[VOIPSEC] VoIP Sniffer

[Dittmann, Werner (NSN - DE/Munich)]

All,

regarding ZRTP: I've done an implementation of ZRTP in C++
and Java (both use the same architecture and structure). The
Twinkle SIP client uses the C++ implementation and the SIP
Communicator uses the Java implementation. Both implementations
use GPL V3 as license and are part of the GNU ccRTP project.

I've done a lot of interop tests with Phil Zimmermann's 
Zfone implementation and it works :-)

If you need some more information just drop me a line.

Regards,
Werner
