iPhone Robocalls

I think Robocalls are the bain of every iPhone users existence! They seem to be getting worse too. I get them at home as well, but they are especially annoying on the iPhone because the iPhone seems to ring forever. I have tried several ways to deal with Robocalls, but have not come up with an effective plan until I saw this video by Gary Rosenzweig. It really makes a lot of sense, check it out.
