CNAM on toll free?
by gfreeman＠sungevity.com Feb. 14, 2014

Feb. 14, 2014

Hi, folks, Can toll-free numbers have CNAM registrations? We're hoping to have it say something other than "TOLL-FREE CALLER", but our vendor says that toll-free CNAMs can't change. thanks, Graham Freeman gfreeman at sungevity.com

Fake Conferences CSCI and WORLDCOMP of Hamid Arabnia

Fake Conferences CSCI and WORLDCOMP of Hamid Arabnia If you have any thought of attending the world?s biggest fake conference in computer science, WORLDCOMP http://www.world-academy-of-science.org you must visit any websites below https://sites.google.com/site/worlddump1 or https://sites.google.com/site/dumpconf https://sites.google.com/site/moneycomp1 https://sites.google.com/site/worlddump4 The organizer of this conference is Hamid Arabnia http://www.cs.uga.edu/~hra a professor from University of Georgia, Athens, US. The primary goal of this conference is to collect registration fee by accepting all submitted papers. Several fake papers were published in the conference proceedings. He already earned millions of dollars from the registration fee and is using part of the money for anti-Christmas greetings campaign. http://worldcomp-fake-bogus.blogspot.com has additional information on this campaign. He recently started another new conference CSCI due to his hunger for money http://www.americancse.org Hamid Arabnia failed to reveal the reviews and reviewers' information for all the papers he received, despite repeated requests and challenges. The reason for his failure is there were no reviews and reviewers and he just cheated the research community for more than a decade by announcing that each draft paper is reviewed by two experts. We challenge him to publish these details at the conference website. Where are these experts? Where are these reviews? Soon he comes up with a story that he lost all the reviews and reviewers? information because of computer crash or theft. DBLP stopped indexing these conferences since 2011 and displayed an explicit message; The DBLP Advisory Board decided to discontinue indexing of this conference series. Visit http://www.informatik.uni-trier.de/~ley/db/conf/biocomp/index.html as a sample. He was forced to remove his name, the university of Georgia name, and university of Georgia email address from the conference?s contact page because the University has banned him from doing that. Do not spoil your resume by publishing in this bogus conference. Wikipedia?s comments on Hamid Arabnia are at http://en.wikipedia.org/w/index.php?title=Talk:Hamid_Arabnia&oldid Additional information on this conference bogus conference is available by searching internet using the keywords worldcomp fake or Hamid Arabnia fake Apologies for posting to multiple mailing lists. Spreading the news is the only way to stop this conference from harming innocent researchers. Respectfully, Many researchers cheated by Hamid Arabnia?s fake conferences

recommendations for PRI/POTS/DATA CPE device with fiber handoff
by myaklin＠g4.net Jan. 29, 2014

Jan. 29, 2014

All, I was looking at Adtran's website at the TA90Xe boxes because I swore they made a model with a SFP port but I cannot seem to find one. I am waiting for my Adtran SE to call back so I thought I would email the list and see what everyone else is using in this situation. We run fiber directly to the customer premise. The customer wants a PRI, 6 POTS, and 10-20 Mb/s internet. I want QoS on the upstream to be solid, I would prefer a device which can terminate the fiber directly, and run all the services from the same device. If my memory was incorrect and the TA90Xe does not offer a SFP port should I just stick a media converter in front of it or does anyone else have some gear to recommend? Thanks for any tips, matt at g4.net

The calls are being blocked... well, they'd have to be being blocked *before they get to your gaining carrier, I guess, right? That nearly *requires* the code to be in the LERG, so the originating CO can execute it. We have some people here who know the LERG back and fro; Paul? Anyone else? You ever heard of this? Can you originate a call to that number from a different carrier via PRI, and see which ISDN error you get back? Or have someone else call it that way? ISDN errors tend to have a bit more data in them. I'd do it, but I don't have any PRIs laying around anymore. Cheers, -- jra -- Jay R.

Hi all, I am wondering if anyone has ever heard of DIDs that are restricted so that only intra-lata or local calls are allowed to complete. We have never come across this before, but we are being told that one of our DIDs falls into a block with these restrictions in New York. Any pointers to information about this would be appreciated. Thank you, Tim

Sort of off-topic, but sort of on. Looking for something that I can plop in some CDRs and paint a nice pretty heat chart picture of where calls are going. Anyone ever undertaken a similar task, if so, would you have a software you'd recommend.
