What Is a Plucking Machine?

Off-hook has two meanings. One is to pick up the handset of the phone or press the speakerphone. The state at this time is the off-hook state. The second is the abbreviation of "off-hook experience system".

When an analog line makes an outgoing call, the method for judging the other party's off-hook and the corresponding problems are as follows:

1. The other party picks up the phone and generates a popping tone. If the other party picks up the phone and does not speak, the system cannot know that the other party picks up the phone, and the outbound call system cannot achieve the purpose of outbound calling.

Problem: Most mobile phone and ordinary phone users have activated the ringtone music sound. At this time, if this method is used to judge the other party to pick up the phone, it will bring serious consequences. That is: the phone calls out, the other party's phone rings and sends ringtone music, the outbound system detects a popping sound and starts playing the outbound voice. At this time, the other party's phone does not go off-hook but the system thinks that the other party goes off-hook, and plays in advance After the voice is heard, when the other party actually picks up the phone, the voice is finished or half played. It is also useless to buy an outbound call system or automatic fax system.

2. The other party picks up the phone and the line generates a reverse polarity signal. Explanation: The telephone line needs to turn on the reverse polarity signal (voltage jump). When the other party picks up the line, the line generates a reverse polarity and the hook hangs again.

Question: It is absolutely impossible for a subscriber line to activate reverse polarity signals. Unless an analog trunk line is applied, applying for an analog trunk line is very difficult in terms of cost and difficulty. At the same time, most customers who buy outbound telephone systems basically use subscriber lines.

solution:

1.Sampling line voice

2.Use FFT algorithm to analyze the sampled speech

3. Analyze the sampled speech frequency and compare it with the audio frequency of the signal set by the sound card driver.

4. Determine whether the sampled voice is the sound of human speaking or music

5. Finally, make a comprehensive analysis of the sound to determine whether the other party (the called party) is off-hook, and start playing the outbound voice when the other party goes off-hook.

In particular: the solution of the ring back tone problem has greatly improved the sending success rate of the fax system. If this problem is not solved well, the sending success rate of the fax system is a big problem. ^[1]

Off-hook introduction

The off-hook experience system triggers the off-hook signal through light, magnetic or mechanical induction, and passes the signal to the mobile phone experience interactive marketing platform. When the customer goes off-hook, the self-service touch screen will automatically display the detailed information of the corresponding mobile phone model. The self-service touch screen uses an interactive physical occasion to apply a human-machine interface, which can facilitate customers to query various mobile phone information. At the same time, it can provide telecommunications operators to release: tariff introduction, tariff discount, business introduction, business experience, business handling, customer service, etc Features. The off-hook experience system uses free and open choices to meet customer shopping psychology, and enhances the customer experience impression through interactive video and audio experiences. It attracts customer attention and stimulates potential customer demand. This is mobile phone experiential marketing. ^[2]

The off-hook system can also combine marketing plans. Through the off-hook system, operators can release preferential plans in time, and can combine multiple packages to meet customer needs. The off-hook experience marketing system is also a system of inductive services, which can provide one-stop fast services to meet customer needs. The off-hook experience marketing system combines experience, marketing, and service organically and efficiently, thereby enhancing the customer experience, making it easier and more convenient for users to enjoy the self-service machine purchase service process, which will fundamentally change the traditional communication retail Sales model of mobile phone. ^[2]

Off-hook structure

Off-hook trigger signal feedback

2. Real machine charging

3. Burglar Alarm

4. Hardware control indicator working status

5. Customer off-hook information recording and analysis

6. Product introduction and customer feedback, etc.

7. System front-end display and background management

8. Product multimedia experience

9. Self-Buy & Self-Service

The implementation of the off-hook experience marketing system is through the combination of specific off-hook hardware electronics, software products, and storefront transformation and storefront operations, rather than simply deploying a set of props or simply re-beautifying the storefront. ^[2]
