said by BiggA:CDV does have better quality of service than traditional VoIP. First, CDV is facilities based VoIP so there are fewer points of failure. Second, Comcast has the infrastructure in place to ensure quality of service (the connection begins at the EMTA and ends at the CMTS, where it enters the PSTN).
Plus a Generac generator to recharge the UPS and run other stuff in the house. Also, CDV is a total waste. It's just way overpriced VOIP.
Vonage and its cousins require the signal to travel over the public Internet (with many points of failure) to Vonage servers before it enters the PSTN. My alarm company says CDV is fine for alarms but they have had known failures with non facilities based VoIP providers.
I've experienced ImOn (when they were McLeod USA), Mediacom, Comcast, and Time Warner. They are much better than broadcast TV.
I have not and will not cut the cord.
