Hi there! I see you're experiencing the "vapifault-transport-never-connected" error on multiple calls. This error typically indicates a failure in establishing a telephony connection within Vapi's system. Common causes of this error: 1. Network issues preventing WebSocket connections 2. Telephony provider problems (e.g., Twilio connectivity issues) 3. WebSocket connection failures due to invalid or expired URLs 4. Misconfigured settings in your Vapi setup 5. SIP and network configuration issues Here are some troubleshooting steps you can try: 1. Verify network settings: - Check if your network allows WebSocket connections on required ports - Look for firewall restrictions that might be blocking connections 2. Check telephony provider: - Examine logs from your telephony provider (like Twilio) - Verify the provider is properly connecting to Vapi 3. Test WebSocket connections: - Verify your WebSocket URLs are active and correct - You can test using a tool like `wscat`:
Copy code
wscat -c wss://[your-vapi-url]
4. Review SIP configuration: - Ensure SIP URI is correctly formatted - Verify SIP server can accept calls from Vapi servers - Check codec compatibility between Vapi and your SIP endpoint 5. Examine logs: - Review SIP server logs and Vapi logs for specific error messages - Look for patterns in the connection failures Let me know if you need more specific help with any of these steps! 🔍 Sources: - [Discord Channel](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1342542851795324948) - [Discord Channel](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1329235631855108128) - [Discord Channel](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336713212233515089) - [Discord Channel](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334077307966590986)
