DNIS (Dialed Number Identification Service) - is a telephone service that
identifies for the receiver of a call the number that the caller dialed. It's a common
feature of 800 and 900 lines. If you have multiple 800 or 900 numbers to the same
destination, DNIS tells which number was called. DNIS works by passing the touch
tone digits (DTMF or MF digits) to the destination where a special facility can read
and display them or make them available for call center programming.
Do Not Disturb (DND) - when this feature is selected, all incoming calls to the
user’s extension are denied. If the station has system forwarding instructions, the
calls will be automatically redirected to another extension, Attendant, or operator.
