Received 1 and I suspect 3 more calls from this number on 1/06/2010.  The last call came after 9 PM.  The name of the company was not included.  I answered the last one, which I ordinarily do not do, a man answered asking to speak to me and when I said, speaking, he hung up or the line went dead.  After that, the phone rang 3 more times but I didn't answer.  I have now placed call blocker on my phone.  I also reported it to the "do not call registry" since I am on it.
