Do Not Disturb
Do Not Disturb (DND) allows IP phones to ignore incoming calls. DND feature can be
configured on a phone or a per-line basis depending on the DND mode. Two DND
modes:
 Phone (default): DND feature is effective for the IP phone.
 Custom: DND feature can be configured for each or all accounts.
A user can activate or deactivate DND using the DND key or DND soft key (not
applicable to the SIP-T20P IP phone). DND activated on the IP phone disables the
local call forward settings. The DND configurations on IP phones may be overridden
by the server settings.
The DND on code and DND off code configured on IP phones are used to
activate/deactivate the server-side DND feature. They may vary on different servers.
