Summary:                    [patch] STUN support not reliable
Description: 
Up front: This is not my report, but I wanted to make sure this does get
recorded. Having searched the bug tracker I found no entries on STUN, so I
assume that the problem is also to be found in trunk.

Taken from:
http://forums.digium.com/viewtopic.php?t=74252

thor: "more sniffing on the network explains why this problem happens.
when sending stun request asterisk uses the sip socket as the source and
the first packet after that, arriving on the sip socket, is assumed to be
the stun reply. If it happens to be another sip message then asterisk
throws an error because it does not verify if the packet is actually a stun
reply and blindly tries to parse it. this makes stun unusable with
asterisk."

After reviewing further feedback I've discovered that just about every part
of our current sip STUN implementation is done wrong architecturally.  This
all needs to just be re-written.  I'll see what I can do.
