I'm not sure what was happening with that number in the past, but now it's a company called Shift. They help private car owners sell their vehicles. I happen to be looking on line for one and sent out my contact info. They called me. I did not recognize the number and googled it, ended up here. Out of curiosity, I called it from my office phone. Then a VM came in while I was dialing. It's a legit business. Perhaps in the past it was something else is my guess. I found using my work office phone to check out these numbers. I'm in the job hunting process right now so I get lots of calls from numbers I don't recognize. So rather than missing out on something I go that route to verify a number. Typically though if it's legit they leave a message. I posted this on 3/24/15.
