Ive just had ADSL2 naked setup at my joint, and its working fine through my D-link modem(dsl200), but im trying to setup voip by using the linksys router. I think half of the problem is that the d-link modem is a usb modem and as such is slower and does not directly connect through router, I donno

ive connected the router to the computer and run the setup , but when i access the routers "web setup" by typing its ip in the IE addesss bar, I cannot access the voice tab(it says to contact server)
This being my first router/voip setup im pretty lost

Where should I start?
Thanks heaps,
Andrew
