Advertisements All, I am coming back to D*TV after 1 year of horrible cable service. I am activating one of my 2 HDVR2 boxes, they were only used for about 5 months before I shut them off. I now no longer have a phone line as I am on IP Telephony. Will this unit work without having a phone line? Will I need to do any setup again after I hook it up? Any thoughts?
