In 2018, the U.S. cellphone users received 47.8 billion robocalls. By the end of 2019, 44.6 percent of calls will be spammed. In this CNN Business video, you get to know how robocalls are not placed through cellphones but computers. Voice over internet protocol (VOIP) technology that you use for FaceTime and Skype is being used for these calls.
Interestingly, these robocalls are neither cheap nor easy to place. While the computer is generating a random number to call, it is also creating a masked caller ID that can be a real phone number. FCC recommends not answering calls from unknown numbers to prevent further spoof calls. Also, these activities are listed as illegal under the Telephone Consumer Protection Act. However, since any computer can generate these calls, it is difficult to impose the law. Heavy penalties have been levied against robocallers, though. Moreover, phone companies are finding out ways to prevent such calls.
