LOL? This is news to me. In which countries a phone connection is not terminated, if one side hangs up? Here in Germany the call definitely is terminated if one side hangs up and you would have to redial. And this behavior is not new, the phone network does behave this way since I can remember. With VoIP this is AFAIK the default behavior of most clients, too. (However, on protocol level, there is a 2 sided termination)
