Note: The following features aren’t available on a 12-Key Feature Phone:
• Certain special keys and features (see “Special keys,” page F.1).
• Esi-Dex.
Additionally: to use voice mail, conference calling, and mute/DND on a 12-Key Feature Phone, you must
program these features into programmable feature keys (see “Programmable feature keys,” page C.3, and
“Optional features,” page F.12).
Hint: On any of these ESI phone varieties, 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.

The 12-Key Feature Phone doesn’t have a hands-free microphone, and therefore can’t serve as a true two-way speakerphone.
Its speaker plays pages.
