Received a call from this number. Disconnected after 2 rings. Didn't get to answering machine prompt

They called our office after hours.  I'm not sure what scam they are sportin' this time, but there's a string of numbers starting with 231-732 that try to sell anything from fake credit debt assistance to 200%+ interest loans on home computers.  This is also one of those call centers that'll hang up on you if you start asking the wrong sort of questions or ask to be removed from their calling list.
