Can someone fill me on issues with dish 622 and phone jacks.  Rep on the phone told me reciever will not work if is it not plugged in.  I have HDTV and SD tv and I don't have landline.  I was planning to get 622 and use it as dual turner/DVR for my house.  Will 622 work without plugging it in land line.  
Thanks
