Unless you go external to a third party or have developer who can extract the details you want from your operating IVR flows then you are left in the dark as to how your iVR is functioning for your customers.
Inbound Queues and Outbound campaigns have reports associated to them, why not IVR and Call flows?
Help identify how you can improve your IVR experience for your customers, Identify the errors and improvements.
