Hello, if I purchase the concurrency variables, on the following exemples: 3 concurrencys, 5 concurrencys, 7 concurrencys, 10 concurrencys. What is the amount of calls/day my account is supposed to handle knowing that i have a call queue setted up, apply only for business hours by the way.

Hi zucchi0657, For managing call concurrency with Vapi and Twilio, you'll want to ensure you are within your concurrency limits. Here's how to manage it effectively: 1. **Check Concurrency Limits**: Use the

Subscription.concurrencyLimitIncluded

and

Subscription.concurrencyLimitPurchased

properties to determine your total concurrency limits. More details can be found in our [Subscription schema](https://api.vapi.ai/api/). 2. **Call Queue System**: Implement a call queue system with Twilio to handle excess calls when your concurrency limit is reached. Our [Call queue management with Twilio guide](https://docs.vapi.ai/calls/call-queue-management) provides a comprehensive setup including Twilio queues, concurrency tracking with Redis, and a Node.js server for real-time processing. 3. **Concurrency Tracking**: Keep track of active calls using

concurrencyCounter

as outlined in our [workflow updates](https://docs.vapi.ai/changelog/2025/1/20). 4. **Real-Time Processing**: Utilize event-driven queue processing to immediately handle available capacity and dequeue calls effectively. For detailed implementation, please refer to the [call queue management document](https://docs.vapi.ai/calls/call-queue-management).
