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 for-
warding chain and wish to deflect it to a destination call number which is already

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 for-
warding chains and eliminate any possible conflicts.
