	ESI-Link uses your WAN or the Internet to join together up to 100 compatible ESI phone systems into one interconnected, IP-based system. While ESI wasn’t the first company to offer a multi-site solution, it was the first to offer one that unites the many advantages of multi-site communications (see full details) with the unique, high-performance features of ESI phone systems.

	ESI Presence Management is a hardware and software solution incorporating an innovative combination of RF scanning technology and ESI’s award-winning telephone systems. ESI Presence Management is offered as a basic doorphone solution for addressing basic entry and exit applications, and as an advanced supervisory solution utilizing RFID technology to provide access control and personnel location. Optional ESI TimeLine™ PC software maximizes the value of this amazing product. ESI Presence Management Brochure
	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
