FAQ
Frequently Asked Questions
No. An answering machine only records messages. An audio response unit is interactive—it responds to user input (like keypad presses) with different pre-recorded information.
Almost exclusively in historical or technical literature about the development of telecommunication systems. In current business or IT, the term 'IVR' is universal.
Originally, it referred to combined hardware and software. Today, the concept is implemented purely in software, but the term 'audio response unit' is too dated to be used for these modern implementations.
It demonstrates how technical vocabulary evolves and becomes obsolete. Understanding such terms aids in reading older technical manuals or understanding the history of technology discussed in English.
