Hi,

You can use mod_xml_curl (generate xml on a webserver):

http://wiki.freeswitch.org/wiki/Mod_xml_curl

or mod_xml_odbc (generate xml in freeswitch):

http://wiki.freeswitch.org/wiki/Mod_xml_odbc

or LUA together with luasql (generate xml in freeswitch):

Or, if you're really crazy, the erlang module can do it too (even dynamically): http://wiki.freeswitch.org/wiki/Mod_erlang_event#XML_search_bindings :P Andrew

I have a bit of confusion about Lua scripting. When a script is invoked, should it always return an XML string that is used by FS? Or as in the case of dialplan examples, does it actually execute the dialplan (e.g. "session:answer();")?

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.

MC, We would like the dialplan to route the call based on Presence, which is a database lookup. I should be able to do this in Lua, true?
