asterisk users - Nov 2005 - Invalid/Timeout handlers in ael?

Does anybody know how to code invalid and timeout handlers in ael macros?

I tried the following, but no luck.

========macro call-screen() {
	NoOp(Macro call-screen);
	Background(privacy-screening-unidentified-calls);
tryagain:
	Playback(pls-rcrd-name-at-tone);
	Set(SCREEN_FILE=/tmp/screen-${EPOCH});
	Record(${SCREEN_FILE}.wav,6,25);
	catch i {
		NoOp(invalid?);
		goto tryagain;
	}
	catch t {
		NoOp(timeout?);
		goto tryagain;
	}
};

As far as I (don't:-) understand asterisk sources, extensions 't'
and
'i' can be used in _context_ only, but not in macro. Application
voicemail has a special handling for 'a' extension to allow it in macro.
