Using Esi-Link

Important: You are being assigned a special feature not covered in the regular station user guide or
tutorial. Be sure to consult the System Administrator for the Location Numbers used by your
Esi-Link network.

Overview

Esi-Link is an optional feature that networks multiple ESI telephone systems (or locations) and IP Gateways
(see page H.9) across an IP-based network. With Esi-Link, a multi-site business can integrate up to 100 of
its locations, using the latest VoIP (voice over IP) technologies. Inter-office calls, transferring outside calls,
moving voice messages and even accessing outside lines at remote locations are all features you can use
over Esi-Link.
For example: if you have an office in Dallas and another in Chicago, Esi-Link makes it possible for
someone in the Dallas office to dial an extension in the Chicago office just as easily as if it were an
extension down the hall in the Dallas office.

Location Keys

Each location in your Esi-Link network has a location number
dialing into a remote location, you can assign the location number to a programmable feature key —
making it a Location Key. When you press a Location Key, you'll hear dial tone; you can then dial any
extension, department, mailbox, or outside line group access code
a user in the Dallas office would press the key programmed for the Chicago office and dial 1 0 4 to
reach extension 104 in the Chicago office. You can program up to 12 Location Keys on each 24-Key
Feature Phone and up to 30 Location Keys on each 48-Key Feature Phone.
