### Answer The message "currently only available with our default credentials" typically means that to test the Eleven Turbo v2.5, you must use the pre-configured API credentials provided by the platform instead of using custom API keys or credentials. This is often done to regulate access to new or experimental features to ensure stability and monitor usage. Unfortunately, specific details on how to proceed with testing or the setup for Eleven Turbo v2.5 using Vapi's default credentials aren't covered in the resources I have. For more specific guidance, you might need to refer to the official documentation provided by Eleven Labs or contact their support directly. If you have further questions about integrating custom voices or other features into Vapi, I'm here to assist!

Got it. Tagging @User for additional help.

Finaly i find how to select v2.5 .. I couldn't select it because I was using an 11labs voice with an ID because it's a French voice. So I unchecked the voice I had ... but I can only use the voices that are on the list but there is no French voice ... 😦
