Lightyear Network Solutions is emerging as a pioneer in the transition from traditional phone systems to VoIP. High quality calls is priority #1, with a direct US based support system to back customers up when it's not. Because of the transition to VoIP that will be happening over the next few years, many companies are putting the marketing dollars before the network. Lightyear is using the direct marketing model, and it's beneficial in ways other direct marketing companies have failed; by providing a recurring stream of income, and allowing the network to build itself with available money. Because of this, people are spending the time educating, understanding, and transitioning to VoIP with a better understanding of where the technology is going. Feel free to contact myself or the company for more information.
