1.0 out of 5 stars Warning: Does not work with comcast, July 16, 2011

I purchased this voice modem to avoid paying the $7 per month lease fee to comcast.

Unfortunately, comcast will not activate these modems. I advise against anyone purchasing this modem if your attempt is to use it for comcast voice service.

Despite information posted on their website, and information provided on the phone by several representatives, as it turns out, the only voice/phone modem for purchase that works with comcast (as of writing this review) is the Arris MT722G.

In addition, comcast will not activate the voice modem except those purchased at special best buy comcast locations. And comcast will not activate used modems.

Not all best buy locations work. Here is a list from the manufacturer of the modem:

[...]

The cost is $150! And when I called the Dublin Best Buy location, I was told that they are sold out at all locations for over a month, and to call back in a week or two...

Apparently comcast makes it very, very hard to avoid paying the $7 per month lease fee on phone modems.

So I bought this one and tried to hook it up with comcast apparently they can set you up with this exact model, but you cannot go and buy this one and setup it up to work with comcast. They want you to buy the more expensive one they are selling with Best Buy for $150. The TM722G ENTA

The modem as advertised and delievered was perfect. Fast shipping and the product was just about brand new. But apparently (according to comcast) the only modem you can buy that works on comcast, you have to buy at a best buy store. Sort of does not make sense becasue on the comcast site they list this modem as compatable. Believe me their must be some sort of a hardware updgrade that comcast is not telling peopple about, because after 3 visits to the local comcast service center and hours on the phone and on-line with comcast tech support. Everyone at comcast has a diffrent opinion of what works and what doesn't. i ended up returning the modem and re-renting one from comcast so i could get back on line and have my home phone again.
only three stars for the vendor as i have not heard back from them on my refund in a couple of weeks. They were very helpful and friendly when contacted though.
