MUTE/DND key
To disable your handset or speaker microphone during a conversation (either with the handset or
speaker), press MUTE/DND. While the mute function is activated, the MUTE/DND LED will blink rapidly
and the display shows "MUTED."
When your phone is idle and you wish to make sure its calls go straight to voice mail, press MUTE/DND
to toggle your phone in or out of DND (do-not-disturb) mode. The display will show DND and the
MUTE/DND LED will glow amber.
Notes: If you press MUTE/DND while your phone is ringing, this forwards the call to your voice mailbox (see
"Voice mail operation," pp. D.1–D.16) and your station will be placed in DND.
On each Cordless Handset, muting is handled by the side-mounted MUTE button. For DND capability,
assign key code 578 to a programmable feature key (see "Optional features," page F.12).
If your phone system is using ESI Presence Management, your phone's MUTE/DND key won't turn
amber when you exit the building using your electronic key; for more details, refer to the ESI Presence
Management User's Guide (ESI part # 0450-0793). If you're not sure whether your system is using ESI
Presence Management, consult your System Administrator. For more information about ESI Presence
Management, visit www.esi-estech.com/presence.
