Summary

In this chapter, we discussed the following:

• How AAA (Authentication, Authorization, Accounting) concepts are implemented in FreeSWITCH
• How FreeSWITCH collects users into a directory
• How FreeSWITCH uses information fro User Directory and Dialplan to route calls from users to each other, and to the world
• Employing various user features such as voicemail
• Adding a new user and modifying the Dialplan accordingly
• Connecting to the outside world with gateways
• SIP and Verto profiles

In this chapter, we made modifications to the default XML Dialplan, and we learned how to set up users and domains within the XML user directory. Also, we saw how to setup SIP gateways and DID numbers to interconnect with the external world. In the next chapter we'll have a first look at WebRTC and Verto, powerful technologies that promise to seamlessly integrate browsers, mobile apps and the Internet of Things (IoT) into our FreeSWITCH communication platform.
