Call Forwarding-Intercept / Announcement
General Description
This feature provides for interception of STATION-TO-STATION [S-11], DIRECT INWARD DIALING [D-8],
Attendant-to-Station and CCSA [C-14] calls that cannot be completed (unassigned station, level, etc.). These calls
are automatically routed to a recorded announcement informing the caller that an inoperative number was reached
and giving the Listed Directory Number for information.
This feature permits a station-originated call, upon encountering a restricted outgoing number, to automatically be
routed to a recorded announcement informing the caller that the dialed number is restricted for this station.
This feature permits a station-originated call, upon encountering a trunk busy condition, to automatically be routed
to a recorded announcement informing the caller that all the outgoing trunks are busy.
Operating Procedure
No manual operation is required, once this feature has been programmed in system data.
Service Conditions
1.
CALL FORWARDING-INTERCEPT / ANNOUNCEMENT requires one of the following hardware
alternatives:
a.) Central Office Trunk (COT) or 2W E&M trunk and an announcement machine, or
b.) Digital Announcement Trunk (DAT).
2.
If the outside party or Attendant forgets to hang up, the system will automatically disconnect in 30 seconds
(provided this is programmed in system data). If no disconnect timing is programmed, the outside party
will control disconnect.
3.
This feature is provided on a per-tenant basis.
4.
The following call conditions, which cannot be completed, can be routed to intercept:
a.) vacant level
b.) unassigned telephone number
5.
Only one common message can be provided for the different intercept conditions.
6.
There is no method by which to exempt individual DID, CCSA, and TIE Trunks from intercept.
7.
A station dials the LEAST COST ROUTING [L-5] access code and then an outside number. If that outside
number is not listed in LEAST COST ROUTING [L-5] tables (Outgoing Routing Patterns, OPR), the call
will be routed to an intercept announcement.
8.
If a different message is required for each of the three intercept conditions, three trunks or three
announcement machines must be provided.
When encountering a Restricted Route
9.
This service feature is valid when station to outgoing trunk connection is restricted.
10.
This feature is applied equally to all trunk routes in the system. It cannot be denied to some routes and
available to other routes.
11.
This service is valid when a call is redirected to an OG trunk via CALL FORWARDING-OUTSIDE
[C-28]. The announcement will be heard when the calling station is also a restricted station.
12.
This service is not valid for TRUNK-TO-TRUNK CONNECTION [T-10] when the called station has set
CALL FORWARDING - OUTSIDE [C-28] via DID or TIE Trunk.
13.
This service is not valid for outgoing calls that do not go out when all trunks or senders are busy.
