Telephoning
Together with your ISDN connection, your telephone network provider also supplied
you with a range of telephone numbers (so-called multiple subscriber numbers, or
just "MSNs"). You use the Configurator to save and assign these MSNs.
When you have saved your MSNs, you can use them for specific purposes when mak-
ing external calls. The various MSNs are billed separately, which means that you can
book the costs for outgoing calls separately.
