I'm sorry to hear that you're experiencing issues with your Vonage number and VAPI assistant. To assist you better, I'll need a bit more information. Could you please provide me with the error message you're receiving when you attempt to call the Vonage number? Additionally, it would be helpful to know if you've followed all the necessary steps for importing a Vonage number and assigning it to your VAPI assistant as per the documentation.
