8.1. Diagnostic Messages 
Before troubleshooting a problem, check the indication of the connection status in the notification bar. For example if connection to the internet is lost there will be a "No Data connection" or you might see a "Callback mode" message in the OpenScape Mobile Pro notification bar. On an Android phone swipe down to expand the notification bar.
