Using Zoom Contact Center to contact to a third party AI Agent (Voicebot)

[aklein]

I am looking to contact Zoom Contact Center to a third party AI Agent over SIP/TLS (SRTP). Below is what I am looking for, is there documentation on how to set this up or what is possible? 

1. The Call comes into Zoom Contact Center

2. Zoom Contact Center IVR routes the call to the third party AI Agent using SIP/TLS with UUI/X-headers for metadata

3. Ideally, Zoom Contact Center IVR can retain control over the call, so when the AI Agent "leg" end the call, it can return to the Zoom IVR for further routing (i.e. to a human agent for example).

4. Zoom Contact Center exposes an API end-point  the AI Agent can use, to update the metadata of the interaction so the Zoom IVR can use that metadata to route the call appropriately, i.e. to a specific queue for example.

Note: If the Zoom Contact center IVR cannot retain control over the call when it is passed to the third party AI Agent, can a SIP REFER w/UUI or X-headers be used to transfer the call back to Zoom for human agent handoff?
