NAT traversal....????
http://www.spectrum.ieee.org/select/1098/int.html
NATs are a no-no
HEATH: I was going to say that IEEE Spectrum should make it very clear that
this group's consensus would appear to be: let's
discourage NATs--I mean the manufacture of them at all--because there is a real
need for IPv6.
HUITEMA: It's more than that. There is a real need for security and you can't
have security with NATs.
CERF: NAT is a guaranteed spoofing box in effect.

Agreed. To enable access from behind firewalls (ie: homes, hotels,
conferences, airports, Asia, ...), we can donate a B2BUA-based NAT traversal
solution for SIP (same one that Pulver's Free World Dialup uses). It sits
near the proxy, with nothing needed on the client end.
Bottom line: In addition to helping the IESG and IAB, it will help SIP to
have more IETF participants gaining experience with it.

That's great idea. We can help with our free SIP server (www.iptel.org/ser/)
and hosting the services.

There are excellent SIP voice conferencing bridges available, such as
from snom AG and eDial. They can be used with various soft clients such
as the Windows Messenger, HotSIP Active Contacts or the Pingtel instant
expressa, or any SIP phone.
I have taken the liberty of copying here the contacts for snom AG and
eDial, in case this will be pursued. I wonder if snom AG or eDial would
just give the IESG and IAB access to their conference servers?
Would there be interest to have access to a WorldCom SIP conference
bridge?
Thanks, Henry

Like many of us I was moved my Harald's appeal for
suggestions for helping
to cut down costs in the IETF.
I certainly endorse the idea of considering Canada or Mexico
as possible
sites for future IETF meetings, but I suspect that the weekly
teleconferece
calls that the IAB and IESG have represent a significant line
item for the
Secretariat.
In case anyone has not heard, SIP is quite capable of
handling this type of
task and there are a variety of commercial as well as open
source Client
User Agents as well as commercial products and services that
could help
reduce this cost.
I'm sure the SIP working group could help the Secretariat
identify products
and services that could make this essential function more
productive and
operate at less cost.
