There are two ways to solve this puzzle. The primary method
reveals the final coordinates directly in the
4.5.7.8.1.3.4.1.4.0.4.9.4.e164.arpa DNS records. How, it's up to
you to figure it out.
The alternative method, which might be a lot easier, includes
leaving a voice mail message to my SIP/VoIP answering machine at
sip:5159490638@proxy.freedigits.net stating your email address and
informing that you want the ultimate spoiler for the ENUM Phone
Numbering mystery. Download for instance the GizmoPhone client
program for your operating system and call the SIP URI above. If
you're using a real telephone, note that you'll need a touch
tone handset to bypass the telemarketing screening I've turned
on by default.
Either way, you should learn something new from the future of
your telephone numbers. Please, when you find this one, rehide it
carefully.
