ESI Communications Server

The ESI Communications Server family of systems is a powerful tool around which you can build your organization’s entire telecommunications strategy — and you don’t have to know it all in advance.

That’s because the ESI Communications Server can be a traditional digital business phone system, a fully standards-based IP telephony system, or any mix of the two. The choice is entirely yours, and the mix can easily change when your needs do.

Despite its long list of features, the ESI Communications Server — thanks to the 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 youneed help. There are several different models of ESI desktop phones. Each is a compact, attractive addition to any desk, designed to simplify your telecommunications. And the first-of-its-kind dPhone4 sports a 4-inch color display - the only digital business phone on the market with a color display - is ideal for most active phone users.

The 4-inch color display provides clear status indication for up to thirty-six (36) desiless programmable feature keys to allow users to see the information they need quickly and helping them achieve maximum productivity.

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