Who called from 7812079011

We got a call from this number today at 4:01 pm. The caller ID was WALTHAM MA, and it was blocked by our call blocker. Due to numerous other such calls, our call blocker blocks all calls with this caller ID. Apparently this is a new number for these lowlife coprolites. They have also used 781-207-9044. When I called back (our number is hidden by default on outgoing calls), I heard a recording which said "press 9 to be put on the do not call list".  We are already on the national and state do not call lists, so the call was a violation of the law.

Received a call from this number, no message. I'm from Lynn and live in Waltham so it's an interesting attempt to robo-call

Called, I didn't answer, no message

Recieved call, did not answer, no message left, now blocked.
