+; We highly recommend that you DO NOT turn on debug mode if you
+; are simply running a production system.  Debug mode turns on a
+; LOT of extra messages, most of which you are unlikely to understand
+; without an understanding of the underlying code.  Do NOT report
+; debug messages as code issues, unless you have a specific issue that
+; you are attempting to debug.  They are messages for just that --
+; debugging -- and do not rise to the level of something that merit
+; your attention as an Asterisk administrator.  Debug messages are also
+; very verbose and can and do fill up logfiles quickly; this is another
+; reason not to have debug mode on a production system unless you are
+; in the process of debugging a specific issue.
