02/13/2026, 9:57 AM@AI Evy I have ~1,000 leads and want to complete all calls in one day without purchasing extra concurrency or enabling burst mode.
If my concurrency limit is 20, does Retell automatically queue batch calls and start a new call whenever one ends (keeping max 20 active calls at a time) until all leads are completed?
Please confirm whether batch calling follows this behavior and if there are any additional costs beyond normal per-minute charges.

Yes, Batch Calling queues your calls without hitting concurrency limits, ensuring a seamless experience. [(1) ]()
This means Retell will automatically manage the queue—starting new calls as others complete—while staying within your 20 concurrent call limit until all 1,000 leads are processed.
Additional Costs:
Beyond normal per-minute charges, Batch Calling has a pricing of $0.005 per dial (20,000 calls for $100) .
So for your ~1,000 leads, the batch dialing fee would be approximately $5 on top of your standard per-minute call costs.
