In our application we have the same configuration (same port:554) used for vod streaming and for the live streaming.
The problem is with android, the playback of the live is well but for the vod it crashes.
The problem is just with 3G connection.

My question if my carrier blocks some ports for rtsp,Why my live application is well?

For information, We have the same result when testing the example at www.wowza.com/demo:
