ESI
ESI is a privately held corporation with headquarters in Plano, Texas, just outside Dallas. Rapid growth, stable management, and innovative technology have characterized ESI since its founding in 1987.
ESI designs and manufactures high-efficiency, low-cost business communications products. These products have earned numerous product awards from industry publications.
ESI develops business communications products targeted to businesses of various sizes (with an emphasis on small- and medium-sized businesses), and markets those products through a diverse Reseller organization that includes a broad cross-section of telephone interconnect companies and independent telephone companies throughout North America.
As an original equipment manufacturer (OEM), ESI has built private-label versions of its products for some of the world’s leading brands in telecommunications, including Comdial, Samsung, Executone, and Code-a-Phone.
ESI products are used by major companies such as:
- Coca-Cola
- Hertz
- Chase Manhattan Bank
- Best Buy
- Holiday Inn
- Century 21 Realtors
- Blockbuster Video
- Fleet Bank
- Office Depot
- Hampton Inn
- Advantage Rent-a-Car
- Farm Bureau Insurance
Additionally, ESI products have been installed in over 200 nationwide offices of one of the largest agencies in the United States government.
Because ESI is an independent U.S. manufacturer that designs its own combined business communications systems, each ESI product is aggressively priced and possesses unique, leading-edge features. Market agility allows ESI to meet industry needs more efficiently than larger companies can, and advanced product design gives ESI a competitive edge over more limited competitors.
Cutting-edge technology, award-winning products and a progressive vision define the ESI difference.
