NRENum.net

An ENUM service for academia by the National Research and Education Networks (NRENs) organization (via the Trans-European Research and Education Networking Association - http://www.terena.org/ Links to an external site. ).

NRENum.net uses a private dialing plan, as an alternative to the "e164.arpa" zone (known as the Golden ENUM tree).

It is recommended that a VoIP should query both the e164.arpa and the nrenum.net trees.

NRENum.net enables universities and research organizations:

to interconnect their VoIP systems - without having to do so through a traditional telephony operators

to list E.164 numbers and also: telepresense, Global Dialing Scheme (GDS) numbers (a numbering plan for H.323 services), …

Transcript

[slide234] There's an NRENum.net, and they're basically taking an interesting approach, which is they introduce a parallel tree to the ENUM tree. Right? Because it's just another DNS root, and they call it the golden ENUM tree. And now they let you basically have numbers inside this new numbering plan. Because the numbering plan doesn't have to match phone numbers, you can now have numbers inside that, so for example lots and lots of universities have things like telecommunication equipment, it was typically designed to have modems, you called a phone number, you want to set up a video between this meeting room on your campus, and a meeting room on another campus. And someone said: Why do we need phone numbers for these things that map to real telephony number, in the real world. We can simply have a thing that look like a phone number, acts like a phone number, but really is simply sent through this voice over IP network.
