- but friendly

Each ESI E-Class phone system says, “Good morning.” It teaches you how to use and program it. It reminds you to change your personal greeting after a trip. And it stands by, ready to assist you whenever you need help. There are several different models of ESI Feature Phones; each is a compact, attractive addition to any desk, designed to simplify your telecommunications. Here are just two examples:

  • The display is large and easy to read.
  • The dedicated function keys (so you don’t have to memorize codes) give you more ease of use, even with the enhanced capabilities of an ESI E-Class system.

And each ESI IP Feature Phone works with either IP E-Class or properly equipped IVX E-Class systems, making it simple for an IVX E-Class system to migrate to an IP E-Class system if you desire.

Easy to choose; easy to use

Any of these E-Class All-In-One Digital Phone Systems is an easy choice over other phone systems. Its ease of use and feature-richness reduces staff frustrations, increases productivity and enhances your corporate image. And an E-Class system’s unique integration provides call processing efficiency and cost savings previously impossible.
