[Asterisk-Dev] [patch] - app_directory RealTime support

[Matthew Boehm]

http://bugs.digium.com/bug_view_page.php?bug_id=0002475

tada! app_directory with RealTime support. I need some testers to test it
with other RealTime drivers.

The patch allows app_directory to use RealTime ability and retrieve
directory information out of the voicemail database AND the voicemail.conf
file. (YES! It works with both! am i a genius or what?)

But wait! There's more!

If you use the option 'hidefromdir=yes' you can keep a person(s) from being
listed by the app! Wow! (Disclaimer: hidefromdir ability only valid with
RealTime)

(Sorry for being so giddy but earlier this morning someone quoted me to
someone else on the -users list and I've felt so great. So awesome to be
quoted by someone to someone else.)
