This is a filtered version of the alternative groundcrew of the user Q_FLYER and is done with his permission.
I have changed only the voice files to sound more like coming over an intercom connection and therefore added some distortion.
Just replace the files to the files in the folder:
[fsx-root-folder]/SimObjects/Airplanes/Aerosoft Airbus X Extended Base/Sound_ASC
Make sure, you copied a backup of the folder before doing any changes to it.
Have a nice flight!
