Section 2 is finished – finally.

These two videos below close the chapter 2 of the “IMS application development tutorial” video series.

In the first we make a comparison between the call we made through SIP proxy and the call through back-to-back user agent. At the end of it I explain the reason why – in my opinion – we are more likely to develop back-to-back user agents (using SIP servlet technology).

The second video contains the demo of the EZ-IVR application (that's the complex application we are going to develop at the end of this video tutorial -- chapter 6, 7, and 8 -- utilizing all the knowledge we acquire throughout the preceeding chapters). In addition to the demo, the video also gives a quick overview of the interaction between the elements that make up the application.

Well, that's all for section 2. I learned something from this process: I did it the wrong way (I mean, the technique of making the video), that's why the process was slower than I expected. In the upcoming chapters I'm going to record all my activities on the screen first (without saying anything), and do the voice-overs after that.

What about chapter 1? A good news: a friend of mine is going to help me with that. He's more knowledgable and experienced in this area. I'm glad and honoured to have him in this video. Chapter 1 is going to be an interview with him. We're still working on the script, expect to see the video in 7-10 days from now.
