Abstract

PURPOSE:To attain direct talking between an originator and a receiver by storing the telephone number of an originating telephone set calling an absent receiver in a telephone transfer device arranged on the receiver side, calling receiver carrying a pocket bell and making the receiver dial to the telephone transfer device. CONSTITUTION:In the operating order of the telephone transfer system, an originator calls a receiving telephone set 2, and when a set time has been passed, the telephone set 2 actuates a message output circuit and sends a designation to the originator to dial the originator's telephone number without hooking on the telephone set. After the end of the message service, the originator hooks on the telephone set. Then, a pocket bell 5 is called by a receiver's telephone set 3 and the receiver's telephone set 3 is called by an optical telephone set 6 to dial automatically to the originator's telephone set 1. Thus, mutual communication between the originator and the receiver can be attained through said process.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention stores the telephone number of a call received from a caller who is out of the office or otherwise, in a telephone transfer device installed at a predetermined location such as the receiver's office or home. After hanging up the call, the call forwarding device can be used to call the recipient who is absent due to going out, etc., and the recipient can respond by calling the call forwarding device. This invention relates to a telephone transfer system configured to allow a caller and a recipient to communicate directly via this telephone transfer device.

2. Description of the Related Art Conventionally, answering machines have been used to convey the contents of a call from a caller to a recipient who is out of town or otherwise absent. When the recipient is not home, the caller records the caller's message and then hangs up.

Then, a device attached to this answering machine calls the recipient who is carrying a pager, and the called recipient calls this answering machine from outside etc. to check the recorded content, and then , it is used to contact the caller by calling them again.

However, with this type of answering machine, the caller does not have to call the caller again after confirming the recorded contents of the answering machine. I can't make calls. For this reason, it takes time to make contact, and business timing may be lost.

Additionally, most callers are not accustomed to recording their voice aloud, so they often hang up without recording their message on tape.

Moreover, with this type of answering machine, the tape and recorder head must be replaced regularly, and if the caller or receiver is in a remote location, it is necessary to have a lot of change on hand. There were many problems such as:

On the other hand, a telephone transfer system is used to transfer a call received from a caller to a recipient to the recipient at a predetermined location, such as outside the home. In this telephone transfer system, when the recipient's destination is determined, the telephone number of the destination is set in the transfer system so that the caller can respond while away.

If you do not know where you will be going out, ask the secretarial center etc. to transfer the call to the secretarial center and have the secretary answer the call. The person personally calls the secretarial center to confirm whether or not there are any inquiries regarding the reception.

However, with this call forwarding system, if the recipient changes their location, such as when they go out, the forwarding address must be changed each time, and if the forwarding address is not changed, contact with the recipient may be interrupted. Not only will there be nothing you can do about it, but it will also be useless if there is no one at the forwarding destination, such as the recipient. Furthermore, if the recipient fails to change the forwarding destination, there is a problem in that the recipient cannot confirm whether or not there is a call waiting to be received unless he or she inquires of the previous forwarding destination.

The present invention has been made by focusing on such conventional problems, and it stores the telephone number of a call made by a caller who is absent due to being out of the house, etc., in a telephone transfer device installed on the receiver's side. After hanging up the call, the call forwarding device calls the recipient who is not at the designated location because he or she is out with a pager, and the recipient responds by calling the forwarding device. This invention relates to a telephone transfer system configured to allow a caller and a recipient to communicate directly through the telephone transfer device by dialing the telephone number.

To achieve this objective, the present invention transmits a signal from a caller's telephone to a receiver who is away from home via a telephone transfer device that is equipped with two receiver-side telephones installed at the receiver's side. In a telephone forwarding system, the first step is for the caller to call one of the recipient's phones, the second step is to memorize the caller's phone number, and the second step is for the caller to call one of the recipient's phones. The third step is to call one of the recipient's phones from any telephone, such as when the recipient is out, and the other recipient's phone calls the caller's pager based on the memory output. and a fourth step of calling the telephone by auto-dial.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a schematic explanatory diagram of a telephone transfer system, in which reference numeral 1 indicates a caller's telephone, such as his or her own telephone, a telephone at an out-of-home telephone, and a public telephone. 2.3 is two recipient telephones installed at the same location, for example, at a predetermined location such as a company or home, and their relationship to each other is controlled by a control circuit that constitutes the telephone transfer device 4. has been done. 5
is a pager that the recipient carries while he/she is out, and 6 is an arbitrary telephone, such as a telephone at the place where the recipient is outside, the number of public telephones, etc.

FIG. 2 is a circuit diagram showing the specific relationship between the recipient telephones 2 and 3 controlled by the telephone transfer device 4. As shown in FIG.

In the figure, 11, 12, 13, and 14 are switching contacts that connect the public company line to the receiver's telephone 2 or 3, which is used as a normal telephone, or to the automatic transfer circuit, and are connected to the control circuit described later. Automatic switching is performed by line control relays 24A and 24B based on the output of 17.

In addition, the above-mentioned recipient side telephone 1fi2. 3 are connected to incoming call detection circuits 15 and 16, respectively, and to these are connected a control circuit 17 that controls the transfer operation based on the incoming call signal. Note that the line control relays 24A and 24B are
The operation is controlled based on the incoming call detection circuits 15 and 16.

The automatic transfer circuit selected by the switching contact 11.12 transforms the end of call detector 18, the dial signal generator 19 for generating a dial pulse or dial tone signal, the dial pulse identification circuit 2° and the dial tone identification circuit 21. It consists of 22 primary coils 23 connected in series.

The incoming call detection circuits 15 and 16 selectively detect a signal of a predetermined frequency input to the public corporation line, and input this signal as an incoming call signal to the control circuit 17 to perform necessary call transfer control.

When the telephone call end detector 18 picks up the caller's phone fil and the phone 6 at the place of departure, the exchange on the public corporation side processes it as the end of the call on the line.At this time, the line control relay 24A, 24B, the public company exchange transmits a 400H2 dial tone, so the end of the call can be confirmed by detecting this dial tone.

The dial signal generator 19 selectively generates a dial signal of a dial pulse or a dial tone of the caller's telephone 1 based on the output of the control circuit 17! The dial signal stored in the memory 25 is output when the reception of a telephone call signal from the receiver to the receiver's telephone ta3 is detected.

The identification circuit 20.21 detects a dial pulse signal or a dial tone signal input by a caller, and inputs either one of them to the memory 25 via the control circuit 17.

The automatic transfer circuit selected by the switching contacts 13 and 14 consists of a dial signal generator 26 that selectively generates a dial pulse or dial tone signal, connected in series with a primary coil 28 of a transformer 27. .

In this embodiment, the dial signal generator 26 outputs the telephone number of the pager 5, that is, a predetermined number signal.

29.30 is the secondary coil of the transformer 22.27, which are connected to each other via a bidirectional amplifier 31, and the signal from the dial signal generator 19.26 is passed through the bidirectional amplifier 31 and the transformer 22.27. The system is configured so that the caller's telephone 1 is called based on this signal.

Reference numeral 32 denotes a message output circuit, which is connected to the other secondary coil 34 of the transformer 22 and outputs a signal recorded in advance in, for example, a recorder or a voice synthesizer.

Note that 35 and 36 are in-use detectors that detect whether or not the other recipient phone 3 or 2 is in use when a call is made to the recipient phone 2 or 3; At this time, the dial signal generator 26 acts to call the person carrying the pager 5 who is out.

Next, the operation of the above circuit will be specifically explained.

First, a caller makes a call from telephone 1 to receiver's telephone 2. In other words, by rotating the dial disc or pressing a dial button, the receiver's telephone 2 is called.

This call time is within the set time (for example, within 3 calls)
If the receiver picks up the receiver's telephone 2 at this time, a normal telephone conversation can be made between the telephones 1 and 2.

However, if the phone is not picked up even after the ringing time exceeds the above set time, the message output circuit 32 will be activated and, for example, a recorder will be started.I am currently out of the office, so please call me. Masu. Please dial the shrine's phone number again without hanging up.
This message is played back and transmitted to the caller through the transformer 22 and the public company line. In this case, when the set time has elapsed, each switching contact 11, 12 is switched to the automatic transfer circuit side by the operation of the line control relay 24A.

Thus, when a caller dials his or her phone number,
The dial pulse signal identifying circuit 20 or the dial tone signal identifying circuit 21 determines whether the dial signal is a tone signal or not, and stores the result in the memory 25.

When the memory 25 completes its memorization work, the message output circuit 32 is activated again and the message “The customer's telephone number is ○○O-
It's O○OO's turn. If not, please dial again without hanging up. If it is correct, please hang up and wait for a while," the message is sent to the caller.

When the number confirmation is completed in this way, the conversation between the caller's telephone 1 and the receiver's telephone 1a2 ends.

After confirming the end of the call, the receiver's telephone 3 automatically dials a predetermined number (pager number), calls the pager, and disconnects the line.

Next, the person carrying the called pager calls the recipient side phone 1a3 by dialing from a nearby telephone 6, for example, a public telephone.

Based on this call signal, the signal previously stored in the memory 25 is passed through the control circuit 17 to the dial signal generation circuit 1.
9 and outputs a predetermined dial pulse or dial tone signal.

In this way, the caller's telephone tl 1 is called by this dial pulse or dial tone, and during this ringing, the receiver's telephones 3 and 2 are audibly connected;
A direct conversation can be made between the telephone 6 and the caller's telephone 1.

Note that an identification method using a voice recognition device for recognizing the above-mentioned telephone number can also be adopted. Further, switches 37a and 37b are switched by an incoming call switching relay 37.

By inserting 37c and 37d as shown,
Either of the telephones 2, 3 can be used for receiving or sending calls, and the end of call detector 18, dial tone generator 19.26, etc. can be connected to each transformer 22.27.
By connecting it to the secondary side of the circuit, the circuit configuration can be simplified.

FIG. 3 is a flowchart showing the operation sequence of the above-mentioned telephone transfer system, in which the caller calls the receiving telephone 2 in step a, and the time after the receiving telephone 2 receives the call exceeds the set time. step b of detecting; step C of normal conversation between telephones 1 and 2 if the recipient telephone 2 is picked up within the set time; and step C of detecting the message output circuit when the set time is exceeded. Activate the
step d of instructing the caller to dial the caller's telephone number without hanging up the telephone; step e of identifying the dialed telephone number and whether it is a pulse signal or a tone signal; Step f for storing any of the signals in the memory, Step g for sending a message to confirm this memory, Step h for the caller to hang up after the message call is completed, and a pager is called by the receiver's phone IIQ3. Step i: After confirming this call, the receiver calls the receiver's telephone 3 using any telephone tJI16, such as when the receiver is out of the office, and upon receipt of this call signal, the receiver calls the telephone 3 based on the signal of the telephone number previously stored in the memory. The step of auto-dialing the caller's phone 1 and the two recipient phones ta 2 during this call.

3 and step 1, in which the sender and receiver can communicate with each other through the process of step 1.

As explained above, according to the present invention, when a caller calls a receiver and there is no one at the receiver's telephone installation location, the caller dials through this telephone transfer system. The phone number of the dialed caller can be stored in the memory using a dial pulse signal or a dial tone signal. Then, by paging the recipient, the recipient calls the caller's side phone of the call forwarding system from any phone such as an office, nearby public phone, etc. You can automatically call the caller's phone based on the memorized signals and talk directly to the caller.

Therefore, the caller and the person carrying the pager can quickly contact each other anytime and anywhere.

In addition, there is no burden on the caller's side to record their voice like with conventional answering machines, there is no need to maintain and manage the recorder, and it is extremely advantageous in terms of handling and economy. It is effective.
