Abstract

PURPOSE:To send a necessary message to a calling subscriber for each idle number information by sending again an idle number to a voice storing device with dial signals and then connecting this number to a corresponding device when the idle number information is received from the calling subscriber. CONSTITUTION:A called subscriber number sent from a calling subscriber SUB1 is received by an outgoing register ORT4, and the information on this subscriber number is transferred to a central controller CC15 via a register controller REGC13. The controller CC15 starts its number group to discriminate the called subscriber number is not busy. Thus the CC15 restores the connection SUB1- LC2-1'-ORT4 via an SWC12 and selects a talkie trunk TKT6 and a PBSd5. A connection link SUB1-LC2-3'-TKT6 is reserved, and the connection PBS5-2'- TKT6 is secured by an SWC12. Then the CC15 transmits the called subscriber number information received previously via an SNDC11 to the TKT6 for the PBS5. Then the CC15 restores the PBS5 when the PBS5 completes transmission of the called subscriber number information and then performs the connection SUB1-LC2-3'-TKT6 via the SWC12.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a voice message connection system in a telephone exchange.

(Prior art) Conventionally, empty number processing in telephone exchanges includes (1)
There was a busy tone transmission, (2) connection to a relay stand, and (3) connection to a talkie device (fixed message pattern).

These systems have the following drawbacks when implementing window number guidance by number change for subscribers. In other words, (1) the busy tone transmission method is impossible to implement, (2) the connection method to the relay stand imposes a heavy burden on the operator, and (3)
In the connection method to a talkie device, a talkie device is required to accommodate changing subscribers.

(Object of the Invention) The object of the present invention is to solve the above-mentioned drawbacks, and to send each necessary message to a calling subscriber from a common voice storage device for each vacant number information from the subscriber, such as number "2001". To provide a voice message connection method that can automatically notify that the extension number has been changed to "2111" and that "2100" is an empty number.

(Structure of the Invention) According to the present invention, there is provided a voice storage device having a function of receiving a dial signal and storing and transmitting a voice message based on the number information, and the device is connected via a trunk. In a telephone exchange configured to connect to an exchange, if the central controller identifies that the called extension number sent from the calling subscriber is a window number, the central controller will A voice message connection method characterized in that the window number information is controlled to be retransmitted from the sender device via the trunk, and a voice message corresponding to the window number stored in advance is transmitted to the caller. is obtained.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, in which pushbutton dialing (FB) signals are used, 1 is a calling subscriber (SUB), 2 is a line circuit (LC), and 3 is a block diagram of an embodiment of the present invention. Main switch (SW), 4 is outgoing register (ORT), 5 is P

C), 14 indicates a trunk control unit (TKO), and 15 indicates a central control unit (CO).

The called party number from 5UBI is received at OR, T4 in a known manner and the information is forwarded to CCl3 via REGC13. When CCl3 activates the number group of CCl3 and identifies that the called party number is a window number,
5WC12 restores the connection of 5UBI-LC2-■-0RT4, selects 'rKT6 and PBS5, reserves the link for connection of 5UBI-LC2-■-TKT6, and restores the connection of PBS5-■-TKT6 with 5WC12.
This is done by Furthermore, CCl3 is 5N to PBS5
The called party number information previously received via the DCII is sent to the TKT6.

On the other hand, when TKT6 is connected to PBS5 via 8WC12 by CCl3, at the same time, TKT6 receives an order to send a start signal to VSE7 via 1'KCl4 by CC,15, and starts VSE7. The incoming PB signal of the called party number is sent to the VP via TKT 6.
The information is received by U8, and VPU8 expands the information and searches for pre-stored audio files for each number information.

Next, when the PBS5 completes sending the called party number, the CCl3 restores the PBS5 and uses the previously reserved 5UB1.
-LC2-■-TK'l''6 is connected via 9WC12.

Through the above operations, the calling subscriber can hear a voice message from the voice storage device informing him or her which number the called party number has been changed to, or that it is a window number, for each pre-stored number information. Become.

It goes without saying that in the present invention, if a plurality of TKTs 6 are installed, it is possible to send voice messages to a plurality of calling subscribers at the same time.

(Effects of the Invention) As explained above, the present invention, when receiving window number information from a calling subscriber, resends the number to the voice storage device using a dial signal and connects to the device. It is possible to send each necessary message to the calling subscriber for each window number information, and the contents of number changes can be economically carried out using a common voice storage device for each vacant number.
