48-Key Feature Phone (legacy product)
The legacy 48-Key Feature Phone, still in use on many installed ESI systems, has a variety of programmable and
built-in features. It has two versions: 48-Key Digital Feature Phone and 48-Key IP Feature Phone II. Additionally, it
supports up to two optional Expansion Consoles (see page A.5). 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.

Hint: 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.
