How do you know if your phone is being tapped? NOT by cops.?

Question

Is there a certainn sound or ?? that is obvious when a landline is being listened to by a spy device?? I hear an odd metallic sound when i talk on the phone and someone has mentioned that that happens when someone (in the neighborhood) is listening in with some sort of device. Creepy to think about but people can be strange...

Answer 1

if it is done correctly, you will never know.

if you hear clicks on the line, call your telco, tell them that there is a loose connection. They will stress test the line and tell you if there is a problem. Also, tell them you are having problems with data and that your line may be HALF TAPPED (very common in residental areas!) and the half tap is generating noise.

Answer 2

There is no way to know, since CO side switches are digital.

You will never know.

Everything is digital.

You cant do either analogue or digital encryption, but the receiving party will need the key and an encoder too.
