In the vast majority of cases, that is, people who use normal landlines, yes, it does.Neither does a phone line.
I won't argue on that point. I'm pretty sure that I can't split my 622 -- the only box I have -- in half and loan it to my sister or brother or uncle.... The fact that I have to connect my 622 to my phone line is stupid, IMO. I don't order PPV, nor have any plans to, and in fact have all the PPV channels blocked or locked out.And why the need to "prove" where it is if you only have one box?
