Does anyone use Jahah?

[Scouzer]

So Jahah being cheap and getting reasonable reviews I'm giving it a shot to replace my dead Dialpad...

And I can't figure out how the feck this thing works! It 'calls' in my browser, and it does ring on the other end...but nothing happens on my end! I used a headset, which it says is not necessary? What the heck do I use??

Does anyone have more clue than myself? heh...
