I specifically asked today for an official statement from Dish concerning the use of VOIP service as a phone line to your Dish Network receivers. The official word is this: As they stated on the Tech Forum, DISH Network receivers do not support a direct connection to VOIP, LAN's or cell phones. A dial tone from a land line must be connected in order to receive VOD, some ITV games or shopping services, or pay per view programming. Some customers may be able to connect the receiver to an adapter on a VOIP system which provides dial tone and successfully participate in the interactive TV and shopping services, but these types of connections are known to be very unreliable and inconsistent for Caller ID. Since DISH Network has no control over such services, we cannot provide technical support in troubleshooting problems with them. There you have it.
