Summary

In this chapter, we have introduced Asterisk as an open-source PBX with just a glimpse of the hundreds of features that are built into the system. There are many other features, and since Asterisk has a built-in programming language, many new features can be, and have been, added by end users and programmers. We will see some of these customizations in the later chapters. We also have an idea of the history of Asterisk and why it came into fairly popular use. We have information on websites and books for further information on Asterisk, if necessary. However, from now onwards we will be very TrixBox specific with our discussion.
