[Freeswitch-users] Dynamic Dialplan

[Anthony Minessale]

That's why I chose mod_xml_curl as a demo for the xml_hook api.  It's not
only a demo, it's rather functional =D

You have 2 choices other than using the stuff we already have in tree.

1) write a custom dialplan module, this module gets a single callback
function a dialplan_hunt function that has the session and the caller
profile.  you can see from mod_enum or mod_dialplan_xml how this can be used
to make your own module that looks in a db and returns instructions to FS on
the fly.

2) write a custom xml_hook and use it with mod_dialplan_xml, this type of
module embeds itself into the xml lookups so when something tries to find
something in the xml registry, your function is called and you can do your
db lookups and generate the xml returned as binary xml obj built from a
result of the query.  This is more powerfule because it allows you to
pre-empt any xml lookups so you can deliver directory, config, dialplan,
phrase macros, etc


mod_xml_curl is an example of #2, it turns the xml_req into a url req and
feeds the xml returned over the http socket into an xml object and returns
it as the result in place of the static contents of the xml file.
