48-Key Feature Phone
[Not for use with ESI C-Plus or IVX C-Class systems]
The 48-Key Feature Phone has a variety of programmable and built-in features. It comes in two versions: 48-Key Digital Feature Phone and 48-Key IP Feature Phone II.
Important:
If you’re using a 48-Key Feature Phone, please note that this phone has separate PROGRAM and HELP keys, rather than the combo PROG/HELP key found on the other models supported by your ESI system. Therefore, you should press PROGRAM if programming your phone and the instructions tell you to press PROG/HELP; or, similarly, you should press HELP if the instructions tell you to press PROG/HELP to obtain assistance from the Verbal User Guide described herein.
The following table shows which ESI systems are compatible with specific 48-Key Feature Phone models:
| 48-Key Feature Phone model | System compatibility | |||
| IP Server 900 | ESI Communications Servers | |||
| Digital |  |

| IP | |

Each 48-Key Feature Phone supports up to two optional 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.
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.
