Hi Jonh,
last but not least, and because I forgot to put it in my previous
email, thanks for you help on this.
Regards,
PF

Hi Jonh,
for feedback about my tests, I tried to compile the app you sent
me but in order to compile it with seccess I had to change some
code on it, but after that I was unable to test it because it
was always returning to me an error when I tried to query it
with an ENUM like ISN query.
I identified the error but no success with resolving it,
probably because I'm not a pro with C++. So avoid losing more
time, I developed a quick perl daemon to do the DNS proxy thing
an test it with success.
After that I configured kamailio with this daemon as redirect
server for integration with my voice infrastructure for testing
purposes with success in outbound calls to ISN numbering scheme.
Best regards,
Paulo

Paulo -
I need to update that documentation (and will
in a few hours) - the IP address is incorrect for
that resolver. The current correct IP address is
64.62.236.143 (which is www.freenum.org.)
It's a special resolver shim (called "shotgund" for
historical reasons) that will convert an ENUM query
including "*" characters into a correct ISN
response. It also does a bunch of other interesting
things, like parallel ENUM tree resolution, and
domain re-writing. For a better explanation, see my
"dig" example below. The ENUM query is incorrect as
far as the RFC is concerned - it includes the "*"
character - but I found that at least a few years
ago, most ENUM libraries would include the "*"
character when sending out queries externally to
resolvers, so this hack can work.
I tried to use the resolver you sent to me, as you can
see bellow, but no success, maybe it is filtering some
IP traffic from this part of the world :)
OK, that was my fault. I re-ran the process in the
foreground in high-debug mode to see if I could see your
incoming connections, and then put my laptop to sleep,
which disconnected the session. Please try again.
I can get you the source code for shotgund if
you're interested in running a local resolver, but
it's only marginally well documented and you may
have to tweak some settings to make it work for your
system.
Yes, I'm interesting to test it if possible and to get
more info online if exist. I tried to do a quick google
search but I didn't find any useful info regarding this
daemon.
Until now, it hasn't really available publicly - I
never did complete the documentation project on it, so it
was never announced. But now is as good a time as any.
This is actually a very complex (and dangerous)
application, but extremely useful. Let me know if you run
into problems - the source code and samples are here:
