Outbound Call to US Numbers Not Working (other numbers work)

We are trying to understand the following error: An error occurred in this call: call.start.error-get-transport which only seems to occur when calling out to US numbers. This is using Twillio provider and there are no logs on their end for this seemingly.

Sample Call ID: 019abf62-8bf8-711c-aa30-365ab1305709
