Name
Playback() — Plays the specified audio file to the caller
Synopsis
Playback(filename[&filename2...][,options])
Plays back a given filename to the caller. The filename
should not contain the file extension, as Asterisk will automatically
choose the audio file with the lowest conversion cost. Zero or more
options may also be included. 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 yet been answered). 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 file is played. (Not all the
channels support playing messages while still on-hook.) If j is passed as one of
options and the file does not exist, this
application jumps to priority n+101
(where n is the current priority),
if it exists.
