You can use DND to reject incoming calls automatically on the phone. The prompt
message "n New Missed Call(s)" ("n" indicates the number of missed calls) will appear
on the LCD screen, and callers will receive a busy message. All calls you receive while
DND is enabled are logged to your missed calls list.
Note
You can enable/disable DND for the phone system, or you can customize DND for each
or all accounts. Two DND modes:
 Phone (default): DND is effective for the phone system.
 Custom: DND can be configured for each or all accounts.
You can receive incoming calls from authorized numbers when DND is enabled.
To configure the DND mode via web user interface:
1. Click on Features->Forward & DND.
The prompt message will display only if Missed Call Log for the line is enabled. Missed
call log is configurable via web user interface at the path Account->Basic->Missed Call
Log.
Do not disturb is local to the phone, and may be overridden by the server settings. For
more information, contact your system administrator.
