Who called from 3392051412

I answered the call, but nobody would talk.  My standard answer if I don't know the number is just, "YA".  That usually gets them and then if they don't say anything I usually say, "guess you don't want to talk".  I hang up just as I hear them say something.  Another greeting is "I'm on the do not call list.  This means you don't respect this list or you are a scammer.  Which is it"

I answered the call on my mobile and someone started talking then hung up. It sounded like a recording. I am not close to 65 yet, but I keep getting calls about Medicare. I marked this number to auto reject.

missed call no message let probably Medicare supplement  that I already have

Medicaid spammer, trying to steal personal info.

Didn't leave a message, assuming it's a medicare scammer out to bother my folks.
