I would like to be able to make more than 10 simultaneous calls. Is it possible to increase this number?

Our [Enterprise plan](https://vapi.ai/pricing) includes unlimited concurrency, higher rate limits, and features like hands-on support, a shared Slack channel, HIPAA BAA and SOC 2 certifications, Single Sign-On (SSO) support (Okta, Azure AD, SAML, OIDC), and Role-Based Access Control (RBAC). If this sounds like it could meet your needs, please contact our sales team via this link: . Once submitted, our sales team will reach out after reviewing your requirements!

Yes, you can increase your simultaneous (concurrent) call limit in Vapi. - By default, Vapi allows 10 concurrent calls. - To increase this, you can purchase additional concurrent lines at $10 per line/month. Example: > To add 5 more lines (for a total of 15), your additional cost would be $50/month.

Hi Brennowisk, To manage your Vapi call concurrency more effectively, here are some summarized steps you can take based on your needs: 1. **Default Concurrency**: You have 10 concurrent call slots by default. If you frequently hit this limit during large campaigns or spikes, consider batching your call lists into smaller groups (e.g., 50–100 numbers). 2. **Increase Concurrency**: To handle higher volumes, increase your concurrency limit via the [Vapi Dashboard](https://dashboard.vapi.ai/settings/billing) under Settings → Billing → Reserved Concurrency (Call Lines). 3. **Monitor Usage**: Use the Analytics API to review historical concurrency usage and spot patterns at

/analytics

. 4. **Queue Management**: If your call volume exceeds the concurrency limit, implement a call queue using Twilio to hold excess calls until slots are available. The setup can help prevent call drops and manage overflow effectively. 5. **Consider Upgrading**: If your usage consistently exceeds 50,000 minutes monthly, explore custom or add-on plans that offer higher concurrency or additional call lines as needed. You can find detailed steps and features for each in the [Understanding Call Concurrency](https://docs.vapi.ai/calls/call-concurrency) document.
