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 :)
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.

Hi,
first of all, thanks Jonh, the zone is already ok.
William, I will reply to your call when I have outbound
calls configured with ISN queries and thanks for the test
:).
Secondly, I have one more question regarding the resolver
system that are described in the freenum documentation
that simply converts ENUM like queries in ISN (IP:
216.218.159.179.). I
tried to test it, but it seems that is not answering
queries. If possible, I would like know more technical
information regarding it, more specifically which software
is performing this kind of proxy DNS, if it is opensource
or if it is proprietary and if we can have access to it to
test it in a more specific environment.
Best regards,
Paulo

Hi
Jonh,
thanks for the quick reply.
Strange that your first dig failed, because I already had
the zone configured in both name servers since last week.
Regarding a number for dig testing purposes (it isn't
configured yet on my testing environment systems), for
example, you may use 5178*1764 as you can see bellow.

Hi,
my name is Paulo Ferreira and I'm working in VoIP team
at the Portuguese NREN and I'm testing ISN numbering
method in some trial environments.
I'm not sure that this is the right place to post this
issue, but because I'm not getting any answers from
other channels from freenum.org, I'm
sending this email to ask you if you already faced
this problem and how to solve it.
Sorry about the no reply to the
address - it was marked as spam for some reason. I've
cleared the flags on that mail.
I've configured my ITAD zone in
freenum.org
app to delegate it to my name servers. When I click in
"View DNS", the app show me the configuration of my
ITAD zone ok, pointing it to my name servers as
configured, but when I query freenum.org
name servers I cannot get poositive answers to that
configuration. I already sent an email to
in the past week but I got no answer.
There were two problems with the zone:
1) The zone had not yet been manually approved for
inclusion into the DNS. All new entries get a human
approval process before they are permitted to be added
to the zonefile (this is not clearly documented, and I
apologize for the confusion - even though you were able
to log into the web interface, the entries are held
until approved.)
2) The zone didn't appear to be correct on your
nameservers, or was somehow missing. I just looked at
your configuration this morning, actually, and noticed
it was a bit unusually configured. Here's what I get
when I looked at your zone earlier today:

There didn't seem to be a correct SOA in there. Now,
looking at the same zone just a few moments ago shows
what I think is the correct answer for the zone:
zot9:jtodd$ dig @ns01.voip.fccn.pt.

I'd need to know a "valid" number to fully test to see
if your nameserver has the right records. If you had an
NAPTR entry for 1234*1764, I would do a "dig" like this:
zot9:jtodd$ dig @ns01.voip.fccn.pt.
NAPTR 4.3.2.1.1764.freenum.org.
Currently, that query returns no values but that's OK
since I don't know if that is a valid number. If you
were going to be putting a wildcard in there, then it
should reply back with a valid NAPTR result.

Did someone had issues like this
one?
