I missed the call while at work (I don't make a habit of answering strange numbers while I am working). I called the number back when I had the opportunity, and the automated message stated that the number was temporarily out of service.
I rec'd two calls from this number. First call: no msg left. Second call: person gave a name of Greg and said he was calling from Bank of America regarding an inquiry I made, which I did not. I hit the end button both times.
