Telephoning
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.
Menu Before and During a Call
When the handset is in the idle or call state, state-dependent menus are displayed
when you press the Menu softkey briefly. Frequently used features are displayed,
which you can then activate.
Examples:
