Hi there! 👋 I see you're having trouble with the Flutter SDK and encountering a DNS resolution error. I'm unable to determine your specific device environment or what other solutions you've tried beyond upgrading the daily flutter package. However, I can definitely help with troubleshooting the main error you're seeing: "IO error: failed to lookup address information: nodename nor servname provided, or not known". Based on the information I found, this error typically occurs due to network connectivity or DNS resolution issues. Here are some troubleshooting steps you can try: ### 1. Check your endpoint URL The error might be caused by using an incorrect endpoint URL. Make sure you're using the correct URL format and not sending requests directly to IP addresses. According to the documentation, direct requests to IP addresses are blocked, and you should send inbound requests to sip.vapi.ai instead:

You cannot send requests directly to our IP addresses. Instead, you must send inbound requests to sip.vapi.ai.

### 2. Verify DNS and network configuration Make sure your DNS settings are correct and that your network can resolve the domain names used by the Flutter SDK: - Verify that your DNS settings are correct - Check that your network allows outbound connections - Ensure there are no firewall or network restrictions blocking the connections ### 3. Check for outdated configuration Some users experienced issues with outdated configuration parameters: - The

serverurl

field is no longer needed in newer versions - Try removing the "provider" property from your request if you're using it ### 4. Verify network connectivity Ensure that: - Your internet connection is stable - Your network allows WebSocket connections - There are no firewalls or proxies blocking the connection ### 5. Check API endpoint availability Confirm that the API endpoint you're trying to reach is available and not experiencing any downtime.

To help track down this issue, could you share one or two: - The call ID - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help us figure out what went wrong!
