If you are a Super Admin, your call logs and smes received on your mobile would automatically be synced, once you download the app. To track your team’s calls, you’ll have to add users (Note: Added Users should have the mobile app installed on their phones).
Also, the tracking of the calls and smses depends on what settings you choose to sync. To track both the data,
1. go to “Settings”
2. check the "SMS" or "Calls" or both to sync
