How to create my first vocal service in VXML

Edit the incoming.php

<?php
echo '<?xml version="1.0" encoding="UTF-8"?> 
<vxml version = "2.0" xmlns=""; xml:lang="fr-FR">
<form>
<block>
      Coucou Maurice comment que ça va bien ! Ceci est un test de micro service avec Baratinoo !
  </block>
  </form>
  </vxml>';
?>

You must change the default configuration and indicate VXML in the configuration tab of your self-care.
