Let's create a brand new extension. Start by opening the conf/dialplan/default/01_custom.xml file we created in Chapter 4, SIP and the User Directory. This file will contain the custom extensions that we will create from now on.

Tip

Always begin your custom Dialplan filenames with a digit sequence. The reason for this is that the XML parser reads the XML files in the order represented by their ASCII filenames. The last file at conf/dialplan/default/ that we want parsed is 99999_enum.xml. This file contains the ENUM extension that is used as a last resort if the dialed number does not match any other extensions. See http://wiki.freeswitch.org/wiki/Mod_enum for more information.

A Dialplan XML file can contain one or more extension definitions. The only restriction is that the file should begin and end with the XML tags <include> and </include> respectively.
