The trouble with calling them back is the Caller ID is usually spoofed, so if you call back and harass the person who answers, chances are good that you are harassing an innocent person who has nothing to do with the scam callers, and now YOU can be prosecuted for that harassing phone call.
By far the best course of action is to simply not answer any calls with numbers you don't recognize. If they are legit and want to talk to you, they will leave a message. If they don't leave a message, oh, well, guess they didn't want to talk to you after all.
