The evidence overlap.

Both records have documented values for Product type, Call direction, Technical setup, Human fallback, Cold transfer, Pricing model, Twilio, Call recording, MCP tools, Knowledge base / RAG, Function / tool calling, Interruption controls and additional fields shown in Compare. Matching availability does not measure behavior under your call conditions.

Run the same booking, tool failure and unsuccessful human-transfer cases. Record both outcomes and billable units before signing a deployment agreement.
