The evidence overlap.

Both records have documented values for Product type, Technical setup, Pricing model, Deepgram STT, OpenAI models, Anthropic models, Google models, Bring your model, Function / tool calling, Interruption controls, Transcripts, Official product documentation 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.
