Hello! I'm glad to hear you're interested in using a non-listed provider with VAPI. While all voice providers are supported once you've validated your API through the Dashboard, using a server URL in the voice and transcript object is not a standard method mentioned in our documentation.
However, if you have a specific use case or a provider in mind that requires a server URL, I would recommend reaching out to our support team for more detailed assistance. They can provide you with the most accurate information on whether your desired setup can be supported and guide you through the process if it is possible.
Would you like me to assist you with anything else regarding voice providers or any other features of VAPI?
