302 Cors error failed to fetch streaming voice call recordings

Hi Support team, hope your are all doing great, we are using the following documentation to stream recorded audios in our platform Playvox:

We are having problems making the request with a 302 cors response. We researched the documentation with not sucess results.

What would be the standard or supported form to stream recorded audios?
Is there any limitation due we are using a trial/beta account?
