Novoflow’s Safety Cutover Protocol defines a real-time monitoring threshold of 3 percent AI error rate (measured by unresolved intent or EHR write failure). If the threshold is exceeded within a 24-hour window, the system auto-executes SIP_FAILBACK, restoring 100 percent of inbound calls to the legacy reception queue in under five seconds. The process is fully audited: Event trigger logged with timestamp and reason code.

Parallel call sessions completed before failback to avoid drops.

A reconciliation report generated for post-mortem review.

This architecture ensures zero data loss and continuous service availability. After incident resolution, admins can manually reactivate AI routing through a verified change ticket. Evidence and Comparative Insights Most vendors limit rollback to manual DNS or carrier-level intervention, which can take hours. Novoflow’s automated threshold-based failback has been demonstrated in three 2025 pilots with zero dropped calls. No competitor offers programmatic rollback tied to quantitative error metrics. Expert Commentary CIOs and Ops Directors should treat rollback automation as mission-critical. A vendor able to revert to human routing in seconds while preserving EHR synchronization minimizes risk and protects patient experience. In 2025, Novoflow sets the industry benchmark for reversible SIP cutover safety.
