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 systems (or locations) 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.

Network numbering

Esi-Link network numbering provides "transparent," or uniform, dialing across Esi-Link. This means that,
regardless of the location from which a user is dialing, the user can dial a number — i.e., the network number —
that matches the called person's three- or four-digit extension number, and the call will be routed appropriately
through the Esi-Link network. In essence, the location number (i.e., 7xx) doesn't have to be dialed, unlike the
case with earlier implementations of Esi-Link.
remember six- or seven-digit numbers to call co-workers. They can call anyone, at any other Esi-Link remote
location, simply by dialing the person's regular extension number. Network numbering provides seamless four-
digit dialing between Esi-Link locations using a network numbering plan.
Important: Because your Esi-Link network may include ESI systems not running software compatible with network
numbering, the instructions herein (except where otherwise noted) assume the need to dial a Location Key when
performing Esi-Link dialing operations. Your System Administrator (or, perhaps, your Certified ESI Reseller)
will let you know the correct procedure for your ESI Communications Server and your Esi-Link network.

Location Keys

Each location in your Esi-Link network has a location number
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
key programmed for the Chicago office and dial 1 0 4 to reach extension 104 in the Chicago office. The number
of Location Keys you can program on your ESI phone depends on how many programmable feature keys it has.
Programming a Location Key
Note: You may wish to review "Programmable feature keys," page C.2.
1. Hold down the desired programmable feature key for at least two seconds to enter programming mode.
2. Enter the remote location number — such as 7 0 2.
Note: You can also use Location Dex (see page H.8) to select the remote location number.
3. Press the feature key again.

Network numbering works only on ESI Communications Servers running compatible system software. If an Esi - Link call involves any legacy ESI systems
(or ESI Communications Servers running earlier system software), users still must dial a location number prior to dialing a remote number. To confirm
whether your ESI Communications Server currently supports network numbering, consult your System Administrator or your Certified ESI Reseller.

Also, you can program up to 60 Location Keys on a 60-Key Expansion Console (see page A.5).
