We have done this through API's and Secure Flows for various customers, depending on what they want the experience to be. The hardest part is how to have the voice to be that of the agent without giving them access to prompts. If you are interested in getting a quote for your customer, let me know via Email. It is not something we can do out of the box and there is no real plan to put it in.
