The principle of call blocking:

Telephone interception is a common telephone interception service, which can help users intercept incoming calls or text messages at specific telephone numbers, so that users can get protection from numbers that do not want to receive incoming calls or text messages. Shielding function can sometimes be used to prevent these calls from disturbing users. It can effectively help users manage their inboxes.

The history of telephone monitoring can be traced back to the telephone network in the 20th century. At that time, enterprises were worried about being attacked by malicious phones, so they developed some phone interception services to avoid malicious phone attacks.

Later, when telephone calls such as fraud and harassment became common, these services were used for personal communication. At present, many mobile phone manufacturers are building this function, and users can buy better interception function from different applications and network providers.
