A while ago a friend tried something similar. He concluded SIP UDP packets are blocked or filtered out. He enabled VPN and connected directly with his office PBX without issues. It just appears that SIP audio traffic is blocked. However as with Patrick, the IAX protocol worked without any VPN or traffic modifications/re-routing to other ports.
I'm still curious about what you are doing and accomplishing - but I am equally curious with the Windmobile Internet service for both the SIP protocols and the latency period. *Cheers!
