1A voice storage system: Voice storage in the network — Perspective and history

In mid-1976, Bell Laboratories undertook development of the then radical concept of introducing new customer services via a voice-storage capability in the network. With four systems installed and ready for service, the project was terminated in October, 1981, as a result of Federal Communications Commission (FCC) actions stemming from the Computer Inquiry II decisions declaring voice storage to be an enhanced service that could not be offered by the regulated network.
