Invention: VoIP Mangling

Barry Fox writes on NewScientistTech:

A patent application from German company Infineon reveals a technology for deliberately interfering with internet telephony transmissions - or "voice over IP" (VoIP).

The application doesn't expand on why it would be used. But it could conceivably come in handy for any company that operates both phone and internet services and would like to protect their phone business from the growing popularity of VoIP.

According to the application, a machine on a computer network would analyse passing "packets" of information, distinguishing between data and voice ones. After identifying a series of voice packets, it would add extra "pseudo-packets" to the communications stream. These packets would be labelled as voice but actually contain nothing useful.
