Hi,

We operate Zebra TC57 handhelds managed using Mobicontrol.   The Zebra handhelds come with a default phone dialer app - org.codeaurora.dialer

Our handhelds are really well locked down (using the various Mobicontrol and StageNow features) except when this dialer is invoked for incoming/outgoing phone calls.   The app allows the user to get out to things like bluetooth share, mms messaging, file system, web browser, camera, video, slide show etc.   

While we could try and disable each of undesired functions the dialer gives access to (for example SOTI Surf is stopping the user's unauthorized browser access), it would be really good to instead provide a really basic phone dialer to make and receive calls.   I haven't been able to find anything suitable.

Has anyone has any success in loading an alternative basic phone/dialer?, or has any other ideas on locking these functions away from the user?

Many thanks, Lindsay
