      I have an Asterisk box on a static IP which is the only thing in the Voip up/down queues.  Connection is 6000/768 dsl.  PfSense 1.0.1.

      Queues (leaving out the lower priority ones that don't matter)

      0  No  730 Kb    qwanRoot
      0  No  5700 Kb    qlanRoot

      ACK    7  No  25 %    qwanacks
      ACK    7  No  25 %    qlanacks
      These both have the ACK/low-delay queue.  Both are set to 10% m2 on real time.

      7  No  25 %    qVOIPUp
          7  No  25 %    qVOIPDown
      Real time is: 400Kb 5000ms 192Kb on both queues.

      I am not showing ANY borrows, suspends or drops on ANY queues when I look at the Status:Queues page.

      Running multiple Voip providers, all with ulaw codec (which uses 64Kb/s).  Rare that I would have 3 simultaneous calls, so 192Kb seemed safe.  I am getting intermittent drops during the calls, mostly during the first 60 seconds.  Which makes me think it has to be the traffic shapper config.  Anyone got any recommendations?

        qwanack is quite small. Please have a look at

        Also, try qwanroot = 600 kb/s, qlanroot = 4800 kb/s. Sometime it helps.
