One-X Attendant: automatic telephone directory refresh
 

What is the best option to automatically refresh the One-X Attendant ACM directory?
The documented way is: configure Avaya Site Administration on a Windows PC to do a periodic, automatic export of the Avaya Communication Manager stations to a text file and schedule MasterDirectory to import it automatically. Is there another method not involving Avaya Site Administration?
It seems that System Manager 6.3.x is not providing a bulk ACM station export tool, unfortunately.

I must say this is disappointing (source: 100180119_1_0_IAM_one-X_Attendant_407_CM_en.pdf): The delivered MasterDirectory cannot directly fetch the CM-data
