Got a call from this number at 3:04 am Eastern on August 30, 2009.  I didn't answer it.

received a phone call from 281-575-0012 and when I answered, there was no one there.  Disturbing and suspicious.

They called me at 4:37AM.  They left a voice message.  Something about the "new government legislation in my area" regarding foreclosures.

Received a phone call at 5:09 AM with no one on the other end.  Have tried to call back and the line is busy... go figure.

I received a phone call from this phone number at 5:09 am with no one there on the other end.  Extremely irritating and disruptive.
