Received a call from this number: caller ID came up as Maryland. Caller left a voicemail: was an automated message stating that the federal government recommends protecting you home with a security system. If I wanted to participate I could let them put a sign in my yard and the home security system and installation would be free of charge. It provided the option to press a number to participate or be put on a do not call list. The message did not provide the name of the company that called.
