IVX E-Class

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.

Big features; Big capacities

Each E-Class phone system combines multiple first-rate, feature-rich systems into one tightly integrated unit:

  • Business phone system
  • Voice mail
  • Automated attendant
  • Messages-on-hold
  • Enhanced Caller ID
  • Automatic call distributor (ACD)
  • Optional ESI-Mail™ unified messaging
  • Network-based VoIP telephony
