The CS-50 architecture allows expansion when required. Each Base cabinet and optional expansion cabinet are wall mountable and require very little space in your phone closet.
System highlights (maximum capacities shown)
An ESI Communications Server is a powerful tool around which you can build your organization’s entire telecommunications strategy — and you don’t have to know it all in advance.
That’s because an ESI Communications Server — the ESI-1000, the ESI-600, the ESI-200, the ESI-100, or the ESI-50 — can be a traditional digital business phone system, a fully standards-based IP telephony system, or any mix of the two. The choice is entirely yours, and the mix can easily change when your needs do.
Its ease of use and feature-richness reduces staff frustrations, increases productivity and enhances your corporate image. And ESI's unique integration provides call processing efficiency and cost savings previously impossible.
ESI CS 50 System Features
Full integration - With an ESI business telephone system, just one compact cabinet does what other systems must combine multiple boxes to do. Grows with your business or organization, with up to:
32 digital stations
12 IP stations
8 fully functional analog ports
Six built-in voice mail ports
60-hour voice storage
Digital Feature Phone
Three versions: 48-Key, 24-Key and 12-Key

Stylish and compact, to fit any workspace.
Convenient four-position tilt mount; also wall-mountable.
Simple installation with one-pair, non-polarity-sensitive wiring.
“Ruggedized” design resists abuse and spills.
Big, easy-to-read display with as many as three high-contrast lines. Provides various combinations of the following, depending upon the system model and configuration, the ESI Feature Phone model and the current operation:
Date and time
Current line usage
Phone number dialed
Name of caller
Elapsed time on current call
Remaining time on currently playing message or recorded call
Dedicated feature keys; Esi-Dex™ (indexed speed-dialing) keys; and up/down keys for independent digital control of speaker and handset volume.
Programmable feature keys provide one-touch access to stations, lines, speed-dialing and other features.
Tri-color LEDs make keys’ use even easier.
Works with not only with ESI-50 but also ESI-100, ESI-200 and ESI-600 systems — simplifying migration when your business needs a bigger system.
High-quality speakerphone (48-Key and 24-Key Feature Phones) gives you hands-free ease for both talking and listening when it’s necessary. ESI's audio is unusually sensitive for any speakerphone, much less for a phone in ESI’s price class.
