IVR
From Taridium
IVR's or interactive voice response systems are setup under Applications → IVRs - All changes made become effective in realtime, so be careful when changing settings on a production system!
IVR's are sometimes also known as Auto Attendants or Automated Attendants.
Adding IVRs
Adding an IVR requires at least an IVR name (descriptive name) and the selection of a prompt. A prompt is a sound file that is played back when you call into the IVR.
