Blocked/Unblocked Call Numbers
Your telephone can be blocked for all or for certain external call numbers. Emergency call numbers (110/112
in Germany) can be placed on a special list – no matter what your external authorisation – and can thus be
dialled at any time. Ask your system administrator about it.
Keypad Dialling
Some European network operators require the keypad protocol in order to be able to set features. Depending
on the system configuration, your telephone is automatically set to keypad dialling during a call. If not –
before dialling – you have to switch your device and enter the codes stipulated by the network operator.
These are then directly forwarded to the exchange and evaluated there. You usually receive an
announcement in response. Please contact your system administrator if you have questions regarding this
function.
Now your telephone has been switched to the keypad protocol. Now you can enter the keypad codes.
N
Note: This setting is deleted once again when the call is completed!
Least Cost Routing (LCR)
For every outgoing external connection, the communications system automatically makes a connection – via
LCR – to a network operator defined by the system administrator. If you do not use this preferred connection
and for a single call would like to select a network operator yourself (call by call), switch LCR off before
making the call (please refer to the “LCR off” menu entry in the Menu when Pre-dialling starting on page 63
section).
N
Note: The baby call and external call forwarding are not automatically conducted via
preferred connections. This is where you can prefix the codes of the desired network
operator when entering the call number, when you wish to use a different network
operator than the standard one.
