The only real solution, for the scenario where this happens, would be to somehow identify all the BitTorrent traffic and stuff it into a single bucket, where it has to compete on equal terms with the single VoIP flow.  The big unanswered question is then: can this realistically be done?  Does BitTorrent traffic get marked as the bulk, low priority traffic it is, for example?
