I got this call, too.  My cell company blocks numbers when I request it.  I just remembered that!  I'm also getting calls from the 616 area code so I'm off to block both!

no message and when I try to call back it is disconnected. I blocked it.

I answered the call and a man said he was from Dish Network calling about switching us from cable to dish...  he seem unprofessional and lost in his words .. he ended the sales pitch when I said we already have dish.

Called at 5:17 pm, 1-19-2011.  Said he was with satellite TV.  Asked if I were using cable, Direct or Dish.  Then asked how many TV's I had.  Then asked my name.  I asked him, Who did you call?"  He said he was not allowed to give out that information.  He said I could talk to his supervisor.  I hung up.  There was a lot of back ground noise.  Kids maybe.
Call #2 from same number at 1:46 pm today, 1-20-2011

4:28pm  1-20-11:  Answered.  A lot of clicking then hung up on me.
