Can anybody tell me for sure whether Vodafone will allow access to remote RTSP:// streaming media through their WAP gateway? I can't seem to get it working so my assumption is they allow access to their own RTSP feeds but block anything trying to use port 554 outside their realm.

Has anybody had any luck trying this? I was messing around with some real media encoded stuff on my WAP site using Helix server and can't get it going.
