Definition & Meaning of "answering machine"in English

What is an "answering machine"?

An answering machine is a device used to record phone messages when the person being called is unavailable to answer the phone. When someone calls, and there is no response, the answering machine automatically picks up the call after a set number of rings and plays a pre-recorded greeting. If the caller leaves a message, the device records their voice, which can be played back later. Answering machines were commonly used before voicemail became popular, and they are still found in some homes and businesses, although digital voicemail services have largely replaced them.
