Early media can be played with no answer by editing sip conf values.

1) Set "prematuremedia" param to 'no' 2) Set "progressinband" param to 'never'

Then giving Progress() command at beginning of dial plan and later a 
Playback(demo-congrats,noanswer) OR Playback(demo-congrats) will play the audio 
on caller side.
