〔Example〕

The present invention will be explained in detail with reference to Examples below.

FIG. 1 shows the configuration of a caller notification device of a private branch exchange in one embodiment of the present invention.

In this device, the ISDN line 11 is connected to individual extension terminals 151 and 15-2 via an ISDN rank 12, a main switch 13, and a line circuit group 14 that constitute a private branch exchange. A voice synthesis message sending circuit 17 is connected to the main switch 13 . The speech synthesis message sending circuit 17 is a circuit for synthesizing speech and sending it as a message such as a company name, a person's name, etc. ISD
N trunk 12, main switch 13 and line circuit group 1
4 is connected to the control device 20.

The control device 20 includes a call setting message detection section 21 connected to the ISDN rank 12, a connection control section 22 connected to the voice synthesis message sending circuit 17 and the main switch 13, and a terminal connected to the line circuit group 14. Control unit 23
and a response detection section 24. The call setting message detection unit 21 detects a call setting message when an incoming call is received on the ISDN line 11, and supplies the data to the calling number and calling subaddress information element reading unit 25 and the keypad, called number and called subaddress information element reading unit 26. It is supposed to be done. Calling number and calling subaddress information element reading section 2
5 sends the read caller number and caller address information element to the computer 31 located outside the control device fif 20 via the external computer interface section 27. The computer 31 is equipped with a storage unit that associates numbers with companies or people's names, and is configured to search for companies or people's names based on the calling number and calling subaddress information elements.

On the other hand, the keypad, called party number, and called party address information element reading section 26 identifies the extension terminal that received the call, and notifies the terminal control section 23 of the result.

A search result of a company or a person's name by the computer 31 is manually inputted to the control device 20 and then inputted via the external computer interface section 27 to the information reading section 28 from the external computer. The terminal control section 23 is configured to supply the search results of the company or person's name outputted by the information reading section 28 from the external computer to the connection control section 22 and the terminal control section 23 . The connection control unit 22 sends the search results of the company or person's name to the speech synthesis message sending circuit 17.
to create a speech synthesis message. This voice synthesized message is sent to the answering extension terminal 15 via the main switch 13, but is also sent to the voice message sending end detection section 29 at the same time. When the voice message transmission end detection section 29 detects the end of the transmission of the voice synthesized message, it notifies the connection control section 22 of this.

A series of operations of the caller notification device configured as above will be explained with reference to FIG.

When a call is received on the ISDN line 11, the call setting message detection unit 21 in the control device 20 detects a call setting message (step 2). The keypad, called number, and called subaddress information element reading section 26 reads the keypad, called number, and called subaddress information elements based on this (step 2). Then, from these data, the extension terminal that received the call is identified (step ■). In addition, the calling number and calling subaddress information element reading unit 25
The calling number and calling subaddress information elements are read (step ■).

If the calling number and calling sub-address information element reading unit 25 does not find the calling number or calling sub-address (step ■; Y), the process shifts to the regular routine process (next process). do.

Since this processing is not directly related to the present invention, its explanation will be omitted.

On the other hand, if the calling number or calling address exists, (N
), the calling number and calling address information element reading unit 25 sends the calling number and calling address information element to the computer 31 via the external computer interface unit 27 (step ①). The computer 31 stores in a storage unit (not shown) a comparison table of calling number and calling sub-address information elements, and company names or person names associated with these. When the calling party number and calling subaddress information element are received from the external computer interface section 27, a search operation is started to search for the corresponding company name or person's name (step 2). The information reading section 28 from the external computer reads this search data (step ■). If the search data does not exist (step ■; N), it is not possible to notify the company name or person's name. process). Since the present invention is not directly related to this, the explanation will be omitted.

On the other hand, when the computer 31 searches for search data (step 2: Y), the information reading section 28 from the external computer reads the search results (step 2). Then, from the terminal control unit 23, the corresponding extension terminal 1
5 is sent to the line circuit group 14 (step 0). For example, if the extension terminal 15-1 is the relevant terminal, the response detection unit 24
The response from 5-1 is being monitored. When a response to the ringing tone is detected (step 0), the voice synthesized message sending circuit 17 and the extension terminal 15-1 are connected (step 0). At this stage, the connection control unit 22 sends message information to be subjected to speech synthesis to the speech synthesis message sending circuit 17 (step 0). This results in
A voice synthesis message is sent from the voice synthesis message sending circuit 17, and the main switch 13 and line circuit group 14
The company name or person's name is notified to the corresponding extension terminal 15-1 via.

When the sending of the voice synthesized message is completed, the voice message sending end detection unit 29 detects this (step ■).
. Then, the connection control unit 22 is notified that the transmission of the voice synthesis message has been completed, and the voice synthesis message transmission circuit 1
