Summary

In this chapter we have covered some of the many different use cases for FreeSWITCH, and we have seen how the different technologies that compose FS can be deployed using various techniques.

The key here has been the concept of toolset: FreeSWITCH is a focal point of real-time communication technologies that span the entire field, from billing to transcoding, from interactive voice attendant to least cost route management.

Also, we've seen how there are many ways to harness this power, to make FreeSWITCH cater to our own kind of users and business goals, using different tools for different aims, from XML to scripting languages, from databases to external services.

In the next chapters we will go deep into the rabbit hole, beginning with Chapter 2, Deploying FreeSWITCH, about production deployment best practices, that will show how to end up with a system that is reliable, manageable, robust, and performing.
