Communication Servers

Ready to shoulder the load for your business

An 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 an ESI Communications Server — the ESI-1000, the ESI-200, the ESI-100, or the ESI-50 — 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.

The ESI-50L – our most popular small business system – is feature packed without IP functionality.

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; that's even more true for a backlit display, which is available on certain models.
  • 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.
