Today, more and more in everyday life you can come across the concept of IVR (Interactive Voice Response). This is what, far from everyone knows, although they almost daily encounter this technology in real life. Let us try to give an idea of such systems, describing them in a generally understandable language.
IVR: what is it?
To immediately understand what such systems are, we give a simple example. Most of us had to contact the service center of the mobile operator one way or another. When you call, a greeting sounds and an offer to press a specific button on your mobile phone to select the section that best matches the request in the interactive menu.

Here's a quick summary of everything about a basic understanding of IVR systems. What this is was explained with the simplest examples, and the technical part of the question was not particularly addressed, since the subscriber trying to get information of an advisory nature does not need this. But in terms of a general idea of the principles of functioning of such services, this will be enough.
