Called before 9am on a Saturday. ID said Arkansas Call. I don't know anyone in Arkansas, so I picked-up and hung-up quickly.  They called back within 1 min. That would indicate that this was NOT a robocall.  The second time, I allowed the call to go to my answering machine in case the call was legitimate. No msg. was left (spammers rarely do - it gives the game away :-) ).  My notes indicate this number called me about a year ago.  The lack of comments here would indicate that it is not often used.
