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 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.

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.
