System information

Your application will be reviewed by a Real Human Being™, and within a few days you
should be assigned an ITAD by IANA. A few days later, you will also receive information
for your freenum.org account (there is currently a simple review process to ensure that
bots and spammers don’t abuse the system). You will then need to log onto the free-
num.org site and define the parameters for your ITAD.
Create a DNS Entry for Your ITAD
In the top-right corner of the freenum.org site, you will see a Sign in here link. Your
username is the email address you registered with IANA, and your password will have
been emailed to you by the freenum.org system.
§
You will be presented with a list of your assigned ITADs. In order for your new ITAD
to work, you will need to ensure the DNS records are up-to-date.
There are two methods of handling DNS for your ITAD. The first (and
simplest) is to have a NAPTR record inserted into the freenum.org zone.
The other way is to create a zone for your ITAD, and have free-
num.org delegate that zone to your name servers. We will only discuss
the first method here, but if you are familiar with NAPTR/ENUM ad-
ministration for a DNS server, you can use the second method.
The freenum.org folks have created the Freenum Automated Self-Service Tool (FASST)
to simplify DNS record entry for you. The essential fields will already be filled out. The
only thing you need to change is under the DNS Setting section of the form: specify the
hostname of your PBX and save the changes. The FASST tool uses a regular expression
to convert an ISN lookup to a SIP URI.
In order to specify your hostname, you will need to modify the sample regular expres-
sion provided by FASST, changing the sample hostname sip.yourdomain.com to the
hostname of your PBX. So, for example, in our case we would want to change:
!^\\+*([^\\*]*)!sip:\\[e-mail]!
to:
!^\\+*([^\\*]*)!sip:\\[e-mail]!
The other fields in the DNS entry should not be changed unless you know what you
are doing. The rest of the fields in the form are optional, and can be filled out as you
see fit.
§ This may take a few days, so if you’ve received your ITAD from IANA but not yet a password from
freenum.org, give it some time.
