New Revision: 352199

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=352199
Log:
Fix blind transfers from failing if an 'h' extension is present.

This prevents the 'h' extension from being run on the transferee
channel when it is transferred via a native transfer mechanism such
as SIP REFER.
