Linx Services
As an ASP, Linx offers outsourced communications and messaging services to individuals, small businesses, corporations and government agencies. This enables companies to take advantage of the most advanced messaging solutions without incurring the capital costs of maintaining internal systems and equipment.

Linx' suite of easy-to-use, subscription-based web-enabled communications services give on-the-go people complete control over their phone calls, faxes and messages at any time, from any location. Linx services save time and money while eliminating the frustration of "telephone tag."

LinxConnect is a powerful, web-enabled one-number service that streamlines multiple communications tools (voice, wireless, messaging, fax) into a single local or toll-free number. By combining disparate devices into a single number, LinxConnect makes users more reachable and accessible while allowing them to better prioritize important calls and messages. LinxConnect features LinxWeb™, a robust personal communications web portal that allows users to listen to voice messages, view faxes, manage communications, and initiate real-time call connection via the web.

Linx also offers an ideal solution for organizations with growing communications needs. LinxOffice™ is a powerful "virtual" office phone system - a fee-based service that can be customized to meet a company's specific communications requirements. With LinxOffice, subscribers enjoy the benefits of a comprehensive office phone system without the hardware and maintenance costs associated with a PBX system.
