Correct me if I'm wrong, but VoIP uses UDP connection and other applications mostly use TCP connection. And as far as I know, UDP doesn't have congestion control as TCP so UDP will crowd out TCP traffic which means, that VoIP will always have priority, as TCP connection will lower its transmission rates. In that case you don't really need to use QOS.WelshPaul wrote: QOS only really kicks in when it needs to, so if 'the son' was playing GTA 5 online and a VoIP call comes in his gameplay might not cause any issues bandwidth wise, if it does then QOS kicks in and VoIP traffic becomes a priority, that doesn't mean 'the son' can't continue to play GTA 5 or that he would even notice a difference in some cases.
