First of all, you need to install the latest
Skype version, and to have a Skype account.
Next, you need to activate the SkypeOut service.
vCardOrganizer automatically enables you to call phone numbers with Skype, but

+ "area code" "phone prefix" "phone number" (e.g. +1 718 12345)
You can disable/enable the "Skype links" feature from the View Menu:
