The evidence overlap.

Both records have documented values for Product type, Use case, Call direction, Technical setup, Pricing model, Published numeric pricing, Call recording, ElevenLabs TTS, Function / tool calling, Silence handling, Transcripts, Call summary 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.
