You can use the Cisco Spark app to place calls on a Cisco Spark Room Device when your mobile device is paired to it.
You can start calls either from spaces or from the Calls tab.
If you make a call in a space, all participants in that space are notified on their devices. During the call, any room participant can join by selecting the green Join button.
Spaces: Select a space with either one or more participants, and select the Video Call icon to start a call.
Calls tab: Select an entry from your recents list, or select the Dial Pad icon and search for a contact, or enter a number.
To learn more about calls and meetings on the app, take a look the Calls and Meetings in the Cisco Spark App article.
