Has anyone had any luck with this? I noticed that if I turn the traffic 
shaping on or off, it doesn't seem to make a difference.  If I have one 
download going at full bandwidth and then try to make a call, I hear a 
lot of gaps and lag at first, then the call smooths out.  It does this 
with traffic shaping on or off, so I'm wondering if the traffic shaping 
is really making a difference for the VoIP phone.  From what I've 
discovered in testing out the traffic shaping, it doesn't really set 
packet priority, only the amount of bandwidth that is shared on a given 
pipe size based on the weight. I've tried creating just a few traffic 
shaping rules where a certain VoIP gizmo gets 99 weight queue of a pipe 
and everyone else gets 1 weight and I still see no difference between 
traffic shaping on or off for VoIP calls.  My theory is that VoIP 
traffic is just to small for traffic shaping to work with it, but I 
would like to hear what others think.
