### Answer Since single outbound calls work but batch calling stopped, here are a few things to check: 1. Batch Call Status Check your batch call status in the Batch Call tab. Batch calls can be in different states: Draft, Planned, Ongoing, or Sent. [(1) ]() 2. Time Window Configuration If you configured a Batch Call Window, calls will only go out during the specified hours and days. Verify your time window settings haven't restricted when calls can run. [(2) ]() 3. Concurrency Limits Batch calls queue without hitting concurrency limits, but if

concurrency_limit_reached

appears as a disconnection reason, you may need to add retry logic with exponential backoff or consider an enterprise plan. [(3) ]() 4. Check Call History Metrics In the batch call details, review the metrics (Sent, Picked Up, Successful) and click the history icon to view individual call details and disconnection reasons. [(1) ]() 5. Disconnection Reasons to Look For Common error disconnection reasons include: -

concurrency_limit_reached

– concurrency limit hit -

no_valid_payment

– payment issue (though you mentioned payment is successful) -

error_retell

– unspecified Retell-side problem [(3) ]() Could you check the batch call status and share any disconnection reasons you're seeing on the failed calls? That will help narrow down the issue.

@AI Evy looks like the batch call stuck at ongoing

### Answer A batch call stuck in "Ongoing" status is a known issue that has been reported and resolved by the Retell team before. [(1) ]() [(2) ]() Recommended Steps: 1. Check Retell System Status – Visit the [Retell AI Status Page]() to see if there are any ongoing system issues affecting campaign processing. [(1) ]() 2. Verify Phone Number Setup – Ensure your phone number is active and linked correctly to your agent. 3. Review Campaign Settings – Double-check your schedule, time zone, and contact list configurations. 4. Contact Support with Your Batch IDs – If the issue persists, share your batch call IDs with the Retell support team so they can investigate. In previous cases, there was a task blocking others that required dev intervention to fix. [(1) ]() [(2) ]() Based on past reports, stuck batch calls have sometimes resolved on their own after some time, or required the Retell team to manually address a blocking task. [(2) ]() Could you share your batch call IDs here so support can take a look?
