Today, network admins face a very hard job trying to protect their internal LAN: if, 15 years ago, the Internet was basically a simple, yet large, client-server network, today we have a much varied environment.
One of the more difficult things to drop or block are P2P protocols: for their very nature, these protocols imply HTTP/S-tunneled client-to-client communications, and so they are quite hard to properly discover at the gateway level. Skype is one of these application: if it can not use its default ports, it tunnel itself into an HTTPS stream.
