Yes, you can manage number access in VAPI by implementing blocklists or custom logic in your call flows. I can help set this up so unwanted numbers are automatically filtered. Regarding models, Azure OpenAI and OpenAI models are functionally similar, but Azure versions are hosted and managed through your Azure subscription with enterprise controls, while OpenAI models are accessed directly via OpenAI’s API. Curious—are you looking to block numbers at the API level or within specific call flows? @kingbuddy.eth
