IVR (Interactive Voice Response)
A legacy phone system that uses pre-recorded menus and keypad input to route callers.
Interactive Voice Response systems have been the standard for automated phone handling since the 1990s. They play pre-recorded messages and use DTMF tones or basic speech recognition to navigate callers through menu trees.
The fundamental limitation of IVR is rigidity. Callers must follow predetermined paths, and any deviation leads to frustration. Studies show that 83% of callers will avoid a company after a poor IVR experience.
AI voice agents represent the next generation of phone automation. Instead of forcing callers through menus, they understand natural language and respond dynamically.
