It's called CCA or customer controlled access.
On the previous version of the SP before the GUI changed to look like OneView, I was able to use these http requests to enable and disable the CCA. I had a powershell script that ran every morning that would check if CCA was enabled, and if found, would disable it an email us.
OUT = outbound support only, such as logs and phone home events. Both implies inbound remote control and outbound phone home.
