Error Handling

Examples

Isolate a voice-call failure without changing production routing

Reproduce the reported failure with a test number and a non-production agent version. Capture the call identifier, selected agent version, webhook response code, and timestamp; redact caller audio and personal data from the ticket. Compare that evidence with one successful test call before changing prompts, transfers, or routing. Promote the smallest verified correction through the preview path, then retain the before/after identifiers for rollback.
