The Movius for BlackBerry app is integrated with the BlackBerry Dynamics secure environment, separating it from your personal apps and having a blue floating icon that securely connects it with other BlackBerry secure apps.
The best way to make calls with Movius is to go directly through the Movius app and selecting a contact from the Contacts tab.
Movius also supports click-to-dial from BlackBerry Work, so you can conveniently click on a phone number in your BlackBerry Work email or calendar and be able to call directly from the Movius app.
