Hi, I have integrated 1 Australian mobile phone number in Vapi from Twillio & selected an assistant for inbound calls. But when we try to call that number it's saying 'We're sorry, an application error has been occurred. Good bye!' And the call is getting disconnected. Can you please tell why it's happening & how can I fix it?

Ensure the correct assistant is selected, verify the Voice URL in Twilio settings, check Vapi and Twilio logs for errors, and test with a different phone number to isolate the issue.

@Subhadip Are you on the Twilio free account or paid account ?

I'm on paid Twilio account

Hmmm... on Twilio, can you see the inbound calls being registered in the logs?

No I can only see the Outbound Api logs in Twilio, no inbound call logs registered.

So, you dial your assigned number - but the call doesn't get registered? did I understand correctly ?

Hey @subhadip, can you share your phone number ID.
