Can the National Anti-Fraud Center app intercept harassing calls?

The National Anti-Fraud Center app is prevention, not interception. When harassing calls come in, the national security department associated with the software will send a message, prompting that the number is a fraud number. When answering the phone, be sure to pay attention to whether there is a prompt message to send. In addition, for the number stored in the fraud number information database. For new fraudulent numbers, there is no way to stop unreported numbers. You can only judge for yourself and decide for yourself.
