AI agent estimates use all-in per-minute rates (voice engine + LLM + telephony) or plan bundles with overage. The human baseline assumes a part-time receptionist at $17/hour handling only these call minutes — real staffing costs (idle time, benefits, coverage hours) run higher. Pricing verified: 2026-07-01.
