Telephoning 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. A setting in your user group regulates which call number appears on your device when a call which has been forwarded multiple times is signalled on your device: you will see either the call number of the last user who programmed the last call forwarding in the chain, or the call number of the first user in the chain. The number displayed is also saved to the caller list for missed calls. 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. A loop is also detected during call deflection. If you receive a call via a call forwarding chain and wish to deflect it to a destination call number which is already in the call forwarding chain, a negative acknowledgement tone is heard and the call signalling on your device will continue. 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. 79

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.
A setting in your user group regulates which call number appears on your device
when a call which has been forwarded multiple times is signalled on your device: you
will see either the call number of the last user who programmed the last call for-
warding in the chain, or the call number of the first user in the chain. The number dis-
played is also saved to the caller list for missed calls.
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.
A loop is also detected during call deflection. If you receive a call via a call forwarding
chain and wish to deflect it to a destination call number which is already in the call for-
warding chain, a negative acknowledgement tone is heard and the call signalling on
your device will continue.
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.
