Interactive Voice Response era (1980s–1990s)
Phone systems added automated menus and attendants that routed callers and answered routine questions without human operators. Companies bolted these onto existing PBX infrastructure. IVR became the standard way to handle high call volumes cheaply.
Routine inquiries shifted to machines, freeing agents for complex calls.
IVR shaped customer expectations and, for many, frustration. It became core contact center infrastructure rather than an add-on.
Voiso is attempting the same integration move with AI: making automation native to the platform instead of a bolt-on layer.
