DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange apparatus of the present invention, and more particularly, to a telephone exchange apparatus for preventing a wrong telephone call.

[0002]

2. Description of the Related Art A conventional telephone exchange of this type will be described with reference to the drawings.

FIG. 5 is a block diagram showing a conventional example.

FIG. 5 shows the contents of this prior art telephone exchange apparatus disclosed in Japanese Patent Application Laid-Open No. 62-100062. When A dials the telephone number of the called party B, the ORT 112 detects the number. , Via the TSCN 118 to the CC 119. The CC 119 reads out the called party name and the address information stored in the DR 121 from the called party number, transfers the information to the talker device 124, and also uses the SC 116 to call the calling telephone and the talker device 12.
4 is connected by a route b. Talkie device 124
Notifies A of the called party name and its address.

[0005] Caller A listens to the called party name and address, and if the dialed number is incorrect, goes on-hook to complete the call. If there is no mistake, dial a specific number that is specified in advance to
A subsequent connection is requested to 119. The connection request may be made after a certain period of time.

[0006] Thereby, the CC 119 establishes a route b connecting the telephone set 101 and the talkie apparatus 124 by the SC 116.
Is disconnected and the telephone 101 and R
BT114 and telephone 1 by route d
02 and the RGT 115, a ringing tone is sent out to A and a calling signal is sent out to B.

When the RGT 115 detects that B has gone off-hook and notifies the CC 119 via the TSCN 118, the CC 119 disconnects the route c and the route d by the SC 116 and connects the telephone 101 with the IOT by the route e.
113, and the telephone 102 and the IOT 113 via the route f. Thereafter, A and B enter a talking state.

[0008]

This conventional telephone exchange device comprises a storage device storing subscriber information and a talkie device for performing a talkie service based on the contents thereof, and corresponds to the dialed number at the time of calling. By notifying the calling party of the information of the called party, it is possible to avoid a wrong telephone call that was known only after the called party actually answered, However, there is a problem that a storage device having an enormous storage capacity for storing subscriber information is required. Also, unless a complaint is received from the subscriber, the telephone exchange equipment cannot recognize and deal with it, so even if the number of registered subscribers is limited, the criteria for selecting subscribers to be registered in advance are ambiguous. In addition, there is a problem that post-treatment is required.
