Hello! I'm here to help you with your synchronization issue. To assist you effectively, I'll need a bit more information. Could you please confirm if you have already added the provider key for Cartesia in your VAPI configuration? Additionally, ensure that the voice ID you are using matches the one provided by Cartesia for your private voice.
If you've already done this and are still facing issues, there might be a need to look into the specific error messages you're receiving. Could you please share those details? This will help us understand the problem better and provide you with a more accurate solution.
