Hotspot@Home Routers configuration for QOS

I am setting up a non T-Mobile hotspot @home router for the Blackberry 8320. Does any one have the IP addresses of what I assume are the WMA servers for T-Mobile so that I can set up QOS.

my router says the handheld is pointing to
n39.w104.t-mobilegws.com
n41.w74.t-mobilegws.com
psgw.t-mobilegws.com
when connected to UMA


If anyone has either the D-Link TM-G5240 or the Linksys WRT54G-TM
could they look in the QOS setup on their router configuration to see what servers they point to.

I have upgraded to 4.2.2.180 and it is still dropping calls periodically
Thank you in advance
