I have comcast for my cable TV and use it as my ISP...
I love the speed test for Internet smartzone usage tv listing nvq. I'm not crazy about the New Comcast Customer Service Remotes will give you endless runaround if you try and downgrade your service. Period! It takes lots of insisting.
I would not use them for my phone service. I used to have Verizon...I got really, really tired of the high prices and constantly added new fees.
I started hearing about VOIP...read whatever I could get my hands on..
Cancelled my Verizon phone service that was supposed to be costing me 40 bucks and change, per month.. in truth, it was a lot closer to 50 bucks.
I chose Vonage VOIP... there are only 2 plans...mine costs 14.99 per month for 500 minutes, that includes long distance. The second plan costs 24.99 for unlimited minutes. That's the whole point with VOIP... there is really no such thing as a long distance. Vonage is starting to include lots of European cities as free calls with the 24.99 plan...I believe, that as they add more customers, all long distance calls will be included, no matter where in the world they are.
Anyway, I don't turn my computer off very often...and when I do, it is usually overnight, just to give it a rest.
Because of this... I had to check to see if my phone worked while my PC is turned off. It, certainly, does.
Comcast VOIP is priced way to high..IMO, they are counting on folks who haven't done research into VOIP. They know lots of folks will choose them simply because they use them for cable TV and Internet..and like the "ease" of one bill and get taken in by the multi use discount. That small discount doesn't begin to touch the savings from using Vonage. Likewise, Comcasts digital "regular" phone service is just as overpriced as the other phone companies. Verizon also has a bare bones phone service...not that you will ever, ever hear about it from a CSR...and if you mention it they will try and tell you it doesn't exist.
Anyway, I'm thrilled to have cut the *cord" from high priced phone companies. It is wonderful to see my monthly phone bill is 17.48 (total price with taxes and federal fees). Btw, both plans include lots of features.. free voicemail, caller ID, call forwarding, etc.
Btw, Vonage VOIP service uses your regular, normal phone...it is a quick (and small) snap-on type device that attaches to your modem and PC.. comes with very easy illustrated instructions.. and there is no difference, at all, in sound quality. You might want to check out the website.
