In telephony an automated attendant also known as auto attendant allows callers to be automatically transferred to an extension without the intervention of an operator/receptionist).

Typically the auto attendant is included in a business's phone system such as a PBX, but some services allow businesses to use an AA without such a system.

The following lists common routing steps that are components of an automated attendant:

Transfer to Extension
Transfer to Voicemail
Play Message
Go To a Sub Menu
Repeat Choices

In addition, an Automated Attendant would be expected to have values for the following

'0' - where to go when the caller dials '0'
Timeout - what to do if the caller does nothing (usually go to the same place as '0')
Default mailbox - where to send calls if '0' is not answered (or is not pointing to a live person)

PBXs (Private Branch Exchanges) or PABXs (Private Automatic Branch Exchanges) are telephone systems that serve an organization that has many telephone extensions but fewer telephone lines (sometimes called "trunks") that connect that organization to the rest of the global telecommunications network.
