IVR meaning: what Interactive Voice Response does for a business

IVR stands for Interactive Voice Response, the automated layer that answers an inbound call, presents the caller with options and routes them to the right person or queue. This article explains what the term means, how the system handles a call from ring to connection, what a business actually uses it for, and where an IVR still earns its place alongside a conversational voicebot.

Voicebot versus traditional IVR: when each one wins

IVR menus and voicebots get compared as if they were two versions of the same product, but they answer different questions.

The right answer for a UK business depends on call volume, the variety of reasons people ring and whether the goal is routing, answering or both.
