Caller ID says "MASSACHUSETTES" (extra e is their's not mine).  They leave no message.

I call after hours (using *67 to block my number).  The phone "message" on their answering machine is just about 2 minutes of silence.  Then it hangs up on you.

So we have a spoofed caller ID and the inability to be called back.  Smells like a SCAM to me.

I have been getting a lot of these calls lately.  All have a caller ID of MASSACHUSETTS with or without misspellings.  All unreachable with a call back.  Mostly from 508 but a couple from 781 area code.
