[Freeswitch-users] schedule Broadcast into a conference

Hi, I am wondering if there is an API command that will allow me to schedule a broadcast into a conference? I have tried the following: sched_broadcast 5 UUID playback::tmp/test.wav I have tried replacing the UUID with the conference UUID and no file plays (though the broadcast shows as being scheduled). I have also tried replacing UUID with one of the caller's UUID, the file does play but only to that one caller and not all callers. many thanks Matt
