2.3 Information Mailbox Function

A class 1 mailbox can be configured by the system administrator as an information mailbox that is used solely for long announcements (e.g. a movie program). The announcement can have a duration of up to 20 minutes in this case. Message recording is independent of this feature. The message recording function should be deactivated for purely informative announcement services. The caller can control the playback of the announcement via the number keys on the telephone (fast-forward, rewind, pause, repeat).  

The caller can thus control the playback of long duration announcements (on touch-tone telephones only):
