I would not suggest people try to waste scammers time, or do anything but hang up on them. A lot of calls that just hang up on you are putting out the feelers for phone numbers that have humans answering on the other line so that they know that's a viable target for attempting to scam. Showing any sign that your phone number belongs to an actual human just ups the chances that you're going to get an increased amount of phone spam, regardless of if you got the chance to waste someone's time or not. Also, people should be wary of saying anything at all the these suspicious phone calls, some of them try to get recordings of you saying some key words to make it easier to steal your identity. For instance, if someone asks if you are who you are by name and you say yes, then they've got decent confirmation that they've got a recording of a particular person saying "yes" which can be used against you in stealing your identity or credit card fraud.
