I have recently acquired 230 concurrent calls, however, when I try to call even 100 concurrent calls or get call statuses by call_id for these calls, I face with 429 error issue.
Need your help here. thanks

Thank you for sharing the details. To help diagnose the 429 error, could you confirm the exact concurrency limit currently set for your Vapi organization (as shown in your Vapi Dashboard under billing or settings)? This will help determine if the issue is due to exceeding your allowed concurrent calls.
