If you are referring to a ringback tone when they first dial your
system, meaning that they immediately hear your IVR when they dial your
PBX's number, it's because that's how it's supposed to work. Unless you
tell your PBX to use the Ringing() app and wait for a period of time,
Asterisk normally picks up at the beginning of the IVR (since the first
thing you have to do to send audio via Background or Playback is issue
the command Answer() to start sending actual audio. (Note: The Ringing
app just signals RINGING to the remote party)
