General Information Making Calls
Telephone Lock
You can switch the handset tele-
phone lock on or off using the
Protection - Telephone lock menu
after entering your PIN. Switching
on the telephone lock changes dial-
ling rights. You may no longer be
able to make external calls or only
make them to a limited extent.
Blocked/Unblocked Call
Numbers
Your telephone can be blocked from
dialling all or selected external call
numbers. Emergency call numbers
(in Germany 110 and 112) can be en-
tered in a special list, irrespective of
your trunk line access rights, and
thus always be dialled. Consult your
system administrator for details.
Keypad Dialling
A number of European network op-
erators need the keypad protocol in
order to set features (in Germany, for
example, for the “Completion of Call
on No Reply” (CCNR) feature). De-
pending on your system configura-
tion your telephone could be set to
keypad dialling during the connec-
tion state. If this is not the case, you
must switch your telephone over to
the keypad protocol
– before dial-
ling
–
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 sys-
tem administrator if you have ques-
tions concerning this function.
A*12
This switches your telephone over to
the keypad protocol. You can now
enter the code digits for the appro-
priate keypad.
Please note: The setting is deleted
again once the connection is termi-
nated!
Least Cost Routing (LCR)
Whenever you make an external call,
your system automatically uses LCR
to set up a connection to a network
operator (provider) that has been se-
lected by the system administrator.
If you do not wish to use this pre-
ferred connection and want to select
a network operator yourself for a call
(call-by-call), then before making
the call, select LCR off (see the
LCR off menu in the section “Selec-
tion” Menu in the Idle State starting
on page 31). This is only necessary if
LCR has been configured for you in
the OpenCom 100. Consult your sys-
tem administrator about this.
Least Cost Routing (LCR) can be eval-
uated with call forwarding to exter-
nal call numbers, provided your sys-
tem administrator has configured
