If the language is not specified, then the language set up for the IVR will be used; if no language is defined for the IVR, then the default one will be used, English (en);
The playback sound can be made in foreground or background, based on the where parameter;
The loop attribute controls for how many times the sound is played;
While the sound is played, the user may be requested to enter a digit; the key pressed is saved in the digitvar variable; if digitvar is not supplied, then the digit is not saved
