Retrieve routing instructions and call metadata after a Regal AI voice agent leaves a live call. The response carries the routing decision (route.type of skill, external, agent or hangup, plus route.value and route.reason), static meta.* fields from the integration and transfer-destination configuration, task.* attributes including the task SID, and definedContactData.* values collected by Set Contact Data actions in the Agent Builder. Regal documents this endpoint as currently enabled only for inbound calls connected through the Five9 AI Agent Connect integration, at 10 requests per second.
