i did some beta testing for gemini voice solutions. they sell their equipment to cable companies. anyway, the hardware is pretty basic...it's the software that counts. i helped them identify a few gliches based on some of the calls i made. the calls were clear, quick connection, no worries. i like the aspect of getting voice mail and other features that verizon charges extra for. i also have some friends who got one of these units. we haven't discussed it, per se, but then i haven't heard any complaints either.
