@andromate12357892 It sounds like there may be an issue with the configuration of your assistant or the way the phone number is set up to interact with it. The error message suggests that the Assistant ID might not be correctly set on the phone number you're trying to call. To resolve this issue, please ensure that the Assistant ID is properly associated with your phone number in your VAPI settings. If you've already checked the webhook URL and it's correct, the next step is to verify that the Assistant ID is correctly set in the configuration for the phone number you're using. If you're certain that all settings are correct and you're still encountering this error, it may be helpful to review the debugging artifacts sent to your server as the error message suggests. These artifacts can provide more detailed information about what went wrong during the call setup. If you need further assistance with reviewing the debugging artifacts or ensuring that your Assistant ID is set up correctly, please let me know, and I can assist you with the next steps. If you have any other questions or need additional support, feel free to ask.
