It will take you from being a novice to creating a fully-functional telephony system of your own. It is rich with practical examples and will give you all of the information and skills needed to implement your own PBX system.The book begins by introducing the architecture and working of FreeSWITCH before detailing how to plan a telephone system and moving on to the installation, configuration, and management of a feature-packed PBX.

Getting started with Lua


Enabling Lua (via mod_lua) is very similar to the process we used in Chapter 2, Building and Installation, where we enabled mod_flite. It is done in the following way:

  1. Open modules. conf in the FreeSWITCH source directory and locate the following line:

    #languages/mod_lua

    Remove the # and save the file.

  2. Open modules.conf. xml in the conf/autoload_configs directory and locate the following line:

    <!-- <load module="mod_lua"/> -->

    Remove the <!-- and --> tags and save the file.

  3. Build and compile mod_lua from the FreeSWITCH source directory:

    make mod_lua-install
    
  4. Wait for the installation to finish, and then restart FreeSWITCH. Launch fs_cli and type show application. If Lua loaded successfully, then you will see that lua is now available as a Dialplan application as follows:

    lua,Launch LUA ivr,<script>,mod_lua
    

You are almost ready to write scripts in Lua.

Note

Later versions of FreeSWITCH have mod_lua enabled by default.
