ESI Cordless Handset II

The ESI Cordless Handset II uses advanced DECT 6.0 third-generation 1.9 GHz technology to provide mobility to the user who’s constantly on the move in the office. Like the original ESI Cordless Handset models, each ESI Cordless Handset II provides its user most of the rich ESI feature set along with the convenience of a portable device — with the added benefit of increased range of use, thanks to DECT’s ability to support repeaters. This lets users continue calls while moving between different coverage cells throughout a location, using a process known as handoff that’s similar to how cell phones work. When you return to your desk, a touch of ESI’s Quick Switch Key lets you toggle from the lightweight, portable Cordless Handset II back to your full-function ESI desktop phone.

The ESI Cordless Handset II comes in three different versions:

Under DECT 6.0, each ESI Cordless Handset II operates on the 1.9 GHz frequency band, which has been specially allocated to support cordless telephony. Benefits of DECT 6.0 technology include:



The ESI C-Plus Executive supports only the original ESI Digital Cordless Handset models, and not the ESI Digital Cordless Handset II (which is for use with only the IP Server 900 and ESI Communications Servers). IVX C-Class supports no ESI Cordless Handset models.
