Internal calls

Calling local extensions is very simple once you know what needs to happen. In this case, we will review how to add a new user and make his or her phone available to be called.

Getting ready

If you are using the default configuration, then users 1000 through 1019 are pre-configured, both in the directory and the dialplan. To create a user outside this range, it is generally easiest to just run the add_user script, found in the FreeSWITCH source directory under scripts/perl. For example, to add the user 1020, launch this script from the FreeSWITCH source directory, specifying the user ID on the command line:

 

scripts/perl/add_user 1020

You can also specify a range of users:

 

scripts/perl/add_user –-users=1020-1029

You will see a note about how many users were added. If you have the CPAN module Regexp::Assembly installed, then the script will also generate a 'sample regular expression pattern'. For our example, we will add a range of users 1020-1029.

How to do it...

Follow these steps:

1. Open the file conf/dialplan/default.xml in a text editor. Locate the Local_Extension entry:

    

1. <extension name="Local_Extension">
     <condition field="destination_number"expression="^(10[01][09])$">
     ...

2. Edit the expression in the <condition> tag to account for our new users. The expression pattern ^(10[012][0-9])$ will do what we need (look closely to see the difference). The new line will be as follows:

    

3. <condition field="destination_number" expression="^(10[012][09])$">

4. Save the file and then execute reloadxml from the fs_cli.
