Hi, I am getting error unknown for a call which was prematurely ended. I was wondering if you could help me figure out why this would be the case or what caused it. Here is my call Id 45ecd9af-7881-4de7-8083-9043952b69bf

Hey there! 😊 I can definitely help you with that. An "unknown error" for a call that ended prematurely can be caused by several factors. Here are some common reasons: 1. **Network and Provider Issues**: Sometimes, the phone call provider might close the connection unexpectedly due to network problems or maintenance activities. 2. **System and Configuration Problems**: If Vapi doesn't receive a response from Twilio within a certain timeframe after initiating a call, it might mark it as an "unknown error." 3. **Operational Errors**: Misconfigurations in your endpoint settings can also lead to this issue. 4. **API and Software Limitations**: If Twilio fails to identify whether a human or voicemail picked up the call, it can result in irregular session statuses. 5. **Concurrency Limits**: If your system is handling too many calls at once, it might exceed its limits, causing timeouts or errors. 6. **Application Logic Flaws**: Errors in how your application manages call sequences can also lead to this error. To get more specific information about your call, you can check the logs for the call ID you provided. Here’s how you can access the logs: 1. **Log In to the VAPI Dashboard**: Go to the [VAPI Dashboard](https://dashboard.vapi.ai/calls) and log in. 2. **Navigate to the Logs Section**: Look for the "Logs" option on the left side and select "Calls." 3. **Filter and Review Logs**: Use filters to find your specific call ID and check the "Ended Reason" for insights. If you need further assistance, feel free to ask! 😊 Sources: - [Common Causes of "Unknown Error" in VAPI](https://discord.com/channels/1211482211119796234/1211483291191083018/1332286268805087272) - [Troubleshooting Premature Call Endings on VAPI](https://discord.com/channels/1211482211119796234/1211483291191083018/1332133296347549797) - [Accessing Logs for a Specific Call ID in VAPI](https://discord.com/channels/1211482211119796234/1211483291191083018/1334280135683084328)
