Re: Lets see...
and as far as i know TWC does NOT offer battery back-up built in. they did at one time but had a problem and took them all out.
When i lived in Fremont OH my DP never had a backup. and if you didnt have a MOT eMTA you'd have problems with the SAs. |

I do not know about Canada but in the US the Time-Warner cable phone service is not VOIP. It is a proprietary digital phone service. There is a difference.

Yep, anyone who gets HSI (with or without CDV) and doesn't use a UPS with their cable modem or eMTA (and, of course, their computer) pretty much deserves what they get when the power goes out. |

There is no UPS here, the ARIS eMTA has it's own battery - just like my laptops.
The eMTA does NOT power anything else - not even it's own HSI modem!

Define "modem"
The ARRIS is an eMTA(enhanced multimedia terminal adapter).
When a power-outage happens, the "modem" side of it is dead but the phone side works.
CDV does not rely on the HSI to operate and no "modem" is active - no HSI.
Sure, with a UPS, you can probably get the other VoIP services to work, but many/most people with CDV or VoIP services do not have a UPS lighting up... anything.
Last power "interruption" we had, CDV worked fine.

Power can be a tricky thing - you can have power and the neighbors across the street not. Imagine if your Comcast would have always gone out if anywhere between them and you SOMEBODY somewhere didn't have power. |

but comcast cdv does not go thought public internet service. it goes thought there own network.. Comcast has more control over the service then like vonage. comcast cdv has normal 911 service other voip do not. comcast cdv work for alarms or voip dont. so people are paying a little bit more for more feature and benefits |

Not too surprising for DSL - Unless you're on an RT, there's no active equipment between you and the CO that needs powering. And I assume COs are very well poised to maintain power during a power outage.
RTs are, again, tied to voice services, so those are also surely designed to run during a power outage.
Cable has a lot of active equipment between the end user and the plant that needs powering. I remember back when I had MediaOne (no phone services offered), whenever there was a power outage, there was a predictable amount of time it took for their data services to come back up once power was restored. It was sort of like waiting for their computers to boot-up!

During many power outages, DSL worked fine, as long as I powered up the modem (car jumpstart kit + 400W inverter).

CDV doesn't need a modem ? Where is it 'plugged' in at your house ?
I will have TWC VoIP next week, but I've had VERY good service on Skype for making calls.
CDV is backed up by battery (I'm not very concerned about power outages - I have a car jumpstart kit that runs for ~6-8 hours powering modem + lights)
CDV does work in a power outage (as long as I powered up my modem, I had internet on DSL.. and VoIP)
I do agree that CDV/UverseVoice/TWC is a better overall product with QoS. With the current small VoIP's going belly up, I'll stick with TWC voice (next week after I drop AT&T) for a while.

CDV is backed up by battery - my modem is not. No modem - no HSI - no VoIP/ CDV doesn't need modem or internet. CDV does work in a power outage. My choice was for the CDV as opposed to third party VoIP solution. Yeah, CDV costs more than say AT&T CV or Vonage - it'll work though when *they* will not. I definitely agree with that. My previous AT&T VOIP service was good, but if the internet or power died, it died with it.
The price was creeping up. So, I went looking elsewhere and found CDV in a package deal, for only a few cents more then what my bill already said.
With it, I get 7 digit dialing again, battery backup when the power goes out, and working E-911.
To me, that is worth the slightly more money I pay CDV for. If it wouldn't have been CDV, I'd have evaluated my options and balanced features, price and uptimes and went like that.
CDV was the best choice all around and with what AT&T is doing now, it looks like I made the right choice as CallVantage looks to be going bye bye and I'd lose service anyway. |

You also don't need to play QoS games for your phone to work reliably. The bandwidth for it is provisioned separately from your HSI.
Your CDV also probably works with data services like faxes and TiVos. CallVantage could do it but requires "special" configuration, and there were warnings about upload bandwidth throttling and poor voice quality on their instructions. Some other VOIP providers can't do it at all.
CDV, and probably even U-verse Voice are more robust services and are priced as such.
For U-verse and AT&T DSL users, at least there was a little comfort in knowing that we stayed completely on AT&T's network to arrive at CallVantage's servers.
I simply don't trust some of the smaller VOIP outfits with my phone number. I don't want another SunRocket. CV may be being retired, but AT&T is a big company, I'm sure if they shut it down completely, we will be migrated off reasonably smoothly. I'm guessing AT&T doesn't want to let a bunch of voice customers just walk away, though. They will probably hang onto us until they can migrate us somewhere else. |

Agreed!
Third party VoIP use the actual HSI connection for the voice service - CDV does not.
Internet can go down, no third party VoIP is going to work - CDV most likely will!
CDV is backed up by battery - my modem is not.
No modem - no HSI - no VoIP/
CDV doesn't need modem or internet.
CDV does work in a power outage.

said by iansltx :Of course, CallVantage is similarly priced to "traditional" VoIP providers like Lingo, Vonage, VT, VoicePulse etc. So now if CV is cut off people will just move to other VoIP providers. They certainly won't pony up another $15 per month just to keep a telco brand name. I wouldn't be so sure. Many people have the choice of those same VOIP providers and yet choose to pay MORE for Comcast's CDV Voip product.
Brand names are very powerful and backed by lots of advertising. Many, many people choose the brand name product over a much cheaper generic product all the time.
