Communications 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.

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:
