An ESI Communications Server is a powerful tool around which you can build your organization’s entire telecommunications strategy. 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.

Regardless of which model you select (they vary primarily by call-handling and voice message storage capacity), an ESI Communications Server will serve your needs now and for years to come. This fully flexible communications platform can support both digital telephony and IP-to-the-desktop in any desired combination. ESI Communications Servers also deliver massive expandability and the greatest functionality ESI has ever offered.

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. Backlit displays are available for the 48-Key and 24-Key Feature Phones; the backlit 48-Key Feature Phone includes adjustable backlighting as well as a full-duplex speakerphone.
