Linux PBX software, future versions will allow up to 10 lines, serving small businesses on more profitable recurring subscription plans.

I, for one, look forward to using the headline, "Ooma punches Comcast in the dick." This is irrelevant, though, to the phone experience facilitated by the current consumer-oriented wedge product, which is good enough to satisfy anyone who has a stable, fast internet connection, doesn't do faxing or alarm systems, and is happy with yet another machine on the home network. Try it, you cowards: it's currently on special at Amazon for just $200, with free shipping.
