New Revision: 79857
URL: http://svn.digium.com/view/asterisk?view=rev&rev=79857
Log:
Fix some crashes in chan_sip. This patch changes various places that add items
to the scheduler to ensure that they don't overwrite the ID of a previously
scheduled item. If there is one, it should be removed.
(closes issue #10391, closes issue #10256, probably others, patch by me)
