Department Group - Call Forward
n Description
Department Group Call Forward allows a user to set call forward for calls routed to a department
group.
The forward can be set for each department group and each department group can have its own des-
tination number that the calls are forwarded to. The destination can be either an internal extension/
pilot number or an off premise number.
The feature will operate for calls via ISDN trunk ports that are set as DDI (Type 3 in Program
22-02-01) and internal calls to the pilot number.
The call forward is controlled by service codes and function keys. The destination can also be changed
by the user for each night mode (1-8).
When call forward is set all incoming calls to the department group will be forwarded immediately or
after a delay. Call forward after a delay can only be set via function key 59 and will only operate for
incoming DDI calls to the department group. The delay time is set by Program 24-02-08.
The destination of the call forward is saved in an Abbreviated Dial bin, the bin is defined by Program
24-05-01. If a different call forward destination is required for each night mode then a different
Abbreviated Dial bin must be defined for each night mode. To route the call off premise you must
enter a trunk access digit (e.g. 9) before the destination number. If there is no trunk access digit the call
will route internally. The internal number can be an extension or another department group pilot
number.
It is also possible to chain the call forwards, for example if department group 01 is forwarded to
department group 02 and group 02 is also forwarded extension 250 then calls to department group 01
will ring at extension 250.
A call that is forwarded off premise will be disconnected after timers 25-07-07 & 08.
The outgoing trunk route is defined by Program 21-03-01. A free trunk within this route will be used
when a call is forwarded off premise.
Conditions
Analogue trunks must have disconnect clear enabled when call forward off premise is set, this is to
ensure the lines are cleared when a call is disconnected.
The call forward destination cannot be set from an analogue SLT via Service Code 704.
Default Setting
The service code to enable department group forwarding is 702.
The service code to disable department group forwarding is 703.
The service code to set/change the destination number is 704.
Abbreviated Dial bin 1999 is used as the call forward destination for all night modes.
The disconnect timers are set to give a warning tone after 30 seconds and then disconnect after another
15 seconds.
The outgoing trunk route is not defined.
Disconnect clear is not set.
Trunk to trunk call forward setting is enabled in Class of Service.
