Das Asterisk Buch

Spielt dem Anrufer eine Audiodatei vor.

Playback(Dateiname[,Optionen])

Spielt dem Anrufer die Audiodatei Dateiname (aus dem Verzeichnis /var/lib/asterisk/sounds/) vor. Der Dateiname enthält keine Dateiendung, damit Asterisk automatisch die Audiodatei mit dem niedrigsten Konvertierungsaufwand auswählen kann. Keine, eine oder mehr Optionen können hinzugefügt werden.

Die Option skip bewirkt, dass die Wiedergabe der Nachricht übersprungen wird, wenn sich der Channel nicht im Up-Status befindet.

Normalerweise wird der Channel beantwortet, bevor die Audiodatei wiedergegeben wird, es sei denn, noanswer ist angegeben. (Nicht alle Kanäle unterstützen die Wiedergabe von Nachrichten, wenn sie noch aufgelegt sind.)

Liefert -1 zurück, wenn der Channel aufgelegt wurde. Wenn die Datei nicht existiert, wird zur Priorität n+101 übergegangen, falls diese existiert.

[Synopsis]
Play a file

[Description]
  Playback(filename[&filename2...][|option]):  Plays back given filenames (do not put
extension). Options may also be included following a pipe symbol. The 'skip'
option causes the playback of the message to be skipped if the channel
is not in the 'up' state (i.e. it hasn't been  answered  yet). If 'skip' is
specified, the application will return immediately should the channel not be
off hook.  Otherwise, unless 'noanswer' is specified, the channel will
be answered before the sound is played. Not all channels support playing
messages while still on hook. If 'j' is specified, the application
will jump to priority n+101 if present when a file specified to be played
does not exist.
This application sets the following channel variable upon completion:
 PLAYBACKSTATUS    The status of the playback attempt as a text string, one of
               SUCCESS | FAILED
See Also: Background (application) -- for playing soundfiles that are interruptible
          WaitExten (application) -- wait for digits from caller, optionally play music on hold
