what's the difference of rejecting packets in software, or because the
link can't handle them? Assume the guaranteed bandwidth is much lower
than what the link can provide (very common here during the day), the
isp will have to do the software thing anyways to balance the bandwidth
across the different ip.

it works flawlessy for me and it's the same problem (I also use
streaming services), and they're unusable until I turn the shaping on,
I'm sure that if you use the script and you change 1kbyte/sec to
everything but voip it'll work fine for you too, since basically
everything else won't pass anymore, it will take ages to open an html
page and all the bkbits.net users will hang, and the link will be idle
99% of the time, so voip will take it over as much as it can. I don't
think it's a matter of "if it works or not", I think it's a matter of
how much you're ok to lose in terms of global bandwith for all the other
services but voip.

the only annoying problem I run into, is that tc is missing a flush
operation (like iptables -F) but I never need to tweak it anymore so I
don't mind too much.
