About Phone Systems #

Estech Systems, Inc, better-known as ESI, is an industry leader in designing, manufacturing, and marketing business phone systems. The company's focus is providing innovative, power, flexible, easy-to-use, and cost-effective products.

This approach is well-exemplified by ESI's lineup of business phone systems, which utilize a single Communications Server. The single Server is a powerful tool that can be a traditional business phone system, an IP phone system, or any combination of the two. Best of all, the exact mix of technology that your business requires can be changed to keep up with your growth and changing needs.

Each ESI Communication Server office phone system combines multiple systems into a single unit that can handle such functions as voice mail, automated attendant (six levels, 100 branches), messages-on-hold, caller ID, automatic call distribution, and intelligent call forwarding. An ESI Communication Server business phone system is additionally capable of supporting more advanced, optional features, including the Windows-based VIP (Visually Integrated Phone), ESI Presence Management, ESI Media Management, ESI Bluetooth Voice Integration, and VoIP telephony.

ESI recognizes that your business needs powerful technology, but also that anyone should be able to use it. That's why all ESI office phone systems feature the company's famous ease-of-use. Your phone system will teach you how to use and program it and offer custom help whenever you need it. This simplicity of use, combined with feature-richness, reduces user frustrations, boosts productivity, and lowers costs while helping you create a strong corporate brand.
