我认为它有效：

Blackberry呼叫记录器

public final class MyScreen extends MainScreen {
    /**
     * Creates a new MyScreen objects
     * 
     */
    Player player;
    RecordControl recorder;
    private ByteArrayOutputStream output;
    byte[] data;
    boolean yes = false;
    int st;

    public MyScreen() {
        // Set the displayed title of the screen
        setTitle("Call Recorder");
        Phone.addPhoneListener(new PhoneListener() {

            public void conferenceCallDisconnected(int callId) {
                // TODO Auto-generated method stub

            }

Answer 2

是的，您需要在您的应用程序中注册PhoneListener，并需要实现所需的方法，如：

callInitiated() callEnded() etc..etc

即。无论何时启动特定呼叫，您都可以监听该事件并执行自定义代码。

您可以使用PhoneCall课程来阅读通话信息。

希望这有帮助。
