Switching on / off call protection
If you want to prevent the telephone from ringing, it is possible to activate a call
protection. The caller then hears a line busy tone. In case of some ISDN telephones
it is also possible to activate call protection in the menu of the telephone. In this case
the caller hears a tone to indicate free line (may differ depending on manufacturer).
If call protection is switched on:
•
it is still possible to make outgoing calls.
•
the telephone rings nevertheless with activated call completion (--> page 21).
