HTB is a bad choice for VoIP. When it "borrows" bandwidth, according to the docs it doesnt release it back until its finished so if its using all the bandwidth for a download before the VoIP call starts, VoIP gets starved even if you reserve an excess of bandwidth as it still queues. When I tried it sort of worked but didnt have the effect I expected on a busy link, probably for this reason.
HTB tries to be fair about sending packets but with VoIP being fair sucks :) A better way is to use a "prio" filter at the root, the priority 1 branch having a plain fifo on it - send VoIP and acks only this way. The priority 2 branch has a HTB hierarchy with sfq leaves for the rest of the traffic. This seems to work much better, but I have not tested well yet. I am also using a police filter for incoming (on ADSL) and have not noticed any problems - but it is only lightly limiting (to try and keep the queues at the ISP end short.) Lastly, test to make sure the packets are flowing where you expect them to - I had to correct a few miss-understandings I had on how it all worked before everything went where I wanted it to :) TC and TCNG do seem dead, but I think thats partly because its relatively mature and doesnt need much work.
