Got call on my cell.  Didn't recognize number so I did NOT pick up.  No message was left, so it must  NOT have been important!
FYI-  You should never pick up a suspected robocall/scammer; even to either "mess with them" or to tell them to take your name/number off-their-list.  The only thing that is accomplished is that you CONFIRM to the computer-dialing-program that your number is valid and can now be bundled and SOLD TO OTHER TELEMARKETERS!
