I'm not sure what you mean by that question, but suspect the answer is yes; I believe all of our portfolio can be used to call all other parts of our portfolio if it's set up correctly.
It depends on what you mean by "Webex on-premise" - if you're referring to the old Cisco Webex Meeting Server, then the answer is likely No.
