VAPI itself does not automatically add context from previous phone calls to the prompts. However, it is designed to handle assistant requests by hitting your server's endpoint with a message containing the "assistant-request" type and the call object. If your system is designed to save call.customer.number and summary fields to your database for future reference, it might be using this saved information to provide context in subsequent calls.
If you're experiencing issues with assistants citing information from previous calls and you wish to change this behavior, you may need to review and adjust your system's logic for handling and presenting call context. If you need assistance with how to manage or disable this feature, please ask support for more info on this.
