Hello!
I'm sorry to hear you're experiencing issues with calls failing on Twilio. To better assist you, I'll need to gather a bit more information. Could you please provide me with the following details:
1. The timestamp of when the call attempt was made.
2. Any error messages or codes you received.
3. The context of the call, such as whether it was an inbound or outbound call, and what you were trying to achieve.
Once I have this information, I'll be able to investigate further and offer you some guidance on how to resolve the issue.
