The company directory

Most companies have some form of dial-by-name directory. This recipe will show you how to add a company directory to your FreeSWITCH installation using mod_directory.

How to do it...

Enable and build mod_directory by following these steps:

  1. Open modules.conf in your FreeSWITCH source directory.

  2. Uncomment this line:

    #applications/mod_directory

  3. Save the file and exit.

  4. Linux/Unix users have to issue the proper make command:

    make mod_directory-install

Allow mod_directory to be loaded when FreeSWITCH starts:

  1. Open conf/autoload_configs/modules.conf.xml in a text editor.

  2. Uncomment this line:

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

  3. Save the file and exit.

  4. Restart FreeSWITCH.

  5. Start fs_cli and issue the command show application.

You should see an application named directory in the list. Next, we need to add a simple dialplan extension that will let us test:

  1. Open conf/dialplan/default/01_Custom.xml in a text editor.

  2. Add these lines:

    <include>
  <extension name="dial by name"...
