Modern voice agents expose a set of typed functions (the "tools") that the LLM can decide to call mid-conversation. Common examples: get_available_slots, book_appointment, lookup_customer, transfer_call, send_confirmation_sms. Each call is constrained — the model can only invoke tools you defined, with parameters you specified.
