Hong Kong and Macao harassing calls are silent.

These are all deceptive calls from abroad. When he answered the phone, he stopped talking as soon as he heard something wrong.

We often get some calls from Hong Kong, and he says, he doesn't talk, and there is no sound after you answer it. This is a daily - happened thing. He is a liar. He doesn't listen to you as if he was cheated, so he doesn't talk.
