Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "Asterisk provides a number of defaults and we can configure additional ones in the /etc/asterisk/indications.conf file."

A block of code is set as follows:

[default]
mode=files
directory=/var/lib/asterisk/music-on-hold
random=yes

Any command-line input or output is written as follows:

#!/bin/bash $ tar xjvf asterisk_backup.tar.bz2 $ cp -R etc/asterisk /etc/asterisk

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Once installed you will find the Backup & Restore module located under the Tools section of the GUI ".
