Hello, I just ran two outbound campaigns and both stopped after 10 calls with status 'completed'. When creating the campaign - and that was the behaviour over the last weeks - it was promised to queue the calls according to the pricing plan (see screenshot). I check the campaign via API retrospectively, and there were all 50 calls uploaded correctly. However, only 10 were executed. Two example campaign ids: - acc70b14-493f-4343-b633-ff17a8408ad1 - 81e768a6-e145-4cc1-b1db-7e9439f29956 Has VAPI a temporary issue, or what is the reason for the unexpected campaign stop? https://cdn.discordapp.com/attachments/1413135208332525600/1413135208848429158/Screenshot_2025-09-04_140849.jpg?ex=68bad438&is=68b982b8&hm=0aba062495a1e2eef5a5eea82fa0cf5891b40d718723672ab9eebabdcdd6758d& https://cdn.discordapp.com/attachments/1413135208332525600/1413135209574170684/Screenshot_2025-09-04_140929.jpg?ex=68bad438&is=68b982b8&hm=7848e308396f683d17db7bfae28931f80c63bdce022b79aa4e00a729b31d2851&

It looks like your campaigns stopped after 10 calls due to reaching your organization's concurrency limit. To allow more simultaneous calls, you can increase your concurrency limit by visiting the [Vapi billing page](https://dashboard.vapi.ai/org/billing) and selecting the appropriate add-on. Action: - Go to your billing dashboard and adjust the "Maximum Concurrent Calls" setting to match your campaign needs. This should enable future campaigns to process more calls in parallel as per your plan. Source: - [Changelog October 10, 2024](https://docs.vapi.ai/changelog/2024/10/10)

Hi Oliver, If your outbound campaign finished after only 10 calls, it's likely related to your concurrency limit. This limit dictates the number of calls Vapi can process simultaneously. By default, the limit could be set to 10, meaning any additional calls would be queued until slots become available. To address this, you can request an increase in your Vapi organization's concurrency limit, allowing more calls to run concurrently. More details on managing these limits can be found in the [concurrency section of the Outbound Campaigns documentation](https://docs.vapi.ai/outbound-campaigns/overview). Also, ensure that your telephony provider's limitations align with these adjustments.

Having the same issue here, stops at 10 calls even though there are 700 entries in the file

Could you also please provide a screenshot of the campaign and the list of calls that did not execute? It seems unlikely that some of the 690 calls did not even attempt to retry unless there were some calls stuck in the queue that never initiated then just stopped trying

Hi Kyle, thanks joining the discussion. I attach three screenshots, do they help you? Or do you need me to share it differently? Screenshots are concering campaign 94c94540-fe7e-49ae-a168-95cabe20e919. I collapsed the list of customer contacts for data privacy and it wouldn't fit on a screenshot anyway. But you see it expands across line 7 to 5508 of the json. https://cdn.discordapp.com/attachments/1413135208332525600/1414863109683806309/Postman_2.jpg?ex=68c11d74&is=68bfcbf4&hm=fa735408e1db20d5bcde07f4e890008deeac610d063a600eb0dfbe18765b7a4c& https://cdn.discordapp.com/attachments/1413135208332525600/1414863110186991676/Postman_1.jpg?ex=68c11d74&is=68bfcbf4&hm=84d556dee907ec204e2d99fb0cd130195ad8e3ae1cd7397c28db181f5e18603d& https://cdn.discordapp.com/attachments/1413135208332525600/1414863110845497344/Campaign_UI.jpg?ex=68c11d74&is=68bfcbf4&hm=95e93b9edbe8d09f48bc2c00d54de59563cb0fb01887f02a766081251fa6605a&
