### Answer Yes, Retell's batch calling is designed to work within your concurrency limit and automatically manages the call queue for you. [(1) ]() How it works: - The Batch Dialer ensures smooth operation without hitting concurrency limits. - With a concurrency limit of 20, you can have up to 20 simultaneous active voice calls at any given moment. [(2) ]() - Each agent is capable of handling an unlimited number of calls, provided the total concurrency remains within your designated quota. Regarding costs: - Batch calling costs $0.005 per dial. [(1) ]() - For 1,000 leads, that would be approximately $5 in dial costs, plus your normal per-minute charges for connected calls. Additional parameter you may find useful: When creating a batch call, you can use

reserved_concurrency

to reserve a number of concurrent slots for other calls (like inbound calls) that are not triggered by the batch. [(3) ]() Time estimate: The batch call interface shows an estimated time to complete all calls at the bottom of the form when you set it up. [(1) ]() So to directly answer your question: yes, Retell handles the queuing automatically within your batch call, starting new calls as others complete while staying within your 20-call concurrency limit.
