What an auto attendant actually is
An auto attendant is the recorded voice that answers your business number and gives
the caller a short list of choices. Press 1 for sales, press 2 for service, stay on
the line for a person. It is sometimes called a phone menu, a virtual receptionist or
an IVR. They are the same idea with different labels on the box.
It is worth being blunt about what it is not. It is not a receptionist, because it
cannot answer a question. It is not an answering service, because there is nobody
behind it taking messages. It is a signpost. It listens for one keypress and sends
the call somewhere, and that is the whole job.
Extensions are the somewhere
An extension is a short number that belongs to a person or a department. Dial it
from inside the business, or press it from the menu, and the right phone rings. On an
older office system that extension was a physical wire running to a physical desk,
which is why extensions used to mean a building full of people.
On an internet based phone system, an extension is a label attached to a person. It
follows them to whatever they answer calls on. That single change is what lets three
people in three different places sit behind one business number, and it is the part
of this product that small businesses get the most out of.
So there are two purchases hiding under one name. The menu is optional. The
extensions, the greetings and the routing behind the menu are the parts almost every
business uses, whether or not a caller is ever asked to press anything.
