@Pippinwhite -- I hear you. This really gripes me because I'm the one paying for the phone line, and in my opinion, I ought to have complete control over who calls me and who is blocked. War dialing is unethical and should be a Class A felony. Maybe that's overstating it, but I have to hear phones ring all day at work. I have no interest in them ringing at my home in the evening.
I'm glad my phone company allows me to block numbers on my landline. I'd go nuts if they didn't.
