Exceptional Value in a Cost-Effective IP Phone

Z 21i
The Z 21i is an easy-to-use, cost-effective business IP phone with a graphical backlit display, dedicated line keys, and Power over Ethernet (PoE) support.

A dedicated headset port and Electronic Hook Switch (EHS) support offer enhanced usability for wired and wireless headset users.

The Z 21i is fully compatible with Zultys’ ZAC Unified Communication application, allowing users to manage calls and messages directly from their computers.

Key Features and Benefits

The Z 21i phone has been designed with ease of use as a priority. Dedicated and context-sensitive soft keys for commonly used functions such as Directory, Redial, Mute, Volume, Speakerphone, Headset, and Voicemail ensure the user can concentrate on the call at hand rather than how to drive the phone.

Remarkable Audio
