JPH0353744A - Electronic exchange with automatic caller number notice function - Google Patents

Abstract

PURPOSE:To allow a called party to confirm a telephone number of a caller based on a converted caller number by converting the caller number and storing the number, and sending the converted caller number to the called party and the caller when the called party replies the call. CONSTITUTION:A caller number converted by a central processing unit 3 is stored to a caller number storage area 5 when a caller 8 hooks off its handset. The caller number to be converted is generated by the central processing unit 3 based on a caller number before the conversion by using a reference table. When a called party 11 replies the call and a reply signal is received by a trunk 6 via an electronic exchange 10, the converted caller number stored in the caller number storage area 5 is read by the central processing unit 3 and sent to the caller 8 and the called party 11. Thus, the called party confirms the telephone number of the caller based on the converted caller number.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to electronic switching equipment, and more particularly to a calling party ID system.

[Conventional technology]

Conventionally, when a caller's number is not received from a special emergency or emergency phone call, or a call from a subscriber recognized as the most important, the caller number registered in advance by the called party You can search for the calling number using the search command.
This was possible only within the range of the local exchange. [Problems to be Solved by the Invention] The conventional electronic exchanges described above do not have a function to search for the calling party number when a call is made from another exchange, so it is difficult for the called party to know the calling party number. The disadvantage is that it cannot be done.

[Means to solve the problem]

The electronic exchange with the automatic caller ID notification function of the present invention has a calling number storage area, and a function that converts the calling number of the caller into another calling number when the calling party goes off-hook. , stored in the calling party number storage area, and when a called party's response signal is received by the trunk, reading the converted calling party number from the calling party number storage area and transmitting it to the called party. It also has a control means for transmitting information to the caller. [Effect 1: When the called party answers, the converted calling party number is sent to the called party and the calling party, so the called party can make a call based on this converted calling party number. You can check the phone number of the person,
Also, until the called party confirms the caller's phone number,
Since the called party does not know the calling party number before conversion, the calling party does not receive any inquiries from the called party, and therefore the calling party can call other emergency contacts one after another.

[Example] Next, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an electronic exchange with an automatic calling party number notification function according to the present invention.

The electronic exchange 1 of this embodiment includes a main storage device 4 having a calling number storage area 5, a central processing unit 3, and a trunk 6.
, a switching network 2 , and a subscriber circuit 7 , and accommodates a calling party 8 . The electronic exchange l connects the electronic exchange 10 accommodating the called party 11 via a trunk line 9.
connected to. The calling number storage area 5 contains the number of calling party 8.
When the caller goes off-hook, the converted calling party number is stored by the central processing unit 3. The calling party number converted in this way is created by the central processing unit 3 based on the calling party number before conversion, using a comparison table or the like.

Next, the operation of this embodiment will be explained. When the calling party 8 goes off-hook to make a call, the subscriber circuit 7 of the electronic exchange 1 accommodating the calling party 8 detects that the telephone of the calling party 8 is in use, and the central processing unit 3 As a result, the calling number of the calling party 8 is converted and stored in the calling number storage area 5. Next, when the calling party 8 dials the called party number, the called party 11 is contacted via the electronic exchange lO, which is connected to the electronic exchange 1 via the central line 9 and accommodates the called party l1. A calling signal is sent out.

When the called party l1 answers and a response signal is received by the trunk 6 via the electronic exchange lO, the converted calling party number stored in the calling party number storage area 5 is stored by the central processing unit 3. being read out and switching network 2
is received by the trunk 6 via the electronic exchange IO and transmitted to the called party 11 via the switching network 2 and the subscriber circuit 7 to the calling party 8, completing the transmission of the converted calling party number. After that, information indicating that the connection is complete is sent back to the calling party 8. When the calling party 8 is connected to the called party 11, ends the conversation with the called party 11, and goes on-hook,
It is possible to call other emergency contacts (not shown) one after another without receiving an inquiry from the called party 11. [Effect of the Invention] As explained above, the present invention converts and stores the calling party number, and when the called party answers, the converted calling party number is sent to the called party and the calling party. By transmitting this, the called party has the effect of being able to confirm the calling party's telephone number after the call from this specific calling party ends based on this converted calling party number.
