The script will be called by a dialplan extension, and when the script is finished, the call will be automatically hung up (see the Using conditionals, loops, web calls, and regular expressions recipe later to learn how to change this behavior and have the dialplan continue handling after the Lua script ends).

<include>
  <extension name="Basic Lua Script">
