Who called from 3122833786

I answer they hang up.

Got a call - did not answer. no voicemail was left.

Received call.  Yet another spam/scam/telemarketer.  You would think by now I would be smart enough not to pick up an unrecognized number, but alas...  another waste of time and energy.

Came in on my cell number, which I never answer if there's no known ID. I do however, turn the number into local, county, state and federal authorities.

Calls cell and doesn't leave messages. Suspect it's a wardialer. Whitepages lists it as a voip.
