draft-ietf-sipping-nat-scenarios-13 section 5.2.2.2 TURN Solution shows
a user agent sending two Alloc Reqs to a TURN server for its two media
ports (RTP + RTCP). The TURN server returns (message (3)) STUN-PUB-2 for
the first Alloc Req and (message (7)) STUN-PUB-3 for the second Alloc Req.
Surely STUN-PUB-2 is not necessarily the same as STUN-PUB-3?
I would imagine that in most environments it would be, but if it's not a
MUST, what does one do in the SDP, given that "a=rtcp:$STUN-PUB-3.port"
defines the port that RTCP will use, but not the address?
