New Revision: 392607

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=392607
Log:
Properly extract channel variables for the SendFAX/ReceiveFAX Stasis messages

By the time something extracts the pointers from ast_json_pack, the channels
will already be disposed of. This patch properly pulls the information out of
the variables and packs them into the JSON blob.
