Just got a call from 410-410-4101. Didn't answer it and they left no message.  Got a call about a minute later from an "Unknown Number".  Answered it but soon hung up.  Some sales call with a lady speaking some form of Spanglish.

I live in PA; been getting these calls for a few weeks now... but # has changed to 410-410-4010. Can hear noise in background, no message left. Usually some time in the next hour or two, an "Unknown Number" will call, same pattern. My phone number is unlisted and on the Do Not Call list... but this group of people are doing it anyway. Anyone report them yet?
