Hi all,

This draft provides a way for firewalls to authenticate attempts to
initiate UDP flows from within an enterprise using extensions
to STUN protocol. This draft was earlier submitted to RTCWEB and the
authors were asked to take the discussion to MMUSIC WG by the AD.

Your comments are welcome.
