keypad. The caller inputs the appropriate digits or letters. When the system recognizes a match, a
recorded announcement states the name of the dialed party for confirmation by the caller before
automatically completing the call. If the input digits are not uniquely associated with a particular
station, the system may ask the caller to pick a name from a menu of choices. The Telecor VS1
phone system can be programmed for Dial By Name using either the first three letters of a person’s
first name or the first three letters of a person’s last name.
Dialed Number Identification Service (DNIS)—A feature of 800 number lines that provides
the number the caller dialed to reach the attached system. DNIS tells you the number that the caller
dialed. Using DNIS capabilities, one trunk group can be used to serve multiple applications. The
DNIS number can be provided in a number of ways, in-band or out-of-band, ISDN or through a
separate data channel. Generally, a DNIS number is used by the answering system to identify the
reason the caller dialed.
DID—An abbreviation for Direct Inward Dialing. See Direct Inward Dialing.
