Another WiFi Calls issue with the 8520 that none of the fixes fixed

I just purchased the Blackberry 8520 through the t-mobile carrier. The router I'm using a a Belkin.

My issue...
when I attempt to make or receive wifi calls on the phone I cannot hear anything. The phone connects fine and from talking to my friends they can hear me, but I can't hear a thing. On the t-mobile network the phone performs fine. I've tried almost every wireless channel for my router and still a no go....Please someone help me!!

Check out the Wifi How to guide in my signature below... if after reading more than just the first post you still have issues... then check out the UMA guide, also in my signature below.

And then since this is your first post... do a Battery Pull: Leave your device on, pull the battery for 20 seconds, put the battery back in and wait for your device to boot up.
