In this 8-minutes video we learn how to deal with the provisional responses (such as the ringing signal), success responses (such as OK), and the bye requests. This is the continuation of this video, where the application we’re developing is explained, and the way we handle the initial invite-request from the caller is explained.
The upcoming video will be about implementation of click-to-dial application, and it would conclude chapter 4.
I also decided to create a mini chapter that follows chapter 4 – I’ll name it… chapter 4 extra – where I make the test calls to and trace analysis for each SIP servlets explained in chapter 4.
There’s one more thing: the source code for chapter 4 is available in this URL: http://www.box.net/shared/tk4ghghllg. It’s a netbeans’ project folder. Use Netbeans 6.x and follow the instruction in this video in order to be able to compile those codes successfuly.
I hope you enjoy the videos! Zaijian!
