This document explains how to register a Cisco TelePresence or WebEx device to Cisco WebEx Cloud Service Using API or Local Web Interface use. This procedure is applicable for Collaboration Endpoint Software 9.8 and later. In previous versions you had to be in front of the device to activate device to the WebEx Cloud service. The new xCommand allows programmatic / remote WebEx activation. If you have many devices already registered on- premises you can use this API to issue the activation code. The device will switch to WebEx automatically.
