What each is best for
Fonio AI is worth it if… European SMBs and mid-market teams that want a German-founded, GDPR-native AI phone agent without navigating US-first platforms like Vapi or Retell. Solo (€99) fits 1–20 calls/day; Team (€299) opens 5 concurrent lines.
telli is worth it if… outbound sales teams in appointment-heavy verticals (solar, home services, insurance) who want AI voice agents that dial and qualify at scale without hiring more SDRs. Pricing is opaque and quote-driven — expect setup support that varies by tier and per-minute rates that need negotiation.
Bottom line: Choose based on how you want to pay — Fonio AI is hybrid, telli is per usage.
