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 Handset Brochure | |
