In this chapter we learned about the new functionality unleashed with mod_httapi. By combining a web server with FreeSWITCH it is now possible to do call control using the simple HTTAPI markup. Further, we also discussed a PHP library (phttapi.php) that provides an abstraction layer to make it even easier to build telephony applications on a web server. By using mod_httapi, enterprises can leverage the knowledge of their web developers to assist with creating telephony applications. Furthermore, web developers need not learn all that a FreeSWITCH administrator needs to know. Rather, they can learn just HTTAPI and still have everything they need to build feature-rich, web-controlled telephony applications.
In the next chapter, we will focus on a very important subject in today's converged world: Conferencing and WebRTC Videoconferencing
