managing traffic with TP-link TL-WR1043ND

I doubt I will get very far with this as i doubt any one got one of these routers, but I will give it a go.

i have got a Voip on broadband and most of the time it is fine, but if I am watching something on netflix and someone phones then the quality of the call suffers, even if I pause netflix, it also happens if I am downloading something.
I expect some degrading in quality as I am on 10 Mb/s, , with netflix or my download taking a fair bit of bandwidth.

there is something on the router called bandwidth control and it allows a ip address or a range of ip addresses to be set a minimum and maximum bandwidth, ingress and egress. but i don;t think that will do what i want.
I want say my ps3, which is what netflix is on to use as much bandwidth as it can and when i use the voip the bandwidth will reduce for the Ps3.

I know that my old ADSl netgear router would do.

so will this bandwidth system on my Tp-Link do the job?

As i said, i doubt anyone will know, but it is worth a go.

thanks
