Communications Servers!

An ESI Communications Server is a powerful tool, 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-600, the ESI-200, the ESI-100 or the ESI 50 — can be a traditional digital business phone system, a full IP telephony system, or any mix of the two. The choice is entirely yours, and the mix can easily change when your needs do.

48-Key Feature Phone

An ESI 48-Key Feature Phone is ideal for most active phone users. Its large display and abundant programmable feature keys help you achieve maximum productivity. And, if you need even more programmable keys, it’s easy to connect up to two optional Expansion Consoles, each giving you an additional 60 programmable feature keys.

ESI Cordless Handsets

Each ESI Cordless Handset uses proven, reliable 900 MHz technology to provide mobility to the user who’s constantly on the move in the office. (Why 900 MHz? Because it passes through walls far more effectively than cordless telephony using the 2.4 GHz and 5.8 GHz bands, which are intended more for residential than workplace use.) You get the same rich ESI feature set as in the 24-Key Feature Phone — but in a compact, lightweight, portable handset. The ESI-exclusive Quick Switch feature makes going from your desktop ESI phone to your Cordless Handset, or back again, as easy as pressing a key.
