Reserve more outbound (qVOIPUp queue) bandwidth for vonage. Also, shrink the outbound bandwidth on the root queue (qWANRoot). You might be slightly starving the VOIP queues. You didnt' mention what type of provider you have, but here are some useful tips. No ISP gives you the exact bandwidth you pay for (unless you are a business class customer - and even then, look at your contracts). ALTQ needs a little headroom to queue packets - I'd recommend shaving off a couple dozen Kbit/second - but this is where traffic shaping becomes a fine art...shave off until it "feels right". PPPOE has overhead. A 768K circuit is 768K _inclusive_ of the transport - which will likely include PPPOE framing and probably ATM framing. A good rule of thumb with PPPOE is to subract close to 20% of your circuit speed (again...tweak until it starts sucking and back off a hair). VOIP is extremely sensitive to dropped or delayed packets - put a max ceiling on your P2P if this becomes a problem. Make use of the artificial ceiling that most BT clients have, don't rely on the shaper to do it for you. Traffic shaping helps, but it's not perfect. Bottom line is that an oversubscribed line is going to suck regardless of how you tweak the shaping - although you can make it tolerable with shaping as opposed to completely intolerable. The wizard is a good starting point (we need people to document it well).
