I got a call, no voicemail, called back and the number is not in service, just like Sumeet's comment. Also we both got the calls at about the same time.
Received a call from this number; answered.
A woman spoke, although she sounded automated in her responses, said she was calling about some debt, wasn't a sales call, and only needed two minutes of my time.
I'm not in debt. Never have been. Seems like some sort of scam to get your personal info.
