Calling me is a privilege, not a right. And because certain corporations have abused it I'm going to fiddle around with my phone until I can make it stay silent when a person with "no caller ID" phones me just as I already have it set for when certain corporate numbers call me. This is the next to last step in making me completely happy with my phone. I've already got it set so that when Comcast, Xcel, or the DNC call me the phone does not actually ring. I've no time or patience to deal with robocalls from organizations of whatever sort. They can go to voicemail.
