Take SDP "Video" in the UAS send RED5 Brownser FlashPhone

I am working emcima project flashphone, and I know how to handle the sdp User’s caller.
So when I get the sdp, could send up his own browns using vlc own.

I have difficulty understanding the source code sipUserAgent.java, I just get my own sdp, but caught the second User, but when vlc does not play the game.
Does anyone could help me?
