Communication Power that Your Office Needs — Today and Tomorrow

We work with you to find the ESI Communications Server that will be just right for your communication needs.

  • A highly advanced, expandable phone system with extensive, unique call-handling features.
  • A flexible architecture that fully supports both digital- and IP-based communications.
  • Superior voice mail capabilities with exceptional features and messaging options.
  • A multi-level, highly customizable automated attendant for call routing.
  • Automated call distribution (ACD) to maximize convenience for your callers.

Grows with your business — intelligently

Whether you have many users and outside lines, just a handful of each or something in-between, an ESI Communications Server grows with you. For modest call-handling needs, a smaller system may do. From there, larger ESI platforms allow additional growth and customization. The built-in voice mail maximizes both call-handling and voice mail storage. As your communication needs grow, you can easily and cost-effectively add lines (including high-capacity trunks), phones, and special options — if and when you need them.

Flexible enough to do the job, now and in the future

An ESI Communications Server is a fully flexible platform. It can be digital-based, IP-based, or combined (digital-and IP-based) depending on your needs. ESI was one of the first in the industry to create purely IP-based phone systems, as well as to add IP capability to digital systems.

All of the ESI desktop phone models, both digital- and IP-based, provide advanced phone features. This lets you tailor your phone selection to your needs. ESI desktop digital phones come ready to plug into any digital phone jack.

Save yourself the trouble and expense of wiring new phone outlets

ESI’s desktop IP phones work from anywhere on your network. They also can go to most remote sites with broadband service, so executives and others can work from home while still having access to the office phone system and all the ESI features they are accustomed to.

Do you have multiple locations?

You can connect up to 100 IP-enabled ESI systems on an Esi-Link™ network for more convenient communications and significant long-distance savings.
