ENUM Support

mod_enum can be used as a dialplan app, an api call from the console or as a dialplan interface.


Dialplan Interface:
put enum as the dialplan parameter in an endpoint module
i.e. instead of "XML" set it to "enum" or "enum,XML" for fall through.

Dialplan App:
This example will do a lookup and set the a variable that is the proper
dialstring to call all of the possible routes in order of preference according to 
the lookup and the order of the routes in the enum.conf section.

<extension name="tollfree">
  <condition field="destination_number" expression="^(18(0{2}|8{2}|7{2}|6{2})\d{7})$">
    <action application="enum" data="$1"/>
    <action application="bridge" data="${enum_auto_route}"/>
  </condition>
</extension>

You can also pick an alrernate root:
<action application="enum" data="$1 myroot.org"/>	


API command:
at the console you can say:
enum <number> [<root>]

The root always defaults to the one in the enum.conf section.
