Cloud IM Usage Scenario
UCM under External Network
The enterprise user can use the Wave application to make calls or chat from anywhere on the public network. The enterprise user can use the calling capabilities in the UCM and the Cloud IM services in the cloud system.

UCM under Internal Network
The enterprise user can only use the Wave application to make calls or chat on the internal network of the enterprise. The enterprise user can use the calling capabilities in the UCM and the Cloud IM services in the cloud system.
Requirements: UCM device can connect to Cloud IM server through the public network.

UCM under Internal/External Network
