ESI’s 48-Key Feature Phone

Powerful — but friendly

Despite its long list of features, an ESI Communications Server — thanks to famous ESI ease-of-use — is a phone system you’ll find friendly. It 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 desktop 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 an ESI Communications Server’s enhanced capabilities.

If you’re frequently on the move throughout your workplace, an ESI Cordless Handset is the easiest way to stay in touch with other system extensions, not to mention your voice mail. The ESI-exclusive Quick Switch feature makes it easy to go from desktop extension to Cordless Handset at a moment’s notice; just press a key.

Easy to choose; easy to use

Regardless of the model you choose, any ESI Communications Server 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 each ESI Communications Server’s unique integration provides call processing efficiency and cost savings that previously were impossible.
