Just do not answer. It's hard but never answer, don't call back, don't press 1. Ignore them
Takes a little while but eventually they give up. I get maybe 1 or 2 a week now.
Once you answer the phone or call them back they know they have a working number and they will sell it to other telemarketers.
So. Bottom line. Don't answer, don't try to talk to them....do not call does not work, too many to keep up with
Plus they are scammers and crooks, so they don't care .
Don't answer!
Received a call from this number that was ID'd as "Tennessee". I answered and it was a robo call. I think it was malfunctioning though, the message stopped talking, then disconnected.
Call from a robo dialer with spoofed caller ID. Selling alarm service.
They do not have a list -- robo dialers can spray out the entire 1000 numbers in an area code and prefix in minutes.
There are just enough live operators to come on line should a number pick up. You'll hear a transient when the switch to live operator happens. In the old analog systems, it would have sounded like a click. With digital systems the click is aliased to a "sproing" type sound. All these calls originate from call unscrupulous call centers that use a low-budget VoIP phone provider who does not care what crimes their customers commit using their VoIP service.
We must shut down these call centers; the criminal VoIP providers; and jail every one of them.
Until your Congress critter grows a pair, your stuck buying a blocker.
Frankly, I'm ready to go off-grid as far as telephone service is concerned.
As it is, I have my ringers turned off -- and do use a blocker.
