ooma Hub - VoIP Phone Device with No Monthly Phone Service Bills

Watching the video at http://www.ooma.com/ it appears that unlike Vonage, this box allows you to continue to use the traditional land-line using the same phone number. This is good because, for 911 calls and also when the internet is not working well, there is an option to receive inbound calls with the same level of quality as a land line. Further, many basic land-line services are typically $10.00/month while the national calling plan significantly increases the rate. With ooma, it's possible to retain the quality and reduce the quantity of money to spend.
