We got a call from this number today at 3:21 pm. The caller ID was SPRINGFIELD MA, and it was blocked by our call blocker. Due to numerous such calls with this caller ID all calls with it are blocked. When I called back (our number is hidden by default on outgoing calls), I heard a recording which said "Thanks for calling. The survey you were called for is now finished. If you would like to be removed from our list for future such calls, please press 9." Apparently they are disguising themselves as a survey. Thanks to all who posted information about this number.
