March 15th news, more than a year, there have been a lot of so-called "outbound" business advertisements on the Internet. The core business of these outbound call companies is to help merchants make their own marketing calls to mobile phone users, commonly known as "electric sales". Reporters went to many places to investigate. In a network technology company called Zhiyouqing Co., Ltd., the person in charge, Manager Tian, opened a system background for customers to test the operation. The words of an intelligent machine person in a dental hospital were presented on the computer screen, and each sentence had a corresponding trigger keyword. Once the consumer said the relevant sentence, the intelligent machine person would go to the corresponding reply content. "There are a wide range of AI types," he said. "This is pure outbound AI. In the early stage, AI is equivalent to infinitely close to a real person to help you call this phone." There is a kind of virtual operator, collectively known as "virtual merchant" in the industry. Virtual operators also sell 11-digit mobile phone numbers, most of which start with numbers such as 17 or 16, which are called "small" in the industry. The reporter learned that these companies engaged in outbound call business are all "small" purchased from virtual operators. These numbers do not have physical mobile phone cards and do not require real-name authentication.
