Chapter 10. Advanced IVR with Lua
And now for something completely different!
In both of our cookbook and FreeSWITCH book you can find different examples and snippets of basic and intermediate Lua FreeSWITCH scripting. I will not repeat that.
What follows in this chapter is a moderately complex IVR application that makes use of different Lua FreeSWITCH techniques: logging, nesting, multiple files, setting and getting channel variables, accounting, asynchronous execution, web access, database access, error handling, post-hangup execution, functions, and so on.
Because this is not a basic snippet, and because it must strike a balance between comprehensibility and number of pages, I ask you to be patient and to bear with me while I describe the various steps.
I promise you will find reusable techniques, common patterns, and perhaps some inspiration.
