Who called from 6672182239

Call came in on january 5th 2016 at 10:02 AM and Caller ID displayed "Baltimore MD 667-218-2239" of course no VM was left. Since no VM was left, the call wasnt important to begin with.
I have no idea who they are or why they called.

Same experience as sheldon:  called 2016-01-05 at 11:50a as "Baltimore MD ...", and no voice mail was left.

Rec'd call, it rang through because of an auto-answer feature I use while I work from home. Nobody on the other end. I did not make a peep and hung up promptly. Hopefully the act of connecting doesn't open me up for something bad.

Called 1-5-216 at 6:28  Left no voice mail.

CID: Baltimore MD.
Left no msg.
*67'd the # and it's our old buddies the F.O.P.
