then they'll need a way to disable the device when it's used outside your home.
Quote from pspr:
If it works on VIOP it won't capture much market until VOIP gets much better. At least judging from my experience trying VOIP with Ooma on Roadrunner cable. A nearly free phone service that wasn't even worth that. The Internet needs to get a lot better before it will be anything but a joke for phone service.
