The ESI Communications Server 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.

Powerful — but Friendly
Despite its long list of features, the 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 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; that's even more true for the backlit display you’ll find on most models.
- The dedicated function keys (so you don’t have to memorize codes) give you more ease of use, even with the ESI’s enhanced capabilities.
