Packet loss probably isn't even a factor. Your QoS configuration is only going to affect traffic *from* you, unless you can ask your ISP to prioritize VoIP traffic *to* you you're only tweaking one direction. Plus QoS isn't going to interrupt a packet currently being transmitted, if a large download packet is already going out your VoIP packet is gonna have to wait until its done. The slower your connection the worse the latency can be. -- [EMAIL PROTECTED] "The avalanche has already started, it is too Rod Dorman late for the pebbles to vote." - Ambassador Kosh
