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 SIP-T20P IP phones). The server-side DND feature disables the local DND and call forward settings. If the server-side DND feature is enabled on any of the IP phone’s registrations, the other registrations are not affected. For more information on call forward, refer to Call Forward on page 191.
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.
