[Freeswitch-users] Early Media troubles

[Anthony Minessale]

ringback has nothing to do with playback, it's only relevant to bridge.
trying to call playback before you answer will implicitly create a pre_answer

Do this in your dialplan:

playback file1
sleep 10000
answer
playback file2

if you expect the playback to loop endlessly it would take more steps,
the easiest of which would be to make a 10 second audio file and use:

playback file1
answer
playback file2
