Explanation

On a Cisco Expressway Core, the dial plan processes calls in the following sequence: (1) Transforms - modify the alias (e.g., URI or dial string) before lookup; (2) CPL (Call Processing Language) - apply call policies based on scripted rules; (3) User Policy - apply policies defined for individual users or groups; (4) Search Rules - determine where to route the call (which zone or neighbor to query). Understanding this order is critical for troubleshooting dial plan issues, as each stage can alter or affect how the call is processed before reaching the next step.
