Guy with raspy voice who sounded like he was on drugs asked for me. I told him I thought he had the wrong number and asked who was calling. He started to talk and hung up in the middle of the first word. Caller ID said "wireless caller".
Love Tall Texan's reply ... ROF LOL ..... I have gotten to the point where I will use every 4 letter word I know or scream/blow a whistle into the phone .....
Since you're not a rocket scientist, I'll share a little information with you.
These calls are done with the use of autodialers. Because pretty much every phone number in the US is in use, they only have to set their machine to randomly dial numbers within each area code and they will be reaching a number that is in use.
If you answer, they know it's in use. They can either screw with you, or sell your number to a scammer who will call you, know that it is a valid number.
The phone service providers currently do not have the techonlogy or bandwidth (that mens the ability and resources) required to stop these people from doing this. By the time they identify where they are actually calling from (because technology often allows them to place a false caller-ID on the display) they just move to another number after they get shut down.
This has nothing to do with NSA, or Obama, or Bush or the government.
