Reviewing carrier reports, I have ample bandwidth to receive calls however the carrier reports several occurrences of ring no answer. I tried running historical CRA reports but the findings are inconclusive. Any suggestions on how to identify the quantity of calls that are offered and go unanswered by the IVR? Perhaps a CallManager cause code? Should I focus on CTI Route Points or IVR ports or both? I believe the gateways can be ruled out.
