I got Time Warner's digital phone in the new house MT.
I don't know if that's the same thing or not.
But, everybody I told I have it, have said it sucked!!
So far..... no complaints. But, it's only been a week??

Just got digital phone also (cox cable), combined with internet.
No complaints here.....but it has only been a few days.
Gotta say this though: right now I pay for internet, phone and tv what I used to pay for internet and phone alone with AT&T! (and this is no introductory rate either...)
I'm using Vonage for my 2nd line at home, but I have DSL through QWest. My neighbor has digital phone with Comcast Cable and likes it. Sorry, we don't have Charter here, but I know that Digital Phone (VoIP) needs a minimum of 128KB up to work well on a single call, and double that if you initiate a 3 way conference call.
