nortel switch and VoIP

My knowledge is very limited when it comes to switches I have a Nortel BES 120 that I’m not using. My problem is I have a computer in the back room that I use for network storage and I have a Magic Jack for VoIP calls. Problem when I’m using a bit torrent program to download on another networked computer the VoIP quality drops to where I almost can’t use it (there is about a 5 second delay at least). Can I use the switch and set up Qos say on the port that the VoIP computer would be plugged into so solve that problem.
Thanks
Rick

Yes, you can set up independent QOS\Traffic Prioritization in the Nortel per Port; I guess the question is are you familiar enough with that particular Switch to access the Console and\or GUI? It is a very straight forward procedure once you can get to the config settings. I might also suggest to you simply limit the Bit Torrent Bandwidth from your BT Client....that would be a very quick and dirty solution with basically the same end result. One way or the other, you will need to take a Bandwidth hit somewhere.......let us know how it goes.
