|ControlPlayback( )||Plays a file, with the ability to fast forward and rewind the file|
ControlPlayback( filename [, skipms [, ffchar [, rewchar [, stopchar [, pausechr ]]]]])
Plays back a given filename (without the file extension), while allowing the caller to move forward and backward through the file by pressing ffchar and rewchar . By default, you can use * and # to rewind and fast-forward the playback of the file. If stopchar is specified, the application will stop playback when stopchar is pressed. If the file does not exist, the application jumps to priority n +101, if present (where n is the current priority number).
The skipms option specifies how far forward or backward to jump in the file with each press of ffchar or rewchar .
A pausechr option may also be specified, which will pause playback of the file. Pressing pausechr again will continue the playback of the file.
Returns -1 if the channel was hung up during playback.
