Defines which connections are permitted on PABX terminals, e.g., internal only, 

incoming only, or unlimited call authorisation.

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.

See "Callback on busy"

Several attempts to call are made automatically when the line is busy.

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.

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.

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.
