"Twilio Connection Failed" ended-reason for Outbou...

Hi all, Some of our production outbound calls are failing intermittently due to an ended reason of "Twilio Connection Failed". It is interesting because most of the calls with the same number + assistant succeed. I raised a ticket a couple weeks ago here (https://discord.com/channels/1211482211119796234/1275602754483785819/1275602754483785819) when we first started observing this issue and it looks like it was auto-resolved before it was addressed. We just started getting another influx of these errors. Here is the behavior we observe: The call log shows an ended reason of "twilio connection failed' The call log in Vapi Call Log table shows no logs, overview, cost, call times, or duration The numbers were not disconnected -- we tested calls to verify the numbers were online Phone number is managed by Vapi Server messages are not sent for the call Most outbound calls are succeeding with the same number, assistant, and in the same prod environment Call Record Examples: 6a3a6f5e-4c45-4b22-a599-760c9f099c5f ee891a8e-9bdb-40dd-8660-bd0f326fd6cc 50c8ae3b-a72f-459f-aa33-ac0cf739bff5 294b02c2-e024-443c-bec4-3bf9128163f9 Any guidance on how to manage + debug these errors would be much appreciated!! Please let me know if any additional dets would help out. Thanks 🙏

@Jeff Hello! I'm sorry to hear that you're experiencing intermittent issues with outbound calls failing due to "Twilio Connection Failed" errors. It's good that you've provided detailed observations and examples of the call records. This information is very helpful for troubleshooting. Since most calls are succeeding with the same setup, it seems like the issue might be sporadic or related to specific conditions that occur during the time of the failed calls. Here are a few steps you can take to manage and debug these errors: 1. **Check Twilio Service Status**: Ensure there are no ongoing issues with Twilio's services by checking their status page. 2. **Review Twilio Logs**: Access detailed logs from Twilio to see if there are any additional error messages or patterns that can provide more insight. 3. **Network and Connectivity Checks**: Verify that there are no network or connectivity issues on your end that could be causing the intermittent failures. 4. **Error Patterns**: Look for patterns in the errors. Are they occurring at specific times of the day, with specific destination numbers, or after certain application updates? 5. **Contact Twilio Support**: Since the issue is with Twilio's connection, reaching out to Twilio support with the call record examples and your observations could yield more specific guidance. 6. **Monitor After Changes**: If any changes are made to your setup or if Twilio provides updates, closely monitor the calls to see if the issue persists. If you need further assistance or if there's anything specific you would like me to do to help you with this issue, please let me know.
