General Functions
52 Telephoning
DTMF Postdial/VF Signalling
Depending on the system’s configuration, your telephone is automatically set
to VF (voice frequency) signalling in the connection state. You can use this, for
example, to query an answering machine or a voice mailbox. Consult your
system administrator if you have questions concerning this function.
Keypad Dialling
A number of European network operators need the keypad protocol to set
features. Depending on your system configuration your telephone could be
set to keypad dialling during the connection state. If this is not the case, you
must switch your telephone over to the keypad protocol – before dialling –
and enter the code digits specified by the network operator. These are
transmitted directly to the exchange and evaluated there. You usually get an
announcement as an acknowledgement. Consult your system administrator if
you have questions concerning this function.
Switching to keypad dialling
Note: In the call state, keypad dialling is automatically active. Once the
called subscriber answers the call, which could be an external
answering machine for example, you can execute the required
functions by pressing the number keys.
For the system administrator
Authorisation for keypad dialling is set in the Configurator , menu User
manager > User groups (setting: Keypad dialling ).
Least Cost Routing (LCR)
Whenever you make an external call, your system automatically uses LCR to
set up a connection to a network operator that has been selected by the
system administrator. If you do not wish to use this preferred connection and
want to select a network operator yourself for each call (i.e. on a call-by-call
basis), then before making the call, select the
LCR off entry from the menu
described in the section entitled MenuCard “Selection” in the Idle State .
