ESI 40 phone
The ESI 40 phone has a variety of programmable and built-in features. The model that works with your system is
the ESI 40D (a digital phone). It supports up to two optional Expansion Consoles (see page A.5). The ESI 40 offers the
same basic features which are described throughout this User’s Guide. The 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.
