that is completely wrong... the technology has not changed, directv is not a 2-way satellite connection... period.
I have been installing both 1-way and 2-way systems for quite a while now, and I guarantee that they are not tranmitting off any D* dish.
If your sister is ordering ppv, the receiver has just not hit its limit yet, and will cut her off and ask for a phone line whenever it does.... i'm willing to bet that she is ordering ppv, but she has not been charged for them yet.
you seem to have a chip on your shoulder about Dish, and now assume everyone from that company is lying to you. Had you went with Direct instead you would be charged $5 for each additional receiver... but i guess a $5 additional receiver fee is better than a $5 "additional outlet fee" that E* charges.....
And E* equipment does work with many VOIP services.. I have mine plugged into Vonage, and have previously used Sunrocket, both worked flawlessly.
I don't want to sound rude or mean, but I don't like when people come on these boards throwing out wrong information. That just confuses people that come here looking for answers before deciding what service to go with.
