asterisk users - Apr 2007 - zaptel/pri, early audio, dial()

Hi,
 
Is it possible to have early audio while waiting for answer in a Dial()?
 
Say that I want to do this:
 
1,Progress()   // Establish early audio possibillites
2,Dial(SIP/user,20,z(repeated-musicfile))
 
Where z would be like a function for playing early audio.
Or z would just start MOH without Answer()'ing first.
