I was going through my BlackBerry settings today and I stumbled on a feature I’ve never used before called FDN Phone List (Fixed Dialing Number), located in Options > Phone Options > FDN Phone List . The feature is an outgoing call blocking service native to your device. This seems like a useful feature for parents or companies that want to restrict the outgoing calls to either protect their kids, or keep bills under control.
