Every time I have answered this call it has been dead air! So annoying!! When I looked up the number it said it was for the Democratic party, John Hickenlooper and that group. I can't wait for the political season to be over!!
Political, charity and some survey's are exempt from the DNC . What you need to do is tell them you do not want to receive their calls, and make sure you do a opt out with all the political parties. Then, if you receive calls, go that persons web site and under their contact us page, write them and tell them to place you on their internal dnc list and also there is a political do not call you can sign up for. I did and also tell them to use that list and give them the url for it. I have not gotten any calls for years now. Not even political survey's. So it does help to follow the steps.

The other thing that will help, if you have a cell phone, if it doesn't already have call blocking, there are free call blocking apps online you can get for some phones. If you have a land line, google call blocking devices. There are phones also available with call blocking but they do not hold as many numbers as devices do. Many of the devices run around 50.00 or less. If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number
