A female netizen shared her experience of receiving "call and hang up" phone calls on a social media platform, sparking heated discussion. It turns out that these types of calls are part of a "number screening" mechanism, used to verify whether a phone number is valid, and then sold to companies, resulting in a series of subsequent harassing calls. To avoid becoming a target, netizens recommended using the Whoscall application, which filters incoming calls and displays the caller's identity, allowing users to decide whether to answer or not.

Common harassment calls in life can indeed be bothersome. A female netizen shared her experience of receiving a "call that hangs up as soon as it connects" on social media, sparking enthusiastic discussions among many netizens. However, these calls are not just typical scams or pranks as one might think; they are part of a so-called "number screening" mechanism, aimed at confirming whether a phone number is still in use, thereby establishing an effective database of phone numbers for specific businesses to use.

What does a call that hangs up immediately mean? A female netizen posted in a group indicating that she had received a call, which was disconnected the moment she answered. Out of curiosity, she searched online for the phone number and found that many netizens had experienced the same situation, with some unable to reach the number when they called back. This made her wonder, "Isn't it also expensive to make calls? Is there too much money involved? Or is there some other reason?"

The "number screening" mechanism confirms whether a number is in use. Professional netizens explained in replies that these types of calls are actually generated under the operation of a "number screening" system, which automatically dials numbers to test if they are in use. Once answered, the number is registered as valid, and it will subsequently be resold to other clients. This also leads to people continuously receiving harassment calls for loan promotions, which is truly annoying.

Countermeasures for immediate hang-up calls. To avoid becoming a target for these harassment calls, some netizens suggested downloading the Whoscall app, which actively filters and displays caller information, including suspicious calls that hang up immediately. This app is available for both iOS and Android users, and once installed, if someone calls, the screen will directly show the caller's identity, allowing users to decide whether to answer.
