How to handle End Call Key in 3rd edition?
By default, the End Call key simply quits the application in 3rd Edition (see Archived:Call termination key behavior has changed from S60 2nd Edition FP3 (Known Issue))

Sample code as follows:
void CExampleAppUi::HandleWsEventL(const TWsEvent &aEvent,

//Send your app to background or Exit from the application
