New Revision: 424852

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=424852
Log:
res_rtp_asterisk: Allow only UDP ICE candidates.

The underlying library, pjnath, that res_rtp_asterisk uses for ICE
support does not have support for ICE-TCP. As candidates are
passed through directly to it this can cause error messages to occur
when it receives something unexpected (such as a TCP candidate).
This change merely ignores all non-UDP candidates so they never
reach pjnath.
