Jerry,
A Lua script that is explicitly called from the dialplan will indeed execute
dialplan-ish stuff. For example, let's say you had this in
conf/dialplan/default.xml:
<extension name="lua sample">
<condition field="destination_number" expression="9876">
<action application="lua" data="/path/to/myluascript.lua"/>
</condition>
</extension>
Then myluascript.lua has something like:
--Sample Lua script
session:answer()
session:sleep(1000)
session:streamFile("/path/to/file.wav")
session:hangup()
Assuming an otherwise default install, the above Lua script would execute
when a caller dialed 9876, or if a call was x-ferred to 9876.
However, if you're wanting to use Lua to serve up a dialplan then it's
totally different. Lua is not called from the dialplan; Lua provides the
dialplan to FreeSWITCH. This latter case is the scenario discussed in the
wiki section you referenced. (

Are you trying to use Lua scripting for serving up a dynamic configuration
of some sort?
