Deleting Callback On Busy; Initiating Reservation Of Exchange Line On Busy - Auerswald COMpact 4000 Operation Manual

If you pick up the receiver, the subscriber will be called.
Note: You also have the option of letting the central office call you as soon as
one of the B channels on the previously called ISDN connection is available.
If the subscriber for which you have set up the callback is telephoning on the
other B channel, this callback will remain unsuccessful.
The control command (keypad) to execute the function, as defined in the
PBX, may differ from the requirements of the network provider. In case of
malfunctions, ask your network provider for the required control command
(keypad) and change the setting (see chapter Settings > Analogue
Connection > Configuring Control Commands). If you want to use the feature
directly on the exchange line instead, the subscriber needs the authorisation
for configuring features to be configured by the network provider.
