In this chapter, we discussed the following:
How FreeSWITCH collects users into a directory
How FreeSWITCH uses a VoIP protocol, SIP, to connect users to each other, and to the world
SIP is similar to e-mail in that it has users and domains
Employing various user features like voicemail
Adding a new user and modifying the Dialplan accordingly
Connecting to the outside world with gateways
SIP profiles and user agents
In this chapter, we made some minor modifications to the default XML Dialplan, and we learned how to set up users and domains within the XML user directory. Now that we have a general understanding of how these modifications work, we will continue to build upon this foundation. We will now begin to form a much more detailed understanding of FreeSWITCH as we further explore the XML Dialplan module, the default and most commonly used call routing engine available in FreeSWITCH.
