Good ol' Telkom doesn't like Skype
From an article on itweb, it's hilarious:
“As far as Telkom is concerned, ‘network bypass' software is illegal and - although it is difficult to police - if we feel there has been a transgression in this regard, we can investigate and file a complaint with the Independent Communications Authority of SA (ICASA), and it will then take the necessary legal action,” says Weldrick.
