Hey VAPI team, We need to scale to 1000 concurrent users but we're currently seeing that we are lock at 10 (before we were able to adjust this in the UI). How can we manage this? It is very urgent for us. Kind regards, Thomas

Hi Thomas! 👋 I understand you need to urgently scale to 1000 concurrent users but are currently limited to 10. While I can't explain why you were previously able to adjust this directly in the UI, I can definitely help you with several ways to increase your concurrency limits. Here are your options to scale beyond the default 10 concurrent users limit: 1. Purchase additional concurrent lines through the dashboard: - Go to the Vapi Dashboard - Look at the bottom left side of the Dashboard - Click on the green button displaying your organization name - Click on the billing option - On the Billing page, navigate to add-ons where you can purchase additional concurrency limits [Source: Discord thread](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336441893395103820) 2. **Switch to Credit Based Billing**: - Navigate to the [billing page](https://dashboard.vapi.ai/org/billing) - Click "Switch to Credit Based Billing" and make a payment - This allows you to reserve more concurrent calls and scale infinitely [Source: Changelog](https://docs.vapi.ai/changelog/2024/10/10) 3. **Upgrade to an Enterprise plan**: - Enterprise plans include unlimited concurrency and higher rate limits - Fill out the form at [book.vapi.ai](https://book.vapi.ai/) to get started [Source: Enterprise plans documentation](https://docs.vapi.ai/enterprise/plans) 4. **Contact support**: - Reach out to the support team with your specific requirements - They can assist in setting up a solution that scales dynamically with your usage patterns [Source: Discord thread](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1331702240242700440) Given your urgent need to scale to 1000 concurrent users, the Enterprise plan might be your best option, or you could immediately contact support at support@vapi.ai for the fastest assistance.

Thomas, you need to purchase more concurrent lines from the dashboard. There's no alternative to it. So, go to the VAPI dashboard, then to your Billing page. Under the Billing page, click on the add-ons, then you can buy more concurrent lines or purchase more concurrent lines.
