Got a call from this number. They didn't leave a message. I found this link that says it's likely a phishing scam of some sort. (http://www.whocalledme.com/PhoneNumber/412-339-1649) They apparently asked other people for their name, address, last 4 of their SSN, etc, but wouldn't say where they're calling from. I tried calling the number back and it said, "Your call cannot be completed at this time." I don't know. I'm not worried about it.
