Playback() — Plays the specified audio file to the caller
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.
