Hi team, I’m building a voice workflow using Vapi for a medical triage assistant, where the virtual agent collects patient information (name, DOB, insurance, symptoms, etc.) before transferring to a live agent. In real-world tests, calls are often going beyond the current 10-minute limit, especially when patients need more time to provide accurate information or when secondary insurance and PCP details are involved. Can you please advise if the maximum call duration can be increased to 30 minutes (or more) for workflows under the Agency plan? Appreciate your help—this is crucial for production deployment in the healthcare space. Let me know what’s possible! Thanks, Darpan

Yes, set the maxDurationSeconds parameter in your assistant or API config, just make sure to republish and check for other limits like silenceTimeoutSeconds or SIP provider cutoffs that might still end the call early..

I am using Vapi Number, and it's regarding WORKFLOW not Assistant.

Set "maxDurationSeconds": 1800 in the Start Call node, add patient lookup, triage, and scheduling tools, and connect the workflow to your Vapi Number for 30 mins automated triage calls..

I’m unable to find a maxDurationSeconds setting in the Start Call node GUI — it doesn’t appear as an option. Also, there’s no visible configuration in the Vapi phone number settings UI to set or extend the maximum call duration to 30 minutes. Could you please clarify where exactly this should be set

Hey, I can help with that. The maximum call duration setting can typically be found in the advanced settings of your Vapi phone number configuration. If you're not seeing it there, it might be worth checking if there are any updates or if your account has specific limitations. Let me know if you need more help with this.

I have the same issue, what limits might their be on my account that mean that the maximum call duration is not appearing?
