ESI Communication Servers

ESI-1000• ESI-600 • ESI-200 • ESI-100 • ESI-50 • ESI-50L

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.

IVX systems

IVX S-Class • IVX C-Class ( we supply the parts and you install the system )
One of these all-digital, all-in-one phone systems is almost certainly what your office needs.

Esi-Link

Our advanced multi-site solution lets you use your data network to
interconnect numerous ESI phone systems as if they were one big system.

Remote IP Feature Phone

It’s a fully featured office phone that can be installed just about anywhere you can have a broadband connection.
For use with only certain, properly equipped ESI phone systems.

VIP

VIP and VIP Professional • VIP PC Attendant Console • VIP ACD • VIP Softphone

The name VIP means Visually Integrated Phone. It works within Microsoft® Outlook® to help you manage your ESI voice mail and contacts from your PC. VIP Professional adds still more features, such as auto-recording*, text-messaging, and color-coded monitoring of station status.
Be sure also to check out our other VIP Professional-compatible applications: VIP PC Attendant Console, which greatly simplifies managing any busy office’s call traffic; VIP ACD, to maximize your customer service when used with ACD-equipped ESI phone systems; and VIP Softphone, which allows you to connect with your ESI Communications Server from a PC via nearly any broadband connection.

VOIP Telephone Systems

The ESI Communication Server family allows you to select VOIP or digital systems

IP telecommunications capabilities

The ESI Communications Server architecture provides a robust infrastructure for both LAN1-based IP telephony and remote IP applications.

Standards-based design

ESI Communications Servers’ IP capabilities are supported by compliance with major industry standards. ESI employs all applicable standards to ensure that, regardless of location, ESI Communications Server IP users experience the best audio quality.

• User Datagram Protocol (UDP).

• Layer 3 QoS support via DiffServ (Differentiated Services).

• Voice compression methods of G.711 (for locally installed IP stations), G.726 (for remotely installed IP stations and VIP Softphone), and G.729 (for Esi-Link connectivity).

• 802.3 100Base-TX Ethernet interfaces.

• Layer 2 Quality of Service (QoS) support through compliance with 802.1p for voice packet prioritization and 802.1q for VLAN (Layer 2) support.

• 802.3af Power over Ethernet.

• Dynamic Host Configuration Protocol (DHCP) for IP address conservation within a customer’s LAN.

• Session Initiated Protocol (SIP) to support SIP-compliant third-party IP telephones.
