Robocaller.  "Limited time offer on Viagra!" was as far as they got before I hung up on them.  Call came in on an alternate line that has a number that is NEVER given out to anyone...I figure that they were just mass dialing entire banks of numbers.  Blocked the number via the Ooma, and also reported to the Federal Trade Commission and FCC via the DoNotCall web site.

Viagra calling with a 10 day free sample!
"Press 5 for your number to be removed."
This one actually gives you the automated message when you call the number back.
