ESI CS 1000 - Communication Server

The ESI-1000 Server architecture allows expansion when required. Each system cabinet (one Base Cabinet and up to five Expansion Cabinets) mounts in a standard equipment rack or on the wall.

ESI CS 1000 Server is Powerful — but friendly

Despite its long list of features, an ESI Communications Server — thanks to famous ESI ease-of-use — is a phone system you’ll find friendly. It says, “Good morning.” It teaches you how to use and program it. It reminds you to change your personal greeting after a trip. And it stands by, ready to assist you whenever you need help. There are several different models of ESI desktop Feature Phones. Each is a compact, attractive addition to any desk, designed to simplify your telecommunications. Here are just two examples:

The phone display is large and easy to read; that's even more true for a backlit display, which is available on certain models.
The dedicated function keys (so you don’t have to memorize codes) give you more ease of use, even with an ESI Communications Server’s enhanced capabilities.
On the go?

If you’re frequently on the move throughout your workplace, an ESI Cordless Handset II is the easiest way to stay in touch with other system extensions, not to mention your voice mail. The ESI-exclusive Quick Switch feature makes it easy to go from desktop extension to the Cordless Handset II at a moment’s notice; just press a key. Or, if you’re “tied” to your cell phone, ESI Cellular Management — part of ESI Bluetooth Voice Integration — simplifies your communications through the power of fixed/mobile convergence.
