Author: rizzo

New Revision: 45009

URL: http://svn.digium.com/view/asterisk?rev=45009&view=rev
Log:
arguments to auth_headers() needed to be swapped here.
To avoid the same mistake in the future (due to slightly
confusing variable names), add a comment.

On passing, remove a redundant initialization.
