We really like the Ooma. Yes, it’s VoIP. We stayed with comcast, preferring to drop the voice and cable and, instead, getting higher speed internet with them. It is working well, so far. We own the Ooma set, and we bought our own modem, so we won’t pay a rental to Comcast.
So did the change in modem improve your Internet service with comcast? We have been thinking of doing what you have.
