Sweet ya got it sorted as i Actually have a similar problem.....I have Telstra broadband but i use an internet phone, and if im downloading stuff off the net my phone wont work properly (i can hear people on the other end but they cant hear me ect) but if im just on the net (not downloading) then it works fine but sometimes (when this happens) i have to restart my whole computer for the phone to work

anywayz for the price i save on phone bills i will put up with the hassle
