I know the terminating carrier is what determines the Caller ID name displayed. If I understand the process correctly, if the number belongs to another carrier, the terminating carrier does a 'lookup' in the CNAM database. If for example, a number is serviced by Windstream, and a Caller ID name change is requested - that change is propagated to the different carriers by Windstream. In a particular case I'm working on now, several terminating carriers are showing the old Caller ID text. Frontier Comm. is showing it correctly, but Xfinity and Ooma do not. I believe that Windstream has made the change since at least one other carrier (Frontier) showing the new Caller ID. Am I correct in saying Windstream is off the hook?

Delivering Caller ID info is the responsibility of the DELIVERING carrier. If a Windstream customer calls a Frontier or Spectrum customer, it's up to Frontier or Spectrum to provide the CID information to the end user. As a LEC/CLEC we deal with other carriers being a bit behind the curve all the time.

When we make a change or add a subscriber, our CID data base is uploaded to...somewhere. Other carriers have to get that info. Usually it's done on a regular basis, but each carrier has their own schedule.
