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.

Surely you have commercial relationships with these entities, and can work 
backward from "who am I paying?"?

Historically, we used multiple entities to get us off-net numbers. Who, what,

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.
