Leslie, there is more to it than just hanging up. The calls are disruptive, annoying, and sadly, even many established legitimate companies use insincere methods. For example, I've answered the phone many times to have a stranger ask:
"May I speak to the owner of the house?", to which I respond, "Who are you, and why do you want to speak with the owner of the house?"
"Are you the owner of the house, sir? I need to speak to the owner."
"I'm sorry, but who are you to call and start asking these questions? And you do not 'need' to speak to the owner."
By the way, this conversation is real.
Then there's the "courtesy call" excuse for making unsolicited sales calls. American Airlines has used that one on me.

Let me guess, Vulcan...the guy got a new number?
