A method comprises generating an advanced signaling call flow and monitoring one or more finite states for one or more calls using the advanced signaling call flow. The method further comprises determining that there is a failure in one of the one or more monitored finite states for a particular call, and comparing one or more performance indicators to one or more respective thresholds, the one or more performance indicators associated with a cell in which the particular call took place and comprising information about the cell at the time of the failure. The method further comprises flagging one or more of the one or more performance indicators that do not satisfy their respective threshold, and determining a root cause of the failure based at least in part on one or more of the one or more flagged performance indicators and the advanced signaling call flow.
