### Answer
Currently, the specific details regarding the timeout settings for function calls or API requests in Vapi aren't explicitly mentioned in the provided documentation. To address the issue of needing more than the standard timeout due to multiple API calls, I recommend optimizing the API call process or handling data retrieval more efficiently if possible.
If adjusting the timeout to 10 seconds is critical for your application's functionality, I suggest contacting Vapi support directly to discuss potential customization of the timeout settings for your specific use case. They might offer solutions or configurations that are not publicly documented.
For now, review your implementation for any possible optimizations and consider asynchronous handling of data retrieval to fit within the existing constraints.
