04/24/2025, 10:34 AM# Upgrade to Vapi Enterprise Plan for 2000 Concurrent Calls
The 429 Error occurs because you've exceeded Vapi's default concurrency limit (10 simultaneous calls). To handle 2000 concurrent calls, you'll need to:
Upgrade to the Enterprise plan which offers:
- Unlimited concurrency
- Reserved capacity on dedicated Enterprise cluster
- Ability to scale to millions of calls
Contact Vapi support at support@vapi.ai to discuss Enterprise plan options and pricing for your specific needs.
