Got a call from this number today at exactly 12 Noon on work phone (I never give out this number, nor do I list it as mine). Didn't pick up as I did not recognize the number, didn't leave a message.
Received a call at work from this number, no message was left. I called back and it's the same as what Charles posted above: "Recorded announcement stated it was an insurance company with "plans starting at just $15 month" and "Press 1 for more information or 9 to be removed from my list.""
