We're planning to make outbound calls, but looking at the documentation and Discord messages, I'm not clear on the concurrent call limit. If you could confirm, if a call is made from the "Create Call" API: 1. Can multiple customers be added to the call. Is there a limit on the API call? 2. If more customers are added than the concurrent call limit, will calls that exceed the limit be canceled or remain in queue? How is this actually processed? We would have to manage how many calls are active and create more calls as they are completed and do not exceed the concurrency limit. 3. When a call is made to a customer and the call is not answered, does Vapi retry the call until it is answered? How is this handled by default? I've seen that there is an event that calls the webhook that can be triggered when this happens.

Summary of what is known: - You can add multiple customers to a batch call using the

customers

array in the Create Call API. - Batch calls are processed concurrently, but the documentation does not specify a concurrency limit or what happens if it is exceeded. - There is no documented default retry behavior for unanswered calls. Could you clarify if you have a specific concurrency requirement or expected call volume, so I can help investigate any platform-specific limits or best practices for your use case?
