When you are in a room with a Cisco Spark Room Device, your Cisco Spark app automatically pairs with it. Once the connection is established, you can use the app to start calls on the room device. When you turn off the app or leave the room, your app gets unpaired from the room device. Unpairing can take up to two minutes, and during this time you can still see your avatar on the room device screen.
The room device shows up on the top of the space list.
You can see your Cisco Spark app avatar on the room device screen.
On a mobile device, you need to turn on Ultrasound Proximity on your app. You can find it under Settings.
Allow recording on your mobile device.
For the connection to work, you can only have one room system that uses ultrasound in a room.
For more information on the calling on the room device with the app, see Make Calls on a article.
