[Freeswitch-dev] Localized Numbering Plans

[Raymond Chandler]

After seeing how many people responded to Brian's requests on localized 
say stuff, I figured I'd run this up the flagpole and see who salutes it....

I'd like to see FreeSwitch have localized numbering plans for many 
different areas out of the box. So, I've written a semi-complete version 
of a US numbering plan to spark some discussion on how others think it 
should be done.... and maybe get some examples written for other areas. 
If you notice any syntax errors, etc.... keep in mind this was written 
rather quickly and NOT thoroughly tested.... it's really just a 
(somewhat functional?) draft.

---- In Existing default_context ----
  <!--
  This will send a user to their localized numbering plan (provided the 
variable (maybe it should be a param?) is in directory.conf)
  -->
  <extension name="Localized_Dialplan">
    <condition field="${numbering_plan}" expression="^[[:alnum:]]+$"/>
    <condition field="destination_number" expression="^([[:alnum:]]+)$">
      <action application="transfer" data="$1 XML 
${numbering_plan}-Numbering-Plan"/>
    </condition>
  </extension>
