Who called from 6477254284

This number calls me twice a day. The line is quiet for a few seconds then hangs up.

this number kept calling my house.  when I said hello, there was no answer. I called back and got a recorded message and an option to add my 10 digit number to the 'do not call' list.  I didn't request them to call me, why do I have to take extra effort to add my number to something
