    17 The data in these files are used by the feature manager to create a configuration

    18 at run time. For testing the features on emulator a sample configuration file

    19 is located in <codeph>ctsy/test/component/data/features.dat</codeph>  </p> <p><b>Emergency calls in offline mode </b> </p> <p>Emergency calls can be made
