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 such that 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 on your device.
The system prevents call forwarding chains from forming a loop, e.g. when the call for-
warding 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.
