Done 🚀. You have successfully enabled the rate-limiting feature for your chatbot.   Voice calls have separate limits In Deployment → Chat Widget → Advanced Voice Settings, set Maximum Call Length from 1 to 10 minutes and configure Daily Calls per Visitor.   The daily limit counts calls from the same browser within any 24 hours, including across new chats. Clearing cookies or using another browser resets identification; it is not a verified per-person limit. Chat Widget previews are excluded from the daily call count but still consume credits.   Voice message credits Voice conversations use 50 message credits per minute, calculated by the second. Voice tests and speaking-style previews use the same rate. A two-minute voice session uses 100 credits.   Manage usage in Deployment → Chat Widget → Advanced Voice Settings using Maximum Call Length and Daily Calls per Visitor.
