Why do cell phone housekeepers intercept phone messages?

The mobile phone housekeeper always intercepts many calls because you set interception rules. The mobile phone housekeeper will intercept some harassing calls or sales calls according to your interception rules. If the number is retrieved through online search and recognized by many people as harassing calls or sales calls, it will be automatically intercepted. There are also some blacklisted phone numbers you designed, and automatic interception will be set. If you don't want it to be automatically intercepted, you can cancel the blacklist interception rule at the mobile phone manager's house.
