Just received a call from this number but did not hear anything on the other end, so I hung up.

Just received a call from this number but they didnt leave a message.

Me too.

Received a call on my cell phone, 11/1/2010 @ 5:20pm EST. No message was left and when I called back was told it is not a viable number.

I've had numerous calls from this number with a recording about health insurance.  Today I stayed on the line & pushed 1 to speak to a representative.  When I asked what company he is calling from he hung up.  I am on the donot call list & I reported it.
