Advanced digital and IP communications servers
ESI Communications Servers represent an innovative approach to digital and IP communications. The science behind
the switch is sophisticated in its simplicity: Design a platform with the flexibility to support digital functionality with the
ability to be configured as a purely IP-based communications system. It’s ideal for any business that wants the familiarity
of digital telephony, the benefits of full IP-to-the-desktop, or anything in-between.
Introduction
ESI Communications Servers come in several models, to handle
everything from the modest call-handling needs of a small business
to the large, customized needs of the enterprise. Each ESI
Communications Server is fully flexible. That means it can support
traditional digital stations, IP-based, or any combination thereof that
the customer requires.
1
The largest model, the ESI-1000, supports a
maximum system capacity of 1,128 communications ports.
An ESI Communications Server’s backplane
2
, switching matrix, and
main board are designed to allow for a traditional digital installation
or a VoIP configuration in varying capacities. The non-blocking
architecture increases station capacity to a full complement of up to
816 telephones.
3
ESI Communications Servers share many common functions and
features. Their innovative architecture integrates advanced IP
functionalities, such as dedicated IP resources, the ability to support
multiple Integrated VoIP Cards (IVCs), up to 96 Esi-Link channels,
and remotely installed IP Feature Phones.
All ESI Feature Phone models, both digital and IP-based, provide
advanced ESI features. ESI Cordless Handsets come in two sizes,
each of which has three models to provide more connection choices
— Digital, Local IP, and Remote IP. The 48-Key IP Feature Phone II
supports Power over Ethernet (PoE). The optional VIP Softphone
combines the functionality of a 48-Key IP Feature Phone II and the
VIP Professional product in one PC-based phone.
4
All ESI IP
Phones are standards-compliant and operate with the customer’s
local area network to promote Quality of Service (QoS). The 48-Key
and 24-Key Feature Phones are available with backlit displays.
An ESI Communications Server provides an ideal, cost-effective
upgrade path for several models of ESI’s IVX systems.

To support certain ESI Communications Server features — most notably automatic call distribution (ACD) and any IP-related features — the entry-level
ESI-50L must be upgraded to an ESI-50. As a result, a number of descriptions in this document do not apply to the ESI-50L. For a complete comparison
of ESI systems’ features, consult the Technical and Features Comparison Chart (ESI # 0450-0447), downloadable from www.esiresellers.com/tech
