STUN is indeed a great protocol, with all the right

type of NATs and about the structure of the network.
Indeed, but its assumptions are well in line with the predicted
clientele: home/soho.
We were talking about SIP; enterprises do not have too much of a problem
with SIP and NAT, because a) they have a somehow knowledgeable staff b)
they can deploy gateways/proxies/whatever at the edge of their network,
where NAT occurs. If SIPPhone and FWD can deploy SIP proxies, so can
Microsoft, Cisco, and a bunch of others. SIPPhone, FWD and consorts do
already connect together and there are beta tests to connect private
Call Manager domains to them.
