Abstract

PURPOSE:To relieve a very busy called subscriber to validate the called given to him/her and to increase the chances of conversations for the subscriber, by attaining the voice calls to a multi-function telephone at the side of the called subscriber through a general telephone or a multi-function telephone having no voice call key. CONSTITUTION:A central processing unit 209 judges the validity or invalidity of the hooking produced in a calling state based on the system data of a memory 210. Then the processor 209 catches an idle register circuit 200 when the validity of the hooking is decided. The circuit 200 is connected to a telephone 206 via a general telephone control circuit 205 in preparation for the reception of numeric characters. Then a special dial tone is sent to the telephone 206 and the telephone 206 dials an access code for voice calling. The circuit 200 receives the numeric characters corresponding to the relevant access code through a switch 201 and transmits the information to the processor 209 via an interface circuit 208. The processor 209 enables a voice call to a called subscriber who gives no answer through the telephone 206. Thus the called subscriber called out through a speaker device can give a hand-free answer.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a voice call system for a callee's multi-function telephone operator in an automatic telephone exchange. , between multifunction telephones equipped with a microphone and a speaker, from the called party's call-in-call response state to the calling party's 77 for voice calling mode.
The conventional method is to close the communication path and turn on the speaker device of the called party by pressing the button / button, and then to call the called party by voice through the speaker.

Therefore, there is a drawback that voice calls cannot be made from multi-function telephones or ordinary telephones that do not have a function button for voice calls.

Problems to be Solved by the Invention An object of the present invention is to provide a voice call system that solves the above-mentioned drawback, namely, that voice calls cannot be made from multi-function telephones and general telephones that do not have function buttons. It is in.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a multifunction telephone having at least a microphone and a speaker device;
The automatic telephone exchange comprises a power collection machine and an automatic telephone converter, and the automatic telephone exchange has a call path switch, a control circuit for multi-function telephones and general telephones connected to the switch, a register circuit, and a central processing unit. In an automatic telephone switching system consisting of - When calling another multi-function telephone from a power collection machine or a multi-function telephone, when the called multi-function telephone does not respond, the calling telephone is hooked from the ringing state. Then, by dialing the access code number for voice calling, a system is adopted in which the caller makes a voice call through the speaker device of the called party's multi-function telephone.

Operation Since the present invention is constructed as described above, when the multi-function telephone of the called party does not answer, the calling telephone performs hooking and then dials, thereby allowing the central processing unit of the automatic telephone exchange to access the register circuit. The code number is recognized, and when it is determined to be correct, the speaker device of the multi-function telephone on the called side is activated to notify the operator of the call.

In this way, the called party's multifunction telephone can be called by voice from the calling party's telephone.

Example Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1 showing an embodiment of the present invention, an automatic telephone exchange using the voice calling system of the present invention includes a central processing unit 209, a communication path switch 201, and a data memory 21.
0, an interface circuit 20g, a register circuit 200 connected to both the interface circuit 208 and the communication path switch 201, a multi-function telephone control circuit 202, and a power collection machine control circuit 205. has been done. Further, the multifunction telephone control circuit 202 can control the multifunction telephones 203 to 204, and the power collection machine control circuit 205 can control the general telephones 206 to 207.

FIG. 2 is an external view showing an example of the configuration of a multi-function telephone, which includes a handset 100, a hook switch 101, a display panel 102, a function button 103, a speaker 104, a dial button 105, and a microphone 106. It consists of

Next, the operation of the voice calling system of the present invention will be explained.

First, it is assumed that the power collection device 206 is calling the multifunction telephone 203. Subsequently, since the multi-function telephone 203 does not respond, the telephone 206 performs a 7-call operation to make a voice call to the multi-function telephone 203. General telephone control circuit 205 detects this and transmits the information to central processing unit 209 through interface circuit 208. The central processing unit 209 enables/disables hooking from the calling state.
Invalidity is determined based on the system data in the data memory 210. If invalid, the calling state is continued; if valid, the empty register circuit 200 is captured, and the general telephone control circuit 2
05 to the telephone 206 and prepares to receive numbers. However, the multifunction telephone 203 continues to make calls. When preparations for receiving digits are completed, a special dial tone is sent to telephone 206, and after confirming this, telephone 206 dials an access code for a voice call. Register circuit 200 receives the number corresponding to the access code through switch 201 and transmits the information to central processing unit 209 through interface circuit 208 . The central processing unit 209 determines what the received number is while referring to the data memory 210, and if it matches the access code for voice calling, disconnects the register circuit 200, stops calling the telephone 203, A command is sent to switch 201 and control circuits 202 and 205 so that a communication path between telephone 206 and telephone 203 is established. Further, the microphone/speaker device of the telephone 203 is turned on, allowing a voice call to be made from the telephone 206 to the other party who does not respond. The called party who is called through the speaker device can make a hands-free response to the calling party 206 through the microphone device without using a receiver. When the called party takes off-hook the receiver of the telephone set 203, a normal conversation state is entered.

Note that any off-hook of telephone 203 while receiving digits is regarded as a response to a call from telephone 206. Furthermore, even when the register circuit 200 is receiving numbers, the telephone 206
When the telephone 206 is on-hook, the telephone 206 can return to the single ringing state of the telephone 203 at any time.
06 are both returned to the empty state.

If the received number does not match the voice call access code, the central processing unit 209 sends the register circuit 2
00 is disconnected and a restriction tone is sent to the telephone 206. However, it is assumed that the telephone 203 continues to make calls. Even if the access code is for a voice call, if the called party is a regular telephone, a restrictive tone is similarly sent out to notify that the called party does not have a speaker.

Effects of the Invention As explained above, according to the present invention, it is possible to make a voice call to the called party's multi-function telephone even from a general telephone or a multi-function telephone without a voice call button. This has the effect of relieving a called party who cannot release the call so that all calls are valid, and increasing the chances of a call.
