On what basis do you state that? I have Comcast voice and have had no problems from day 1. I have never missed a call, had one drop, or suffered poor incoming/outgoing clarity. Support is at least on par with the better VOIP services.

In fact, I am considering dumping Comcast voice for a more affordable VOIP alternative, however, nothing that I have experienced would lead me to characterize their service as "terrible", pricey would be my only negative (still cheaper than what my AT&T landline service cost).

Some VOIP services have issues when there are multiple devices accessing the system during calls...that is a non-issue for Comcast voice.

I'm going to 2nd what PeteC2 See Profile has said above. I've had Comcast Digital Voice since 05/18/2012, and have never had any problems with it. I've never had a call be dropped, had issues hearing the person on the other end of the line, or have them tell me they cannot hear me either.

As far as network load, I only have 3 desktops in the house (Mine, my uncles, and my mothers). My mom just reads e-mail, reads / posts things on FB, checks the weather (either from weather.com or Weatherbug), chats (via text) on AIM, and does some other light web surfing. My uncle does some light surfing and checks his e-mail. My system is probably the only one that would have any impact on the network, but even then, I would say I'm a "moderate" bandwidth user. So, if it is the case of households using "lots" of bandwidth that causes issues with CDV, then that could be why my house is not having a problem.

The price of CDV was less then what we were paying for a POTS line from AT&T as well. I forget the exact savings, but I believe it was around $15 to $20 a month that we are saving because we have switched from AT&T to CDV.

It runs on separate channels from HSI but the method is similar. It is VoIP via a private network. the home security services use yet another group of channels, and other future uses may get their own channels too or run as VPN's piggybacked on one of these other networks.
all invisible to you, and not using your HSI bandwidth.

Technically, it does not take away from the HSI bandwidth, but that is because a section has already been carved out and reserved for CDV, so it was never available for HSI. However, one could argue that bandwidth that _could_ have been used for HSI is reallocated to CDV, so it is taking some away. It is really just a matter of semantics. Everyone is right. Now, can we get back to the battery discussion?

I would think that the FCC or local PUCs would require battery backup as part of the service. OTOH, with the proliferation of cell phones, land line phones have become redundant. Of course, in a major power outage (let's use Sandy as an example), many cell phone towers will lose battery power after a certain amount of time (although some may have generators), thereby eliminating phone service there also. Even with CDV batteries, the Comcast plant must have power, and those batteries will also only last but so long. With POTS, only the COs need power, and they had diesel generators for backup, ensuring almost 100% phone service (as long as the lines don't go down, and they can get diesel fuel). All that being said, in my area, during Sandy, Comcast did not have any down time due to lack of power. The power outage was only 17 hours in my area. Other nearby areas (within a mile) were out for days. I don't know if Comcast was able to maintain service there or not.

Anyway, during Sandy, of course I didn't know the outage was only going to be 17 hours, and I discovered that the best use of my UPS was not to keep my Comcast eMTA up and running. Because I have an iPhone, I had (adequate) internet service on my cell phone, the best use of the UPS was to keep my iPhone charged (also charged it in my car). It uses way less power than the eMTA, so my UPS battery would last longer. As it happened, I never lost cell service. Bottom line was, although I have three batteries for my eMTA (which I rotate to keep charged), I never had a need to use them. If cell service died, I could have used the Comcast batteries as the final backup instead of the primary backup.

So, the question is- are eMTA batteries really necessary with the proliferation of cell phones?

I had zero issues with CDV. Call quality was excellent & no connection issues. The caller ID function was awesome appearing on my TV. I only dumped it to save money.

Simple Solution is get a UPS. Problem Solved.

Just running an inverter off the UPS battery and brick losses consumes a lot more energy than the MTA itself. You will need a huge UPS to see anywhere near the battery life of the tiny integrated battery even if UPS is doing nothing other than feeding MTA.

Charging a rental fee on something likely to be recovered many times over for MTA and punting on maintenance of same is like having your cake and eating it too - unfair and unprofessional in my opinion.

Or perhaps use a UPS that allows muting the "on battery power" audible alarm?

I agree. I own 2 different models of APC UPS units and both have a button on the front that you hit to display the various stats and say "hold to mute" I've not heard a single alarm in years if I didn't wish to. The fact the lights and AC are off in my room are all the alarm I need usually.

How long does the MTA battery last?

My CyberPower 1500VA 900W UPS supports a modem, router, switch & 1TB HDD providing 86 minutes.

I guess when a battery fails, you might as well ask for a new eMTA to avoid the charge.

Why? There are NO batteries being issued with eMTAs. There is a sheet in the welcome pack and in the SIK that gives the phone number to order and PAY for one.

When I got my Arris eMTA from Comcast, it came with a battery. Matter of fact, it came with a dead battery and the tech had to come back the next day to install a fresh one.

Are you saying that Comcast no longer supplies a battery with new EMTA installations?

To answer the "CDV is terrible" statement I can also beg to differ.

My mom's business has 3 lines on CDV since 12-9-11 and their hasn't been a minute of downtime (during business hours) since they were activated. Couldn't say the same for AT&T which there was always crackling, humming, or the line just plain out dying often times. It seemed like everytime AT&T was out in the alley one of the lines would go down.

I was considering switching to CDV at home when we got the BlastPlus package, but after remembering this BS with the battery thing I may as well just get the 9.99 for life plan with Vonage and use the money saved elsewhere. It's not worth the price if it doesn't even come with a BBU anymore!

That is correct. If you want one, you must buy it.

Also, most other VOIP solutions have no back up systems other than allowing one to have a cell phone designated for calls to go through when power is down.

I can live without battery back up on the eMTA as long as Comcast incorporates a cell-designated back up scheme.

Again though, my beef with that is since Comcast voice is an expensive VOIP provider, not providing batteries for their eMTAs appears a bit of a chintzy policy, and would be a contributing factor towards me considering a more economical VOIP solution.

If you are going to charge more, the best paradigm would be that you are giving more at that price.

Yep, cost is the only real issue that I have with Comcast voice as well. I am betting though that the convenience of having the same provider as tv and internet, combined with excellent reliability will keep them a viable option for many folks, and they still are less expensive than a comparable AT&T landline service.

You can permanently disable the alarms through APC's management software too.

So, everything that CDV touts about not sharing bandwidth with the HSI portion of your connection is false? Explain! That's contrary to the FAQ about it and what so many understood.

Here a simple Wikipedia: »en.wikipedia.org/wiki/Comcast_Digital_Voice

"Xfinity Voice is similar to VoIP, but differs in that it operates on a dedicated server and assigns priority to the information sent over the Xfinity Voice network, and also means that the information is not transmitted over the public Internet."

Although Comcast does not route calls over the public Internet, it does share use of their own network with Internet traffic. For example, whenever I was downloading large files, phone calls were garbled and Comcast could only solve the problem by installing a second modem because their voice modem does not implement QOS properly. I now use Vonage and although it shares use of the Internet, I do not have the same problem I had with Comcast.

Comcast recently raised my rates to $52/month including modem which is a lot more then Verizon POTS so I went with Vonage Basic Talk $9.95/month (not a teaser rate!). Better service and more than 80% savings!

That could be an underpowered eMTA not being able to processes high Internet data rates and phone calls simultaneously.

That is so not true. We've had CDV since last year and it's been crystal clear EVEN during intense HSI usage. In fact I have tested this myself and have had like 10 downloads going on Steam and streaming a movie on Netflix and the voice quality is perfect.

I think I read the CDV battery is good for 5hrs standby, 3+ hrs talk. That's for the "standard" (1/2 size) one. If you get an extended one (fully occupies the slot), I think it might be close to 9 hrs.

I'm guessing in event of an AC outage, some portion of the cable modem portion of the modem shut's done, maximizing power for the phone line. If so, then the internal battery would provide longer uptime than an external UPS.

I got new triple play server Feb 20, and had at least 4 different phone calls saying that since my service started prior to the Feb 26 policy change, I should have had the right to get a battery. Took FOREVER, but finally I got a nice agent who put in my request, and actually called to follow up that I received it.

The 1/2 size battery I got was pretty chincy for the $40+ you'd ordinarily pay. I'd hope that if I bought it outright (ebay), I could get either the full size one for the same price, or the 1/2 size one for cheaper.

I loved the way the bill made it sound like battery backup for phone service when the AC power was out was now an option that you could pay for (battery).

Does anyone know what their monitoring service is? I guess technically it wouldn't be that hard to have an automated system send an email to your Comcast email acct if it detects the battery is low.

Then you have an eMTA problem, as a second modem would do nothing in terms of expanding bandwidth. Not questioning your experience with it, just the conclusion.

I have never had any problem with multiple devices running, video streaming, interfering with phone calls.

I too however installed a second modem...but for a different reason. That way when I'm rebooting the modem and such, I'm not knocking my wife off the phone...good for domestic tranquility!
