I did that for the ones I knew of and yet still have a non-zero amount of numbers where I don't know where they live. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Ross Tajvar" <ross at tajvar.io> To: "Mike Hammett" <voiceops at ics-il.net> Cc: "VoiceOps" <voiceops at voiceops.org> Sent: Friday, March 17, 2023 3:32:53 PM Subject: Re: [VoiceOps] Off-Net Numbers Surely you have commercial relationships with these entities, and can work backward from "who am I paying?"?

I have off-net numbers configured in my Metaswitch where I don't know who our upstream was, if we still have them, who they belonged to, etc. I can easily figure out what CLEC has them now, but we all know that there was probably someone between me and them, I just don't know who. Is there any likelihood of being able to determine that? I assume the different CLECs that "own" these numbers are not going to tell me who their reseller was, for me to then follow up with. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
