Thank you for sharing the error details. Based on the message "Account not authorized to call +6396291434347," it appears that international calling permissions may not be enabled in your Twilio account, as suggested in the documentation.
Could you confirm if you have already enabled international calling permissions for the specific countries you are trying to reach in your Twilio geo permissions settings?
This will help determine if the issue is due to Twilio restrictions or something else in the Vapi setup.
