Introduction
Call One provides innovative, comprehensive business telecommunication solutions designed to optimize your workplace. We take the worry out of telecommunications so you can concentrate on what you do best. Offering customized service and billing, competitive pricing, and unparalleled customer care.

Established in 1992 by CEO Craig Foster, Call One is dedicated to providing premium telecommunication services at competitive rates. As an antitrust attorney, Foster recognized the need to bring competition in local phone service to businesses of all sizes. His efforts led to Call One being the first telecommunication provider certified as a Competitive Local Exchange Carrier by the Illinois Commerce Commission.

Call One has since grown to become one of the nation's largest providers of voice, data, and internet services and systems. Our expertise and expansive network of superior carriers and leading edge technologies allow us to select the best product for each client. Our focus on customer service and a passion for our clients' success ensure that we address your evolving needs as if we were part of your company.

Call One is proud to be endorsed as the preferred telecommunications vendor by Illinois' leading industry and government trade associations. We were recently named to Crain's list of fifty fastest growing companies in Chicago, Inc. Magazine's list of the 5000 fastest-growing companies in the United States, and recognized as a workplace of excellence by the Chicagoland Chamber of Commerce.
