New Revision: 425644

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=425644
Log:
res_rtp_asterisk: Fix a bug where ICE state would get reset when it shouldn't.

In the case where the ICE negotiation had not yet started current state would
get wiped when it shouldn't.

This also removes channel binding as in practice this does not work well with
other implementations.
