ncidClient is a client for the NCID (Network Caller ID) System that runs on iOS 7 and iOS 8 devices. It monitors incoming calls using a NCID server (which is provided by a VoIP-Box (like Vodafone EasyBox 602/802/803/903). The app automatically tries to match incoming land-line phone calls with data stored in your mobile iOS contacts to provide you with information about the caller (e.g. name, photo etc.). The information will be shown in a tidy arranged table. Please note that outgoing calls are not detected.
