sipdroid/gizmo 5 being blocked on verizon 3g

I see the same symptom with sipphone.com (gizmo5) and sipgate: Sipdroid connects fine via wireless but not 3G on Verizon using my Droid Incredible. On 3G, Sipdroid's connection indicator goes yellow for awhile, then appears to timeout and go red. This problem started at least a week ago.
