I installed an Ooma IP-phone a couple of weeks ago and it seems to work fine. Once you get past the expensive purchase price ($450 or so) it's seems to be a good long term solution to phone service in the home. You get a phone number in any areacode you want and all domestic calls are free. No taxes or add-on fees like wire-line phones. 911 service has some limitations but I've never used 911 in my life from my home phone.

If it continues to work well, I'll be discontinuing my current phone service, which is also IP based but on a private "internet", and furnished through Comcast cable at around $30 a month.

Anybody else trying Ooma?
