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),
