FreeSWITCH 1.8

Route DIDs to extensions

To route incoming calls that come in to a certain DID via the context public to a fixed extension in the context inhouse, do something like the following:

<context name="public"> 
   <extension name="test_did"> 
     <condition field="destination_number" 
       expression="^\d{6}(\d{4})$"> 
       <action application="transfer" data="$1 XML inhouse"/> 
     </condition> 
   </extension> 
</context> 

This will capture only the last four digits of a ten-digit number and transfer the caller to that number via the inhouse context. Note the parentheses around \d{4} that allow us to capture only the last four digits.
