Recorded announcement machines
Recorded announcement machines store prerecorded voice messages
that are played back to the trunk units to which they are connected. Most
commercially available announcement machines store recordings digitally,
although some drum and tape units are still in service.
An announcement machine can provide one or more channels and each
channel may be prerecorded with a different message. Some announcement
machines also provide a Special Information Tone (SIT) capability. These
tones are inserted at the beginning of intercept messages such as "Your call
cannot be completed as dialed. Please check the number and try again."
