Play a sound after user answer call

I need to play a sound after the call is answered, is this possible?

s,1,Playback(all-circuits-busy-now,noanswer) like this if it fails works is there any opposite way?

Hi YOu can play a file to the called party, check out the notes for he Dial application, you will find an option there


I found this option A( x) but i also need to play the sound to the caller

The L option does the trick thanks
