I mean, call them and see what trunk group they come in on. Surely there must be a hint like that somewhere. They can't come in out of thin air.

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<http://www.ics-il.com/> Midwest Internet Exchange http://www.midwest-ix.com<http://www.midwest-ix.com/> _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org<mailto:VoiceOps at voiceops.org> https://puck.nether.net/mailman/listinfo/voiceops
