I have a customer who is looking for a particular DID. (I dialed it and it is not in service). I searched through my preferred upstream provider‘s list but I came up empty. I wrote them, and this is their reply.
“We currently do not have that specific number in stock as this number is owned by another carrier that we do not have a business relationship with.”
So my question is this. How do I find out which carrier owns the DID in question?
