[Asterisk-Users] NAT-helping outbound proxy

[ds-lists at thinkative.com]

Hi,

We're deploying a small VoIP solution for a group of teleworkers.
Naturally, this exposes us to all sorts of fun, most of which we seem to
have working properly. However, some NAT issues are still bugging us and
we have noticed that often these situations didn't exist when users were
connected directly to our VoIP provider, voiptalk.org.

They have something which they call a NAT-Traversal Gateway (see item 6 at
http://www.voiptalk.org/products/voiptalkfaq.html), which one configures
as the outgoing proxy, using port 5065.

Does anyone have any idea what this NAT-Traversal Gateway could be?
Naturally, I'm asking this in the hope that I can install something
similar on our server to solve our NAT issues.

Thanks in advance for your help.

Best regards,

David Shirley
