[VoiceOps] Looking up which carrier routes a toll free number

[Chris Boyd]

I’m a data guy who knows enough about voice that I sometimes get handed tickets for voice services. 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.
