Received a prerecorded call on my direct line at the office while I was away from my desk.  The robocall began before my outgoing voicemail message was over, so all that was recorded in my voicemail was a perky female voice telling me to press a number to be put on their Do Not Call list.  I did a reverse-lookup of the phone number, and it appears to be a residential number in Medina, WA (just north of Bellevue, WA).  My assumption is that this is a scam call.
