The 48-Key Feature Phone has a variety of programmable and built-in features. It comes in multiple versions:
Digital, and three types of IP Feature Phones:
- IP Feature Phone II — Can be installed either “locally” — i.e., on the same local area
network (LAN) as the IP-capable ESI system — or remotely, in which case it accesses the system over the Internet or a WAN.
This version is for use with only ESI Communications Servers.
- [Local] IP Feature Phone — Installed on the same LAN as the IP-capable IVX X-Class or IVX E-Class system.
- Remote IP Feature Phone — Installed remotely, accessing the IP-capable IVX X-Class or IVX E-Class system
over the Internet or a WAN.
The following table shows which ESI systems are compatible with specific 48-Key Feature Phone models:

Each 48-Key Feature Phone supports up to two optional 60-Key Expansion Consoles. All versions
of the 48-Key Feature Phone offer the same basic features which are described throughout this User’s Guide.
The 48-Key Feature Phone’s built-in voice mail features and voice prompts make it easy to program and use.
On any of these ESI phone varieties (including the Expansion Consoles), you can perform
direct programming by holding down a programmable feature key for at least two seconds (similar to how
you might program a car radio button). This isn’t applicable to the fixed-feature keys which, as their
name implies, are already programmed.
Optional Expansion Consoles
for use with the 48-Key Feature Phone
[Not for use with ESI C-Plus or IVX C-Class systems]
Of the systems covered in this on-line User’s Guide, the Second Expansion Console
works with only ESI Communications Servers and IVX X-Class.
Your ESI 48-Key Feature Phone can support up to two optional Expansion Consoles, for a possible total
of 120 additional programmable feature keys.
The 60-Key Expansion Console connects directly to the phone, while the Second Expansion Console
connects to the first Console.
You program each Expansion Console’s keys just as you do the programmable feature keys on your
ESI Feature Phone, using either direct or traditional programming.
Only one key can exist per extension, feature, or operation. If you program a second
key for the same extension, feature, or operation, this automatically erases the first key so programmed, thus
making it available for another extension, feature, or operation.
You may find it easier to write in the names on the overlay before you program the
keys and attach the overlay to the Console.
On any of these ESI phone varieties (including the Expansion Consoles), you can perform
direct programming by holding down a programmable feature key for at least two seconds (similar to how
you might program a car radio button). This isn’t applicable to the fixed-feature keys which, as their
name implies, are already programmed.
