                               Our Beginning
In January 1984, the Bell System divested itself into seven regional operating companies, with AT&T becoming primarily a long-distance provider. Opportunity presented itself in a number of ways. Competitors soon came to market with long distance alternatives. Manufacturers followed with equipment options while service companies sprang up to fill the need.

Business Telephone Supply was founded in 1984 by Raymond Fuller to help businesses put all the pieces of the puzzle together. Originally known as Business Telephone Supply, the company has been recognized as being THE leading provider of telephone systems in the Dubuque area market.

Ray’s sons, Lou and Steve Fuller, joined Business Telephone Supply shortly after the business was formed and brought with them an entrepreneurial spirit and desire to expand on the early success of Business Telephone Supply by broadening their reach into the market.
