Hello, I'm trying to get lossless VoIP traffic over my 3000k/500k ADSL line. Shaping outgoing traffic is no problem: I set total ceil for outgiong device (ppp0) to 450kbit and put VoIP into highest prio class. Even during full upload the voice is clean on the other end. Now I tried to get the same result for incoming data. I attached HTB to eth1 where the incoming voip traffic is forwarded to. But even when I set the ceiling for other traffic as low as 800kbit there are drop outs in incoming voice while "full" downloading. Could I setup HTB better than below? Should I reduce eth1's queue length (now 1000)? If yes, how? Thanks.
