An auto attendant phone system is an automated call answering service for businesses. This system helps direct callers to the right department or person without needing a human to answer every call.
You may have come across an auto-attendant phone system when you called a business.
On an auto-attendant phone call, you are greeted by a pre-recorded message asking you to press a number based on who you want to talk to or what the purpose of your call is.
