ESI Feature Telephones
Estech Digital & VoIP Business Phones
Having an ESI phone system lets you choose from among a variety of attractive and highly convenient Feature Phones. Each is a great addition to virtually any office decor, but it’s far more than just a “pretty face.”
Each desktop model whether 48-Key, 24-Key, or 12-Key Feature Phone has a sealed membrane below the keys to make it virtually spill-proof; and the sturdy four-position angled base lets it fit on any
desk or counter space so you can easily see the status of the display and keys. Each ESI desktop phone also can be wall-mounted.
ESI’s Cordless Handsets provide mobility to users who are constantly on the move in the office. Each compact, lightweight Cordless Handset provides the same rich feature set as ESI’s 24-Key desktop Feature Phone, plus ESI’s exclusive Quick Switch™ for maximum ease when switching back and forth between your desktop Feature Phone and your Cordless Handset.
