This number phone i answered it as it was after 9pm no one on the other line.

Called six times in a row, after I answered the first call.Is there a way to block this?

I had that call from this # a couple of times.  I checked my call display and I just put the volume to the highest on TV (it wouldn't hurt my  hearing because I am deaf!) and held the phone receiver to TV.  I haven't received that # since!  I keep hoping!  Before I registered on the "Do Not Call" list last Oct/Nov 2008, I used to receive average 15 calls every day.  Crazy, huh?  Then in January 2009 (from 20th to 29th), then I received the calls again till I got an idea to put the highest volume on TV.  Then I hardly receive any calls except for my friends.

I think all this flow of numbers, can only come from the phone company itself, as you see them changing phone numbers, and there are a great many phone numbers of them. Who can afford himself to have so many phone numbers, if it is not from a phone company itself, or from a few of their employees.

Have a look at the List of reported phone numbers:
