A Do Not Disturb (DND) feature is available to temporarily stop all incoming 

call alerting. Calls can optionally be treated as though the phone is busy while 
DND is enabled. DND can be configured as a per-registration feature. 

Incoming calls received while DND is enabled are logged as missed. For more 
information on forwarding calls while DND is enabled, refer to 

 

on page 

Server-based DND is active if the feature is enabled on both the phone and the 
server and the phone is registered. The server-based DND feature is applicable 
for all registrations on the phone (no per-registration mode) and it disables 
local Call Forward and DND features.
Server-based DND will behave the same as per-SIP2.1 per-registration feature 
with the following exceptions:

• There is no indication on the phone’s user interface whether or not 

server-based DND is active.

• If server-based DND is enabled, but inactive, and the user presses the 

DND key or selects the DND option on the Feature menu, the “Do Not 

Disturb” message does not appear on the user’s phone (incoming call 
alerting will continue).

Configuration changes can performed centrally at the boot server or locally:

Server-based DND is disabled if Shared Call Appearance or Bridged Line 

Appearance is enabled.
