Hi, I'm having problems with VoIP phone services when I enable QoS. I tried this with 2.0 and 2.1b1 on my WRT54G V3. I put 3 MAC addresses (I have 3 ATA boxes) in High priority. When I save the page, I get a prompt that says something like enabling multiple devices would defeat QoS's purpose but can still save the settings. Once I do this and enable QoS, none of my VoIP services work; the boxes can't register. If I disable QoS, all boxes register fine and everything works fine. Any thoughts ? I don't have any special firewall settings. Thanks for any help.
