incoming only, or unlimited call authorisation.
Authorisation for direct outward dialling
Different users may be assigned different levels of authorisation on a base station.
For example, while User A may only take incoming calls, User B may make calls
without restriction.
Automatic callback
See "Callback on busy"
Automatic redial
Several attempts to call are made automatically when the line is busy.
B
Block dialling
Also pre-dialling. You may only dial or, if required, correct the phone number. Then
you should lift the receiver or press the loudspeaker key.
C
Call diversion (via second B channel / internal call diversion
While external call diversion takes place in the network provider's local telephone
exchange, internal call diversion is implemented by your telephone. Your telephone
diverts the call via the second line of your ISDN connection. This means both phone
lines are engaged for the duration of the call. You pay the charges for the
connection to the forwarding number. However, you save yourself the network
provider's charges for this function.
Call forwarding CF
CF, Call Forwarding. You want to forward calls to another number permanently.
You can divert calls externally via the exchange or internally in the device itself.
