internal, incoming, or unlimited call authorisation.
Automatic redial

See "ringback when busy"
B
Block dial
See also dial preparation. You can dial the phone number first and then correct it as
necessary. Then you lift the handset or press the loudspeaker key.
C
Call diversion during the call phase
CD, Call Deflection. Must be explicitly enabled by the network provider for each ISDN
connection. CD enables an incoming call to be forwarded to any phone number
while it is ringing, without having to answer the call. Because the caller has no affect
on where it is forwarded (for example, to a mobile phone), you will pay the resulting
charges. The caller must only pay the normal telephone charges to the connection
he dialled.
Call forwarding
CF, Call Forwarding. You want to permanently forward all calls to another number.
Call forwarding can be used externally via the telephone exchange or internally in
the device. Call forwarding can be separately set up for each individual phone
number (MSN) (on holiday on the mobile phone, in the office, to the neighbours,
etc.).
It is done in the local telephone exchange of the network provider. The call does not
reach the original number.
There are three types of call forwarding: immediate (CFU, Call Forwarding
Unconditional), when busy (CFB, Call Forwarding Busy) and with no reply (CFNR,
Call Forwarding No Reply).
