In this chapter we learned about the conferencing capabilities of FreeSWITCH. After a brief overview of audio and video conferencing techniques, we saw how they are supported by FreeSWITCH.

We learned how to setup audio conferences in FreeSWITCH, with their multiple features. And how to extend that setup to provide the newest video capabilities, and WebRTC interactions.

Then we saw how to manage and operate a conference from FreeSWITCH console, how to call into it from dialplan, and how to call out from it interactively.

We closed this chapter with a visual presentation of Verto Communicator features and functionalities for both conference participants and moderators.

We're ready to implement leading edge conferencing services for our users!

In next chapter we'll learn all about the dreaded enemy of telco implementors: NAT, and how FreeSWITCH has been designed to pass through it.
