Forwarding Calls Systematic Telephony
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 procedure described here to activate/deac-
tivate call forwarding. You can also operate the feature with the Telefonie-Assistent 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 Comfort Pro.
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 Comfort Pro. 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 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 the system detects a call forwarding loop, no further call for-
warding is carried out. This can mean that – despite call forwarding being programmed – calls are none-
theless 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.
