Answering unknown number calls on my cell phone like a receptionist really confuses scammers. "Good afternoon, thanks for calling!" "Hello." "Hi, who's calling please?" "This is Experian Security Services calling to discuss an urgent issue with your account." "Who are you trying to reach?" "I am looking to talk to the owner of this phone number." "I'm sorry, I'll need a name to help you." 30 seconds of silence. Call hangs up.
