Intuitive Technology's Evolution UC offers state-of-the-art IP-telephony features in a highly intuitive, low-maintenance PBX. With the Evolution UC small businesses, entrepreneurs and sales professionals can have a communications system that functions similar to the million-dollar PBX systems Fortune 500 companies use. The company sells products mainly in North America through VARs and directly on its Web site. Designed to enable a small business with little to no IT staff to benefit from the recent wave of telephony enhancements, Evolution packs features commonly available in high-end systems in a simplified, easy-to-use package. The days of calling your telecommunications supplier to enable another extension on your PBX are gone. With Evolution, you simply plug your phone into a standard network jack and let the system do the rest. All the configuration is done through an easy-to-use Web interface. Based on a open-source architecture, Interactive Technology has partnered with most of the major VoIP providers and integrated their service offerings directly into its product.
