Abstract

PURPOSE:To give a time margin for liftup operation of a handset to a caller by providing a voice generating and sending circuit sending predetermined voice to an incoming side while the caller hooks off after the stop of a ring- back tone is detected. CONSTITUTION:When a caller makes dial operation and a called party hooks off, an exchange stops the sending of the ring-back tone. A ring-back tone detection circuit 5 detects the stop of the ring-back tone and outputs an instruction to a voice generating and sending circuit 6 via a transmission line 8 for the output of a predetermined signal. The voice generating and sending circuit 6 sends the predetermined voice to the transmission line 8 until the caller hooks off. The caller hooks off handsets 2, 3 during that time, the changeover of a switch 4 connects the reception line 7 to the handset 2 and the talking 17 with the called party is attained by the handsets 2, 3.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to the case where the called party goes off-hook in response to a call from the calling party, the ringback tone from the exchange is stopped, and the caller does not communicate with the called party after the calling party goes off-hook. The present invention relates to a telephone device with, for example, a speaker, which enters into a talking state.

[Conventional technology]

FIG. 3 shows the configuration of a conventional telephone device of this type with a speaker.

FIG. 3 is a configuration diagram of a conventional telephone device with a speaker. In the figure, 1 is a speaker attached to the telephone, 2 is a receiver of the telephone, 3 is a transmitter of the telephone, and 4 is a speaker 1 and a receiver 2. 7 is a receiving line for the signal sent from the exchange side to the handset 2, 8 is a switch for switching the
indicates a transmission line for signals sent from the transmitter 3 to the exchange side.

FIG. 4 is an explanatory diagram showing the operating procedure of the above-mentioned conventional telephone device. In the figure, 18 indicates the telephone side, 19 indicates the exchange side, 9 indicates the speaker switch on, and 10 indicates the dial tone from the exchange. , 11 is the dial operation, 12 is the ringback tone from the exchange, 14 is the response voice of the called party,
Reference numeral 16 indicates an off-footer operation of a speaker, and 17 indicates a call between a calling and receiving speaker.

Next, the operation of the above-mentioned telephone device will be explained with reference to FIG. A speaker who intends to dial off-hook using a telephone set with a speaker first turns on the speaker while keeping the handset on-hook. At this time, the receiving line is switched from handset 2 to speaker 1 by switch 4, and at the same time, the handset goes off-hook and switch 1
Dial tone 10 sent from speaker 1
is heard by the speaker through the . Next, the speaker performs a dial operation 11. Thereafter, when the exchange searches for the called party and initiates a call, a ringback tone 13 sent from the exchange is heard through the speaker 1 to the telephone 18 of the speaker. Then, when the called party goes off-hook, the ringback tone 12 is stopped, and when the called party's voice 14 is heard through the speaker 1, the speaker takes the handset off-hook 16, and the receiving line 7
is switched from the speaker 1 side to the handset 2 side, and a conversation 17 with the called party is started using the handset.

[Problem that the invention seeks to solve]

Conventional telephone devices are configured as described above, so the speaker must immediately pick up the handset and answer the telephone when the voice of the recipient is interrupted, but this action tends to be delayed. There was a problem.

This invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a telephone device that can give the speaker time to respond to the called party during on-footer dialing. .

[Means for solving problems]

Therefore, the telephone device according to the present invention includes a ringback tone detection circuit that detects a ringback tone, and a ringback tone detection circuit that detects a ringback tone. The apparatus is characterized in that it includes a sound generation and transmission circuit that transmits a predetermined sound to the user.

[Effect]

The ringback tone detection circuit according to the present invention detects a ringback tone sent from the exchange side. When this ringback tone is detected, the voice generating and transmitting circuit transmits a predetermined voice to the called party until the calling party goes off-hook.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a configuration diagram of a telephone device showing an embodiment of the present invention.
In the figure, 5 is a ringback tone detection circuit installed between the reception line 7 and the transmission line 8, and 6 is a ringback tone detection circuit that sends a predetermined sound to the receiving side driven by the ringback tone detection circuit 5. This is a sound generation and transmission circuit.

Note that other symbols are the same as those in the configuration of the prior art, so the same numbers are given and the explanation thereof will be omitted.

Further, FIG. 2 is an explanatory diagram showing the operation procedure of the above embodiment, in which 13 is the stop of the ringback tone detected by the ringback tone detection circuit 5, and 15 is the stoppage of the ringback tone detected by the sound generation and transmission circuit 6. Showing an automated voice response.

Next, the operation of this embodiment will be explained according to FIG.

As in conventional operation, when the caller performs a dialing operation 11, the exchange locates the called party and initiates a call.

A ringback tone is then sent from the exchange to the caller's telephone m18. This ringback tone will be heard by the speaker via the speaker 1. When the called party goes off-hook, the exchange detects the called party's off-footer and stops sending out the ringback tone.

At this time, the ringback tone detection circuit 5 detects the stoppage of the ringback tone, and outputs an instruction to the voice generation and transmission circuit 6 to output a predetermined signal to the receiving side via the transmission line 8. . In accordance with this instruction, the voice generating and transmitting circuit 6 transmits a predetermined voice to the transmitting line 8 until the speaker goes off-hook. In the meantime, the speaker can turn off the handset 2.3, connect the reception line 7 to the handset 2 by switching the switch 4, and enter into a conversation 17 with the called party using the handsets 2 and 3. .

In the above embodiment, the voice generation and transmission circuit 6 generates and transmits fixed words, but a control circuit may be provided so that words can be freely registered via the transmitter 3.

〔Effect of the invention〕

As explained above, the present invention includes a ringback tone detection circuit that detects a ringback tone, and a ringback tone detection circuit that detects a ringback tone. Since the present invention is provided with a voice generating and transmitting circuit for transmitting a predetermined voice to the user, the speaker has the effect of giving the speaker time to pick up the handset.
