From Skype Journal, although the permalink for the article is currently 404:
Effectively without telling you Skype has raised the cost of every Skype Call. They call it a connection fee. So you make a less than 30 second call and leave a quick voicemail. In the good old days of SkypeOut this action cost you 2 cents. You would probably be surprised to learn that today the same call will cost 6 cents. Not much if all your calls are one hour long. A huge amount if the other person isn’t there.
I’m getting ready to start using the Pro version of Pamela to start recording video… should I be holding off?
