Who called from 4049371850

I keep receiving calls from this number. Most of the time, it is a fax line or automated message. I have stopped answering since I now recognize the number.

I have received 4 + calls from this number. I don't know anyone with this number. I don't get calls from this number as often as the other people who posted about this number have. I think this number started calling me a year or two ago, in 2011 or 2010. Today, Dec 12, 2012, is the first day they left a message. The message was silent.

they have been calling me for months when i answer its a machine talking about birth control and blood clots really weird i just dont pick up now but how do i block them

They called again. No message left. Calling my cellphone won't get me to answer.

I go the call but didn't answer.  I always research the number before I do.
