Forwarding Calls
Call queue
If a call queue is active for your telephone, this is not taken into consideration
when configuring "Immediately" or "On Busy" call forwarding, and its content
is not transferred to the destination terminal. Calls already in the queue can
only be accepted on the original terminal – after you have deactivated call
forwarding. If you have configured "After Delay" call forwarding, an incoming
call enters a queue if it is active and is forwarded after the delay. As with all
other forwarded calls, you can accept the call on the destination terminal.
SIP terminals
On a SIP terminal you cannot use the code-number procedure described here
to activate/deactivate call forwarding. You can also operate the feature with
the Forum CTI additional programme. To do so, the system administrator has
to authorise you to use this programme. For more information, please refer to
the online help of the Forum 500 / Forum 5000.
Least Cost Routing
Least Cost Routing (LCR) can be evaluated for call forwarding to external
numbers, providing your system administrator has configured LCR and the
LCR application in the Forum 500 / Forum 5000. Ask him about the appli-
cable setting.
Hunt group call numbers
During system configuration, the system administrator can configure call
forwarding destinations for hunt group call numbers. These destinations are
called when all users of a hunt group are busy and/or when a call is not
accepted by any member of the hunt group within a certain time interval.
In addition, the system administrator can determine whether you can forward
incoming calls to the hunt group call number or not. If the system adminis-
trator does not permit call forwarding for your hunt group call number, any
call forwarding that you have programmed on your device is not carried out
upon a hunt group call.
Call forwarding chains
The system administrator can configure the system so multiple call
forwarding instances can be linked one to another to form a chain. A simple
example: user A forwards to user B, who then forwards to user C. A call for
user A is then directly signalled to user C.
The system prevents call forwarding chains from forming a loop, e. g. when
the call forwarding destination refers back to the call forwarding source. When
