Making the Switch: Migration Guide
How to transition from human to AI (or implement hybrid)
Start with After-Hours (Low Risk)
Keep your human receptionist for business hours, let Kestrel AI handle evenings, weekends, and holidays. This gives you 24/7 coverage with zero risk to your existing operations.
Add Overflow Coverage (Medium Risk)
Human answers first, but when they're on another call, Kestrel picks up immediately. This eliminates missed calls during busy times without replacing your receptionist.
Full Replacement (High Savings)
Once you're confident in Kestrel's performance (usually 2-4 weeks), transition to AI-first. Your human receptionist can focus on higher-value tasks or you can reduce staffing costs.
