What is IVR (Interactive Voice Response)?
An automated phone menu that routes callers based on touch-tone or spoken input.
IVR — Interactive Voice Response — is the technology behind classic phone menus: 'Press 1 for sales, press 2 for support, press 3 for billing.' It first appeared in the 1980s and has been a staple of business phone systems for decades.
IVR is good at routing calls in large organizations with clear departmental structures. It is famously bad at handling anything off-script: a caller with a question that does not match a menu option will get stuck or hang up.
Modern AI receptionists are sometimes described as 'AI IVR,' but they work very differently. Instead of a fixed menu, the caller just talks normally and the AI understands the intent — no menu trees, no button presses, no dead ends.
HOW CALLARA USES THIS
Callara replaces traditional IVR menus with natural conversation. Callers get answers in one sentence, not five button presses.
