Got a call from this number and, being that I'm in the 207 area code, I answered. Same spiel about medical alert buttons...it said to press 5 if you didn't want to receive calls from them. That's what I did, so we'll see if they call back or not.
The company is called CHOICE ONE COMMUNICATIONS, INC. out of bangor, maine. No idea what they do. http://www.reversenumberdatabase.com/searchResults?phone=207-631-2337
