Hello,
I have seen stun related code in sip-router core. Is there stun server, client or both implementations? Any special purpose for it?
Cheers, Daniel

You will at the very least need it for keep-alive in SIP outbound.

draft-outbound requires a STUN server running in the same port of the SIP registrar (or outbound proxy). It's the only way to make STUN working behind a symmetric NAT router (of course, just for signalling, RTP will not work).
