Failed to find param [username] with TINYDEMO.EXE about boghe HOT 2 CLOSED

As you are a newbie, I think it's easier to use scenarios. You have many 
example in the current folder. A scenario has ".sn" as extension.
Let's get an example: 
http://code.google.com/p/doubango/source/browse/trunk/tinyDEMO/open-ims.test.sn

-Line 9: "192.168.0.13" is the server ip
-Line 10: "4060" is the server port
-Line 39: register to the server
-Line 45: Pause the execution until the user press "ENTER"
-Line 47: Make audio call to johndoe. To make audio/video call use "++av" 
command
-etc etc...

To start the demo program with this scenario: "tinyDEMO.exe ++sn --path 
./open-ims.test.sn"
