【问题描述】：

如何从应用程序创建电话会议？

【问题讨论】：

让我建议 SuperUser（SO 的姊妹网站）作为这个问题的更好论坛：superuser.com

【参考方案1】：

我们必须：

开始通话 保持通话 开始新通话 加入会议 ...

要开始通话，请参阅来自Blackberry - make a call from native address book的api 没有 api 可以持有和加入，但我们可以使用 Blackberry - run menu item from dialer Phone App 技术 要将应用程序屏幕带回前台，我们可以使用来自Blackberry - Create an application which will lock another application event的代码

完整代码：

class Scr extends MainScreen implements PhoneListener 
    private static final String STR_MODULE_NAME = "SOConferenceCall";
    EditField mPhoneNumber = new EditField("phone number: ", "12345");
    boolean mConnected = false;
    Vector mPhoneCalls = new Vector();

    public Scr() 
        Phone.addPhoneListener(this);
        add(mPhoneNumber);
    

    protected void makeMenu(Menu menu, int instance) 
        super.makeMenu(menu, instance);

        if (isCalling()) 
            menu.add(new MenuItem("add to conference", 0, 0) 
                public void run() 
                    holdActiveCall();
                    makeCall(mPhoneNumber.getText());
                
            );
         else 
            menu.add(new MenuItem("call", 0, 0) 
                public void run() 
                    makeCall(mPhoneNumber.getText());
                
            );
        
    

    private void holdActiveCall() 
        runMenuItem("Hold");
    

    private void joinCalls() 
        runMenuItem("Join Conference");
    

    private void makeCall(String number) 
        PhoneArguments call = new PhoneArguments(PhoneArguments.ARG_CALL,
                number);
        Invoke.invokeApplication(Invoke.APP_TYPE_PHONE, call);
    

    private void runMenuItem(String menuItemText) 
        Screen screen = Ui.getUiEngine().getActiveScreen();
        Menu menu = screen.getMenu(0);
        for (int i = 0, cnt = menu.getSize(); i < cnt; i++)
            if (menu.getItem(i).toString().equalsIgnoreCase(menuItemText))
                menu.getItem(i).run();
