I used to do that once upon a time when I had more free time. I don't bother these days. If there is a call from somebody not on my 'contacts list', I will often let it go to voice-mail. Real people will leave a message, scammers won't. When I was trying for my 'personal best', the longest I kept a scammer online was two hours.
