43780

+43 780 - ENUM driven number range

An ENUM driven number range - +43 780 - was introduced in Austria by the local regulator (RTR GmbH) in May 2005. This number range is specifically to be used with ENUM for "convergent services", and is the prime choice for VoIP services in Austria.

Contrary to other ranges, numbers in this range are allocated together with the respective ENUM domain: Instead of registering the ENUM domain for an already existing number, the ENUM domain is the precondition to get the respective number assigned. This makes this number range look like a "traditional" domain: find a free number, register the corresponding domain, receive the number together with the domain.

Another distinctive feature is that calls to numbers within this range can be terminated directly via the internet by using information provided by ENUM - communication network providers are not obliged to terminate the traffic to the number range holder in question. This "integrated" gateway functionality makes it especially attractive for VoIP and similar services.

In contrast to other number ranges the administration of numbers is simplified for service providers because of these features: It is not necessary to set up new routing for new number since the number range as a whole can be routed to a gateway of the carrier's choice. The process of number allocation and relinquishment with the regulator can be fully automated.

Reachability test - call for participation

As with all new number ranges, +43 780 is not yet reachable from all networks, especially not from carriers of other countries than Austria. Please help us to test this number range from foreign carriers, and add your test results to the table below.

How to test

You can test this number range by dialing the number +43 780 004711 (test number provided by "nemox.net"). If you hear the word "ENUM" followed by some music, you can successfully reach the number range from the network you were using. Please indicate the results of your tests (whether it did work or not, what kind of error announcement you received) below. Thanks for your participation.

If it does not work, please try the same number again (+43780 is DNS based and DNS may be slow sometime)

Re-testing


If the result of a certain carrier is No in the table below, and the repsective result is older than 2 weeks, you are encouraged to re-test, and indicate the results of your test as well. If the result is still negative, please indicate so in the comment (e.g. "retested on 2005-11-02"). If the number works now, please update the row accordingly.

To service providers

If you can't reach the number range or need more detailed information on how to route those calls drop us a mail at "office@enum.at".
