Thanks for sharing the error details. The message "Twilio Error: Account not allowed to call +16025405640" suggests your Twilio account may not have outbound calling enabled or is restricted from calling certain numbers.
Could you confirm if outbound calling is enabled for your Twilio account and that your number is verified for outbound calls? This will help narrow down whether the issue is with account permissions or number configuration.
If you need guidance on checking this, let me know!
