Currently when IVR greeting is setup, it does not disconnect caller when they make a wrong selection like press 5 5 5, three times when there is nothing setup for #5. I thought this would be a common feature to prevent caller from constantly pressing the wrong selection and tying up the line. As of now, the only selection that exist is when the greeting plays three times and disconnect, but nothing for when call press wrong selection, leaving them in a non ending loop.
