We got a call from this number today three times, at 6:37 pm, 6:57 pm, and 8:22 pm, and didn't answer. The caller ID was CAMBRIDGE MA. No voice mail message was left. There was no answer when I called back (our caller ID is hidden by default on outgoing calls). Thanks to Mike for posting that it is a political call from Bob Hedlund's campaign for mayor of Weymouth. Such calls for me are a reason not to vote for him.
They just called again today at 8:40 pm. I added the number to our call blocker. I was reluctant to do so, because the calls will end when the campaign is over, but it was getting very annoying.
