QoS "Appliance"

[notsure]

Hi All,

Since I got my new apple router (time capsule which includes an airport extreme) things are good except with VoIP.

Since apple doesn't do QoS (shame on them!!) I need some sort of appliance that will do QoS between the router and the dsl modem.

I've seen a couple of these devices but they seem to be very old (2005-2006).

Anyone have experience with something like this?

Putting linux on a PC to do this is not an option - nor is using a different router which does support QoS.

Thanks!
