How to install the SJphone voip phone on...

I spend hours trying to configure the SJphone to place so called 'voip calls' from my laptop but I couldn't make it work no matter what I did. I reread the manual from their official site a dozen times but the SJphone kept telling me it couldn't connect. I followed all the pieces of advice given in the SJphone help manual, ticked all the necessary boxes, still no improvement.
At last when I was about to dump all this, a friend of mine send me this voip phone link with detailed screen shots and instructions.
I set up my soft phone in a minute and made several calls. It was really exciting...
Hope this manual helps others too.

P.S.
BTW, I used the 'Continental' pc-to-phone from all other international calling cards.
