[SVN commits to the Digium repositories]

Author: mjordan

New Revision: 351233

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=351233
Log:
Fix udptl issue with initial INVITE introduced by r351027

When an inital INVITE occurs that contains image media, a channel
is not yet associated with the SIP dialog.  The file descriptor
associated with the udptl session needs to be set in
initialize_udptl or in sip_new to account for this scenario.
