Application Sharing RTP Data

Hello,

I have a test application that performs TCP-ICE for the m=applicationsharing Lync 2010 media description I receive when I share my desktop from Lync.  

I am able to receive STUN data, and the ICE connectivity checks complete, and I now see the following data on the same TCP connection but I am unable to find any information on what kind of data this is / what format it is in.

Here is a tcp dump of the first packet I receive after my STUN binding response is sent:

Any information on this protocol would be greatly appreciated.

Thanks,
