Who called from 6477252914

Just got the call too. Ignored it because I'm not expecting any calls from that area code. No message left.

Also just got a call from that number - when I said, "hello", they hung up.

The number calls our house at least once every day.
Very annoying. There is no reply when we answer.

Got the call aprox 30 minutes ago.  Did not answer as the number was not familiar and they did not leave a message.  When I called it back the message indicated "the number you have called is not in service",  Strange.

It's an automated call from Toronto. It starts by stating that it's conducting opinion research on "our nation's debt crisis" and, in return for completing a short survey, you will receive a cruise to the Bahamas (air fare and a small port charge will, apparently, be extra).

Pressing '1' continues to the survey, pressing '9' will supposedly permanently delete your number from their database. Let's hope.
