New Revision: 50468

URL: http://svn.digium.com/view/asterisk?view=rev&rev=50468
Log:
Remove check for channel state as it can definitely be something other then ring, and also clean up the code a bit. This should solve the parking issues and maybe some attended transfer issues people have been seeing.
