@Shal Kamboj Hello and welcome to the VAPI community! I'm glad you're reaching out for assistance. The error you're encountering when trying to call the Australian phone number you've purchased through Twilio and connected to your VAPI inbound call assistant squad or assistant could be due to a variety of reasons. Here are a few steps you can take to troubleshoot the issue: 1. **Check Configuration**: Ensure that the phone number is correctly configured in your Twilio account to forward calls to your VAPI inbound call assistant or squad. 2. **Review Error Logs**: Look into the error logs provided by Twilio and VAPI to get more details about the application error. This can give you insights into what might be going wrong. 3. **Validate Webhook URLs**: Verify that the webhook URLs set up in Twilio for incoming calls are correct and that the server hosting these endpoints is up and running. 4. **Test Network Connectivity**: Sometimes network issues can cause such errors. Make sure that there are no connectivity problems between Twilio and your VAPI application. 5. **Permissions and Restrictions**: Check if there are any country-specific restrictions or permissions that need to be set up in Twilio for Australian numbers. 6. **Contact Support**: If you've gone through these steps and are still facing issues, it might be best to reach out to Twilio's support team for more detailed assistance. If you need further help with your VAPI setup or have any other questions, feel free to ask. We're here to help you succeed with your inbound call assistant project!
