Legal Intercept on VoIP
It is not only Skype (see in the article), it is all pure VoIP calls
not going via centralized switches, only if a call is originating or terminating on the PSTN, you may intercept it.
Of course one could route a to be intercepted call via a special
server, but this would not be possible to be unnoticed by the
intercepted (another requirement)
So the only possibility to intercept a IP Communication is in the
access.

The Federal Communications Committee and the Justice Department are at loggerheads over a new problem in the war on terror: how to listen in on Internet phone calls. Thanks to the blistering growth of VoIP�Voice over Internet Protocol�services, which have been adopted by approximately 10 million people worldwide so far, law enforcement officials now worry that wiretapping may one day become technically obsolete. If traditional phone lines go the way of the horse and carriage, will the FBI still be able to listen in on Internet phone calls? How would it go about tapping one? Is it even possible? "
