index.php

• Change 1:Code added at beginning of index.php

   // Post Processing in case voiceXML is enabled
   if (voicexmlenabled()) {
       ob_start();
   }

• Change 2:Code Added at the end of index.php

   // Post Processing in case voiceXML is enabled
   if (voicexmlenabled()) {
       $output = ob_get_contents();
       $output = post_process_voice($output);
       ob_end_clean(); 
       echo $output;
   }

• Alternatively - Better Solution

   Change 1 code included in print_header() function in weblib.php
   Change 2 code included in print_footer() function in weblib.php

 - This will minimize the change in code. As all pages already have the above two functions. I have tested the code for index.php and need to extend it to other pages.
