figured “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
OpenCTI 50 / Aastra CTI 800 additional programme. To do so, the system adminis-
trator has to authorise you to use this programme. For more information, please refer
to the online help of the OpenCom 100 / Aastra 800.
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 OpenCom 100 / Aastra 800. Ask him about the applicable 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 administrator 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 for-
wards 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 the system
detects a call forwarding loop, no further call forwarding is carried out. This can mean
that – despite call forwarding being programmed – calls are nonetheless signalled
on your device.
Contact your system administrator if call forwarding is not functioning as expected on
your device. The system administrator is able to analyse call forwarding chains and
eliminate any possible conflicts.
