I get lots of random pauses during my Internet calls even though my Nokia N800 MAc address has top priority on my Tomato flashed router and it's the only application using bandwidth.

Any idea how to fix it? Any other software I could use?

I've tried Gizmo5, but the call stops after 1 ring after I dialed. And I can't seem to find where I could edit my SIP account settings.

Skype runs fine.
