Re:QOS should work (Score 1)

Actually, if you set it up properly, QoS should work.

First of all, you need to combine QoS with traffic-shaping. (QoS tagging doesn't do you any good if you don't act on those tags) Second of all, you need to use that traffic-shaping to limit both the egress AND ingress BT traffic to reserve enough bandwidth for your VoIP traffic (e.g. 90% of your bandwidth, or something like that). It helps to have the type of internet connection where your bandwidth rates are constant so that it's easier to calculate how much to allow for BT traffic. The back-off algorithms in the TCP stacks will throttle back when you start dropping packets.

Anyways, it IS possible to throttle ingress traffic, but only if you're trying to throttle TCP traffic. Ingress throttling isn't quite as effective because you're on the wrong side of the bottleneck, so you might need to add a little more margin to your ingress traffic-shaping.
