Skype on my site

Hi everybody.
I’m not sure if it’s right forum, sorry if it’s not.
This site
allows online connect to Skype.
I search a long time ago how get that goal.
Per sample I’m using Openfire and I can connect to MSN, Yahoo, etcetera.
But all info found says there is not a way to connect to Skype from website.
Somebody knows at least what technology is using or somebody has some idea to help me ?
Thanks in advance

Why not just link to Skype and allow your customers to get in touch naturally?
