How Does Call Blocking Work?
阻擋來電是如何工作的？
Every time you place a phone call, the number you are calling from is transmitted along the phone line as an unrecognizable series of beeps at different frequencies. Even when your caller ID box reads "blocked," these numbers were still being sent to recipients and just hidden by companies themselves for privacy reasons.
每次你打電話時，你的電話號碼都會以一連串無法識別的不同頻率的蜂鳴聲沿著電話線傳輸。即使你的來電顯示框上寫著 "已封鎖"，這些號碼仍然被發送給接收者，只是被公司自己以隱私為由隱藏起來。
