quick summary from wired.com:

http://www.wired.com/dangerroom/2010/02/how-to-smuggle-secret-information-with-voip/

"IEEE Spectrum found three different ways that messages could be  
encrypted and sent via VoIP, with little or no possibility for  
detection or interception. By delaying specific packets, corrupting  
packets, or changing the identification information of packets, users  
can sort out their message, which is then easily decoded by freely  
available software. In the course of a Skype call that only lasts a  
few minutes, massive amounts of data can be sent—without any detection  
or permanent record."
