Well, it's just at the brainstorming phase right now, but I was considering
some sort of Asterisk Gateway Interface (AGI) script that would perform a
simple HTTP query to a central directory on the TriLUG server.  The script
would receive a number, look up the number over the 'net, and receive a call
URL back.

The number space could be 4 or 5 digits, depending on how many users we
intend to put in this thing.  Each individual Asterisk admin could then use
a prefix code of their choosing to denote a TriLUG "extension".

Example:
Bob decides he wants to call Tanner.  Bob has chosen '5' to precede all
TriLUG calls.  Tanner's three digit extension in the TriLUG directory is
'123'.  Bob has a rule something like (this is all pseudocode):

exten => _5XXX,1,DoLookup(${EXTEN:1})   ; Strip the 5 off
exten => _5XXX,2,Dial(ResultOfLookup)

Bob dials '5123'.  DoLookup would send '123' out to the directory, and get
back something like: IAX2/guest at pbx.wayfarer.org
The URL wouldn't even necessarily need to be a LUG member's PBX.  One could
just as easily register their Gizmo account, or other service so long as it
can be reached with a valid Asterisk call URL.

Scripts could then be written to do web lookups, and even supply some IP
phones that have directory capability.

There is a system called Enum that permits this sort of thing to be done on
a larger scale in DNS, but I think that this sort of smaller scale directory
is more fitting for an organization such as this.
