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.
