As someone who has been closely involved with the development of OpenSBC, the open source session border controller (OpenSBC is primarily developed and sponsored by Solegy), I always take pleasure (and not a little pride) when I find others who have been able to put it to good use.
The most recent example of this comes from the China Internet Network Information Center (CNNIC) - the Chinese equivalent to InterNIC, among other things. The developers there have used OpenSBC as the foundation for a proof of concept demonstrating that lawful intercept can be successfully implemented in a session border controller, and their proposed architecture has been submitted to the IETF as an RFC.
Lawful Intercept is the process by which legally sanctioned authorities are able to access private communications through a wiretap. This is challenging in the VoIP world for many reasons, not the least of which is because audio payload often follows a different path than call control signals when packets are sent over the Internet.
