ESI Cellular Management lets you manage your cell phone calls along with your normal business calls, all from your desktop phone.

The ESI Bluetooth Headset Interface lets you use any compatible Bluetooth headset with your ESI 48-Key Feature Phone.

When your business grows, your ESI phone system expands with it - and, to help you handle all those extensions more easily, ESI also offers the 60-Key Expansion Console. It connects quickly to the ESI 48-Key Feature Phone and gives you these benefits:
Easy to use - Lets your operators transfer calls to any extension with just a keystroke.
Powerful - Adds 60 more programmable feature keys to the 30 already on an ESI 48-Key Feature Phone, giving the user a total of 90 such keys.

Easy to understand - As does each ESI Feature Phone, uses tri-color LEDs to show the simultaneous status of all extensions programmed into the soft feature keys. In fact, if you manage a large department, you may well want this just for its ability to show you, at a glance, your employees' phone activity. For even more monitoring-at-a-glance, add the optional ESI Presence Management.
Versatile - Combines with an ESI 48-Key Feature Phone for any extension.

Compact footprint - Takes up little valuable workspace, especially since it has a convenient four-position base (to match the ESI 48-Key Feature Phone's).
