Setup PBX auto attendant operation

After a caller enters some keys, an auto attendant can:

- transfer the call to an extension, or
- go to a sub-menu (another auto attendant)

If a caller… the system should: An auto attendant responds to caller input defined in the “if a caller” box, and carries out operations defined in “the system should” box. The following figure shows an operation that if a caller presses 2, transfer the call to extension group Sales.
