[Chris Boyd]

Yeah, we’re just an 800 person enterprise shop, so no SS7. And yes, the Lumen conglomerate can be a pain to deal with.

We learned that when we tried to port a number from Lumen and found out it used to be Century Link, but was transferred to Bright Speed, then somewhere else.

In this case, I need to figure out which carrier routes a toll free number we use so that I can open a ticket with them. I thought we used Lumen for all voice services, but they say the number does not belong to them. Any pointers to places to look this up would be appreciated.
