When you try to call a landline number from skype for iphone without having an account/credit, the call isn' t carried out, but it doesn' t close the call screen either. It just keeps showing it calls and you can only exit the skype app itself. That' s all.
I recommend to download the latest Skype and search first.
To get the most out of Skype I recommend Skype Premium.
