程序可以在一次通话使用实用下列方法捕捉挂机键。请注意这里需要SwEvent能力，以确保通知Window Server函数的成功调用。

#include <W32STD.H> // link against ws32.lib
#include <e32keys.h>
...
RWindowGroup& groupWin = CCoeEnv::Static()->RootWin(); 
TInt endKey1 = groupWin.CaptureKeyUpAndDowns( EStdKeyNo, 0, 0 );
TInt endKey2 = groupWin.CaptureKey( EKeyNo, 0, 0 );
// -> End key can now be processed before the phone application of the device...
...
// Cancel the capture
groupWin.CancelCaptureKeyUpAndDowns( endKey1 );
groupWin.CancelCaptureKey( endKey2 );

该解决方案已在Nokia N73(SW: 2.0620.0.05)上经过测试
