Yeah, I think it's time for me to shut up about SIP/NAT problems and,
like you Carlos and Kevin pointed out,  run a clean un-contaminated
test lab to see if we can determine why our current set-up is so
problematic with SIP and NAT.

Thanks for offering to help. I will  set-up a test lab but it's gonna
take me some time to free a public server to do so.

But it is obvious that the problem is on our side after reading all
the responses. After all, VoIP is *not* by any means our core business
we just use it as a tool, and up until now I thought that *everyone*
using SIP ATAs and Asterisk had these NAT woes, so we just assumed it
was so, and thought that mostly everyone had to perform particular
configurations on the endpoints. It now seems obvious we are wrong.

Anyway, my whole argumentative line in this thread  is that in our
particular case we found that IAX2 works great for _our_ set-ups and
we don't share the view that IAX2 is a broken bat, and that in fact
for us it just works great.


Thanks,
