B.84. Playback()

Plays a sound file to the caller.
Playback(filename[,options])
Plays filename (in the directory /var/lib/asterisk/sounds/) to the caller. The filename does not include an extension; Asterisk automatically selects the format with the lowest transcoding cost. Options may be specified.
The option skip causes the message to be skipped if the channel is not in the up state.
Answers the channel before the audio file is played, unless noanswer is specified. Note that not alle channels support playback when 'on hook'.
Returns -1 when the channel is hung up. If the file cannot be found, jumps to priority n+101 if it exists.

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:
