Methodology
Production metrics are sampled from CallSphere's 6 live verticals (Healthcare, Real Estate, Salon, Sales/BDR, Helpdesk, After-Hours Escalation) over rolling 30 to 90-day windows during Q1 and Q2 2026. Industry comparisons use the most recent published data from Smith.ai, traditional outsourced answering services, ICMI, and CCW benchmarks. Latency figures are measured end-to-end including the carrier media-stream round-trip. CSAT is a voluntary post-call survey with a 23% response rate (n = 8,200).
