Indeed - and the pro audio lot certainly didn't use the name 'phantom'

Ever seen a phantom phone line? If anyone has the right to claim the
name, it is Western Electric.
A phantom circuit is a different thing. Usually only used in desperation
as the quality isn't as good as the discrete pairs.
If the lines were designed to be phantomed, as many long-distance
telephone circuits were, the phantom should meet the same spec as the
main pairs.
