EZ IVR Part 2.b of 3 - the demo of execution (call transfer)

*Organized in geocities: http://www.geocities.com/rakabali78/ezivr.html

Part 1. : http://www.youtube.com/watch?v=W6JEyjkt7RM
Business overview.
In this part the (business) use of this application is explained.

Part 2.a : http://www.youtube.com/watch?v=GdgU_YEzyQA
Demo execution - intro.
In this part the cases that will be demo-ed in the subsequent videos are explained.

Part 2.b : http://www.youtube.com/watch?v=QsLnwuPMfwY
Demo execution - cases 1 & 2 (call transfer, succeeded) and 3 & 4 (call transfer, rejected).
For case 1 & 2, the call transfer is answered by the callee.
For case 3 & 4, the call transfer is rejected by the callee.

Part.2.c : http://www.youtube.com/watch?v=mzmU9WfUMvg
Demo execution - case 5 (call transfer, busy, queued, with one caller)
For case 1 & 2, the call transfer failed because the callee is busy, so the caller is asked whether she wants to wait in the queue.
There's a timer for each element in the queue, that timeouts after a couple of seconds (45 in this demo), and checks the current position in the queue; if it's the 1 (the first) the call-transfer will be retried.

Part.2.d : http://www.youtube.com/watch?v=SnxwNENKev0
Demo execution - case 6 (call transfer, busy, queued, two callers).
Same as case 5, but with two callers. Here we verify that the positions are calculated correctly, and that the queue actually moves (so when the element that was first in the queue terminates the call, the element that directly followed it will move forward in the queue).

Part.2.e : http://www.youtube.com/watch?v=mWVrXUYjIX4
Demo execution - case 7 (play a message in the IVR).
In the IVR tree you can configure some "messages node". The subscriber can use it to allow callers access announcements / advertisements through the IVR.

Development info.
Here I explain the modules that make up this application. I also explain the pattern that I employed when I implemented this application. Lastly, I glazed over some testing concerns & challenges.
