S 4.39 Deactivation of answering machines for periods of absence

Initiation responsibility: IT Security Management

Implementation responsibility: IT-user

To prevent misuse, answering machines can be deactivated or disconnected from the telephone network for periods during which they are not required. This should be ensured particularly for answering machines with a room monitoring function.

It should be noted that, in certain cases, inactive answering machines are activated automatically if the connection is not established after a certain interval (e.g. after 10 rings).
