoming call, and a control unit 105 for controlling connection of a call. The control unit 105 includes a telephone number and a terminal type of the subscriber. , And a transfer management table for searching the telephone number of a terminal in the same area as the telephone from the telephone's subscriber number
Manages 106.

 An operation example according to the above configuration of the present invention is as follows.

First, the caller A receives the callee B from the facsimile terminal 100.
When the document is sent by facsimile to the called party B, since the telephone number # 101 of the facsimile terminal 101 of the called party B is not known, a call is made to the phone number # 200 of the called party B ().

The telephone number # 200 of the called party B is identified by the register circuit 104 and notified to the control unit 105 (). The control unit 105 searches the transfer management table 106 and finds out the subscriber number # 1 of the caller A.
00 and the terminal type of the subscriber number # 200 of the called party B are collated. As a result, a mismatch between the terminal type (facsimile) of the calling party and the terminal type (telephone) of the called party is detected, and the call is not connected to the terminal 102 of the telephone number # 200 (), but the transfer table is set. The terminal number # 101 in the same area as the telephone number # 200 registered in 106 is searched.

Next, the control unit 1045 collates the terminal type of the calling subscriber number # 100 with the terminal type of the above-mentioned terminal number # 101, and connects the line because they are the same type ().

Advantageous Effects of the Invention As described above, according to the present invention, by controlling the terminal type and installation area by the exchange, the caller's telephone can be called even if the caller does not know the telephone number of the called facsimile terminal. As long as the number is known, the exchange can automatically perform the communication by selecting and connecting to the called terminal corresponding to the calling terminal.
