Block phone useage on a Windows Mobile 5 device

Question

I am developing a Windows Mobile app that my company is providing the devices for. We do not want our users to use the phone that is part of the windows mobile device.

Does anyone know a way to block phone usage?

If it matters, the device type is a Symbol MC-70.

Thanks in advance for any input.

Answer 1

Best I could come up with was to use the Telphony api provided at:http://tapi.codeplex.com/

It has a CellularLineMonitor class that allows me to hang up on any call after it is made or received.

Answer 2

If your company is providing the devices and you do not want users to use the phone, you should get a data-only plan from your provider. This will save your company money and ensure that the phone cannot be used.
