Hi, as you probably know, Austria has a dedicated ENUM driven number range in place since May 2005: +43 780. Reachability of numbers within this range from the PSTN is good within Austria, but still a patchwork from abroad (as with all new number ranges). it is very hard to debug PSTN connectivity from the receiving end - which is why we are asking you dedicate a few minutes of time and a phone call. To collect the information we've set up a Wiki page: http://www.voip-info.org/wiki/view/43780 To help us make it better, follow these steps: - take a "conventional" phone line of your choice (PSTN, mobile - the more data points, the better) - call the test number "+43 780 004711" - if you hear the word "ENUM" followed by some elevator music, routing from your telco is ok - perfect! - if it doesn't work, take a note of what happened (announcement, error message, error indication etc.) - leave a note about your success or failure to the wiki page indicated above. If possible, add rate information. - repeat this test for any carrier you have access to. If you detect a failure, and happen to know or work for the telco - please notify the relevant person to fix the problem, it is theirs. We're happy to talk to them if you get us in touch. Thanks for your help - we really appreciate it. Feel free to forward this message to people who might contribute more data points. thanks, Alex Mayrhofer enum.at
