The low end Vista Basic is not supported with any of our products, but Vista Home Premium, Business, and Ultimate may be used with our Speedy Dialer products, as well as our Piranha Predictive Dialer and new Falcon Telephone Notification System and Octopus Xtreme Auto Dialer. Please note that many of the older Dialogic voice boards do not work with Vista. All of our products still work with Windows XP.
