The landline phone always receives harassing calls and keeps calling. Is there any way to "blacken"?

Hello; You can install a Tencent mobile phone housekeeper to intercept power outages;

Can intelligently identify strange numbers and blacklist all harassing numbers;

It has powerful interception function;

Turn on the interception function, which can effectively and automatically intercept unwanted calls and text messages and join the blacklist;

The default setting is standard mode, which can automatically intercept incoming calls and text messages in the blacklist; thank you
