The complete application is made up of various files:

  • welcome.lua: This is the main script

  • utils.lua: This contains the utility functions provided to all other scripts

  • LuaRunMoh.lua: This script is spawned by welcome.lua for non-blocking audio playback to the caller.

  • welcome.xml: This is the dialplan entry

Because we will often reference different parts of the scripts you really must download the code from www.packtpub.com.

You will then load mod_flite into FreeSWITCH, because this script needs Text To Speech (TTS). If you have compiled from sources, go to /usr/src/freeswitch.git and type (pay attention to dash-underscore differences):

makemod_flite-install
