	The disallow line must be set before any allow line.

	Since Asterisk has no official G723 support you should not even be
trying to use that.  Do you have the G.279 codec and license  installed
in your system?  Remember that G.729 is not included in Asterisk (as a
codec) so it only works in passthru.  You need to purchase some licenses
and install the codec for it to work.
