I don't know what good that will do. I added my cell number years ago on the DO NOT CALL online list and have been getting annoying calls for about a year or so.

A couple of months ago, I was busy at work when my phone rang. I clicked on the blue tooth and said HELLO. This numb nut instantly began telling me how I could save more money and before he could explain how, I asked him, "Why the hell are you wasting my cellphone minutes with worthless bullshit?" He apologized and said that he'd remove my number from their sales list. But he tried to further explain his reason for calling but was met with an awesome disconnecting click from my phone as I closed my phone and continued working.
