48-Key Feature Phone

An ESI 48-Key Feature Phone (backlit version shown, right) 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.

There are two versions of the 48-Key Feature Phone:
48-Key Digital Feature Phone

Connects to our high-performance phone systems to provide an equally high level of performance.

48-Key IP Feature Phone II

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.

ESI Cordless Handsets come in two sizes (small and large), and there are three different versions for each size:
