I've been receiving calls from this number over the last few days with no VM. Decided to call the number back from my office and it's just an automated messages that says "Please press any digit to be removed from this list. This could take 24 to 48 hours".
I think that this is a Hartford area code they call me all the time to ,even after I had slammed the phone down on them a few times to stupid to take the hint I guess
