New Revision: 393282
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=393282
Log:
Add states to delay between recall attempts.
Now the atxferloopdelay option actually does something! Yay!
In between recall states, the transferee will be placed on hold
for a brief period before attempting to recall the appropriate
parties.
