JPS5957552A - Incoming transfer device with communication recording function - Google Patents

Abstract

PURPOSE:To attain the incoming transfer with communication recording possible for recording the content of communication, by performing automatic dial from another telephone line and coupling mutually telephone lines in terms of AC when an incoming call comes to a telephone line so as to compensate bidirectional loss. CONSTITUTION:When a call signal comes to a telephone line, it is detected at a call signal detecting circuit 8, a line circuit 2 constitutes a channel, which is coupled to an amplifier circuit 3, a control signal of the circuit 8 starts an automatic dial circuit 9 to constitute a channel of the other telephone line and a preset telephone number is dialed automatically. When a called party responds, the response is detected at a called party response detecting circuit 7, a line circuit 4 constitute the channel, which is coupled to the circuit 3 so as to attain the bidirectional communication of both telephone lines, the bidirectional loss is compensated at the circuit 3 to attain normal communication state. Further, a communication recording circuit 10 is started with a control signal of the circuit 7 to record the content of mutual communication.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a call transfer device that can automatically transfer an incoming call to another phone, and more particularly to an incoming call transfer device with a call recording function.

Traditionally, typical call transfer devices of this type include:
Combining an answering machine and an automatic dialing device, recording the caller's message on the answering machine, automatically dialing a preset telephone number after the recording is completed, and transmitting the recorded contents after the other party answers. However, the message was one-sided from the caller, which was inconvenient in terms of the immediacy of the call and the preservation of the communication content.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, an object of the present invention is to configure a communication circuit quickly in response to a call signal from a telephone line,
The phone number of the called party is automatically dialed using another telephone line, and after the dialing is completed, the two telephone lines are connected in an alternating current manner, and after the called party answers, the two-way loss of the two telephone lines is eliminated. Compensating amplifiers enable intercommunication,
To provide a call transfer device with a call recording function capable of recording the content of mutual calls.

The call recording function attached call transfer device of the present invention includes a means for detecting a ringing signal of a first telephone line and closing the first telephone line, and a means for closing the second telephone line in response to the ringing signal. means for automatically dialing the called party on the first telephone line; means for detecting on-hook of the calling party on the first telephone line; and means for detecting a response from the called party on the second telephone line; means for AC-coupling the first and second telephone lines; amplification means for compensating for bidirectional losses in the first and second telephone lines; and means for recording the contents of the call.

Next, an embodiment of the present invention will be described with reference to the same subject.

FIG. 1 is a block diagram of an embodiment of the invention.

1 is a telephone line connection terminal for connecting a first telephone line; 2 is a line circuit forming a speech circuit of the first telephone line; 5 is a telephone line connection terminal for connecting a second telephone line; 4 is a second telephone line connection terminal;
8 is the first line circuit that constitutes the telephone communication circuit of the telephone line.
6 is an on-hook detection circuit that detects and controls when the caller of the telephone line of chain 1 goes on-hook when the first telephone line is in the telephone circuit configuration; 7 is an automatic dialing circuit that automatically dials a preset telephone number; 7 is a called party response detection circuit that detects and controls when the called party on the second telephone line has answered; 3 is the first and second telephone line; An amplifier circuit compensates for losses in both directions of the line, and 10 is a call recording circuit that records the contents of calls on the first and second telephone lines.

When a calling signal arrives at the first telephone line, it is detected by the calling signal detection circuit 8 via the telephone recollection connection terminal 1 and the line circuit 2, and the line circuit 2 constitutes a calling circuit and is coupled to the amplifier circuit 3, and the calling signal is sent to the first telephone line. The automatic dialing circuit 9 is activated by a control signal from the detection circuit 8, forms a communication circuit for the second telephone line, and automatically dials a preset telephone number. After the automatic dialing is completed, if the called party on the telephone line of the tube 2 answers, it is detected by the called party response detection circuit 7, and the line circuit 4 constitutes a communication circuit, which is connected to the amplifier circuit 3, and the first
Two-way communication between the first telephone line and the second telephone line is made possible, and the loss in both directions is compensated by an amplifier circuit 3 to make it the same as a normal communication state. Further, in response to the control signal of the called party response detection circuit 7, the conversation recording circuit 10 is activated and records the contents of the mutual conversation between the first and second telephone lines.

When the caller on the first telephone line goes on-hook to end the call, the on-hook detection circuit 6 detects this, opens the line circuits 2 and 4, and also stops the call recording circuit 1o, thereby stopping the device. will recover and go into standby mode.

Also, when the caller on the first telephone line goes on-hook during automatic dialing, the on-hook detection circuit 6 detects the call, opens the line circuit 2, and stops the automatic dialing circuit 9, and the device returns to standby. state.

Although not particularly shown, the called party on the second telephone line
Even if the caller on the first telephone line goes on-hook first, by adding an on-hook detection circuit to the second telephone line, the call circuits of the first and second telephone lines are opened and the call can be made. It is clear that the recording circuit 10 is stopped and placed in a standby state.

As explained above, according to the present invention, each time there is an incoming call on the first telephone line, automatic dialing is performed from the second telephone line,
It is possible to realize a call transfer device with a call recording function that can connect two telephone lines in an alternating current manner, compensate for bidirectional loss of the two telephone lines, and record the contents of the call.
