I currently have two 510 DVRs and one 522 DVR. I also have the Vonage VoIP phone system. I assumed I could just plug in the receivers to the Vonage box and be done. Nope. When I do the phone test via the diag menu it passes. When I try to dial out it fails. I think this has to due with Vonage and other VoIP being true digital. A modem works by converting digital to analog and at the other end being digital again. I assume anyway. I also assume that a digital signal cant carry analog well. I have searched the forums and found incomplete answers to my question. Does anyone have a succesful solution to using Dish Network and Vonage?
