When you have written your ADSI script source files, store them in the $CUR_DIR/ca/ADSI_dir directory and follow the procedures in Creating your ADSI application to make them available for use by your voice application.
Alternatively, you can store your files in the $CUR_DIR/adsi directory. If you do, you will need to back up this directory yourself because it is not automatically backed up by Blueworx Voice Response.
