I'm sorry to hear that you're experiencing issues with the voicemail detection. It's possible that there could be an issue on either VAPI's side or Twilio's side. Since you mentioned that there were no changes pushed to your VAPI environment, it might be a problem with Twilio's service or an unexpected interaction between the two services.
To troubleshoot this issue, I recommend checking the following:
1. Review any recent updates or incidents reported by Twilio that might affect their voicemail detection service.
2. Verify that your VAPI settings for voicemail detection have not been altered and are still configured correctly.
3. Check your network connectivity to ensure that there are no issues that might be causing timeouts.
4. Look at the logs for both VAPI and Twilio to see if there are any error messages or warnings that could provide more insight into the problem.
If after these steps the issue still persists, it would be best to reach out to Twilio's support for further assistance, as they might have more detailed information on their service status or any known issues that could be affecting voicemail detection.
If you need any further assistance or if you would like me to perform any specific checks or actions, please let me know.
