Got call on my cell.  Did not recognize, did not pick up.  No message was left so I guess that it WAS NOT IMPORTANT.
FYI-  You should NEVER pick up suspected telemarketer/scammer calls; even to "mess with them" or to tell them to take your number OFF of their list.  The only thing that is accomplished is that you CONFIRM to the computer-dialing-program that your phone number is valid and can now be SOLD TO MORE TELEMARKETERS.
