Hi,
It can quickly become a long discussion if no NAT traversal support is UA's fault. Most high end UAs are traditionally geared towards business market where there is no NAT issue. That's why NAT supports are not very good on them. Also at this moment there are just too many solutions which are not compatible to each other.
Going back to the real problem... In the short term, I think that the quickest solution is to find out a NAT device which allows inbound traffic to refresh NAT binding timer. I know that cisco PIX is one of them, but would like to find out if any lower end NAT firewall/router have it too...
Thanks, Richard

I beg to disagree -- we should not create to much workarounds around imperfect clients. In particular, incomplete NAT traversal support is a serious shortcoming in a UA and I would discourage people from using such devices.
Other front to attack would be NATs -- there is an effort in IETF focusing on that, but that's obviously an activity which has no impact on currently installed base.

Hi Jesus,
Changing UA is not always a viable solution due to pricing and other technical issues. Every UA has something broken in its implementation and

would be very costly to change it because one thing (in this case, NAT) is broken.
Thanks, Richard

Use an UA that supports it (Sipura or Cisco for example).
