Depends. In older versions it is in the Manager directory.
c:\program files\avaya\ip office\manager
or
c:\program files (x86)\avaya\ip office\manager
On a 500v2 it is automatically self created unless you have created one manually to add specific features.
You can edit the one in the Manager folder and upload it to the Primary folder on the SD card in a 500v2.
