Direct Inward Station Dialing
The direct inward station dialing (DISD) feature allows an external
party to call an intercom station directly without assistance from the at-
tendant if the call is made over a line programmed for that purpose. As
the system attendant, you may instruct callers to make DISD calls when
necessary.
For example, if a caller regularly dials a number that rings at the
attendant’s station for service, you may give the caller the DISD line
number and the extension number associated with the station he is
trying to reach. Future calls from the caller to a specific party will not
have to be serviced at the attendant’s station, although a ring-no answer
or busy condition at the called party’s station will result in the system’s
handling the call in another manner (described below).
When a caller makes a DISD call from an outside line, he or she will in-
itially hear ringing. The system will answer the call with a DISD con-
tinuous dial tone; the caller can then dial an extension number.
-
If
called station is
idle, a tone is sounded and called station rings.
- If the
call is answered by another station user, the
caller can ask for
transfer to desired station.
- If
ringing stops
and dial tone sounds again, the caller can dial another
extension number.
-
If
called station has callforward
feature set, forward station rings.
-
If
calied’station is busy,
call is placed on hold and camped-on at busy
station. If
camp-on is not answered
within a transfer recall timeout
period, busy tone is given, followed by a DISD dial tone.
Note: The system will return the caller to DISD dial tone two additional times
and then drop the line.
-
If
called station is busy but ispartof a huntgroup,
DISD call is routed
to idle station in hunt group, if available; otherwise, the call is camped-
on at dialed station. Hunt group is not followed when caller hears
ringing but receives no answer.
-
If
an invalid extension number
is
dialed,
an error tone is sounded
before DISD dial tone is returned (caller can redial). If
mistake in
dialing is made,
caller can dial +K for new DISD dial tone.
Note: The system will return the caller to DISD dial tonetwo additional times
and then drop the line.
-
If
extension number dialing is not completed within the programmed
dial time limit,
call is routed to DISD assist station if available;
otherwise, the line is dropped.
