All, Thanks to some tips and discussion on this forum, I was able to get my Philips DSR-708 Tivo Directv unit working through Sunrocket Internet phone service. First, let me say Sunrocket is fantastic service. I have been extremely pleased with their service and product. Anyway. Following a tip I saw in another thread - here are the dial settings: Set Dial In Number: (Just choose your local area code or previous local #) it doesn't matter what is in here Set Dial Prefix: 7039409705,,,,, Set Call Waiting Prefix: None Set Tone/Pulse: Tone Set Phone Available Detect: Off Set Dial Tone Detector: Off This works because it basically gets a dial tone, and send the "Dial Prefix" before it tries to dial the actual number. The (703) 940-9705 is the local dial in number for Tivo in Falls Church VA. (This is where Sunrocket patches the internet calls through to the actual real phone lines - at their HQ in Virginia). It must be the cleanest connection - but for some reason it works fine. Hope this helps anyone else out their who is having issues. Mine finally works now. PS I am also using the RCA Modem/Phone extender using the wall outlets - so that makes it even harder to get a clean signal. Cheers.
