You won't need the phone line to activate the receiver. Worst case you won't be able to order PPV from the receiver - you'll have to call or do it online. I also have Vonage and I'm not sure if my HR20 has ever actually made a call or not. It's hooked up to the phone line, but there's no indication as to whether it has called or not. Also in the future when the Ethernet port is enabled, it's possible you won't need the phone line at all.fochs13 said:
