MC40 Voice BSP RevB and PTTExpress

Customer is interested in the Zamboni VOIP client but not interested in the PTT Express client.  When I load and install the Voice BSP to the device, PTT is installed and present at the top of the screen.  Even by disabling the service, I still see the icon show up.  Only method I've found to remove the PTT Express Icon from the notification bar is to go into Settings>Apps>All, select PTT Express and either remove the "show notifications" selection or disabling the service from within this configuration.


Using a MDM tool like Soti, is there an easier method to controlling PTT Express notification status?
